13. ABSTRACT

The U.S. Army Environmental Center (USAEC) is evaluating the feasibility of using bullet traps on standardArmy small arms ranges. Currently on outdoor ranges, shooters fire small arms into earthen berms or far downrange into the soil. This deposits lead and other heavy metals in the soil and may lead to regulatory restrictionson ranges that might include closing the ranges. Bullet traps generally operate through either deceleration,impact or friction to slow and stop the bullet. This Technology Identification Report (TIR) reviews andprovides illustrative figures for eleven friction, five impact, and three deceleration type traps. In addition to an

extensive literature review, numerous site visits were made to discuss bullet traps with range managementprofessionals, commercial manufacturers and subject matter experts. This TIR identifies all known small armstraps that may be applicable to Army small arms ranges based on available manufacturers' performance data.Bullet traps may be a feasible solution to heavy metals build-up in soils currently experienced on Army ranges,if applied within the limits of the design parameters of each trap and the required Army training environment.

IEXECUTIVE SUMMARY

TECHNOLOGY IDENTIFICATION REPORTBULLET TRAP FEASIBILITY ASSESSMENT AND IMPLEMENTATION PLAN

I Numerous Department of Defense small arms ranges have the potential to build up lead and othermetals in soils. In some cases, those inorganic constituents may become mobile and migrate tosurface or groundwater. The U.S. Army Environmental Center (USAEC) is seeking ways toreduce the potential of off-site migration of lead and other heavy metals thus reducing thepotential impact on the environment at these ranges.

Bullet traps may provide a means to recycle the projectile material and prevent the contaminationof the range and the environment. The bullet traps would also mitigate the excessive soil erosionI experienced on outdoor ranges caused by the impact of the projectiles. In addition, bullet trapsreduce or eliminate safety problems caused by ricochets off natural or other materials on currentranges. Bullet traps, which are designed to capture bullets fired into limited cross-sectionalI areas, are currently being developed and marketed by independent commercial vendors and mayrepresent a feasible solution for some types of firing ranges. This Technology Identification

i Report (TIR) reviews the bullet trap technologies that are currently available.

A computerized literature search was conducted to identify potentially applicable bullet traptechnologies for use on outdoor ranges. Also, military installations were visited and nationallyrecognized experts were contacted to identify sources and types of bullet traps. Table ES- 1presents a summarized description of the identified bullet trap technologies.

Although most existing bullet trap designs are created for indoor applications, environmental

concerns and demands of the marketplace have encouraged several major manufacturers tomodify their traps for outdoor use. Bullet traps can be grouped into three broad categories,"deceleration, impact, and friction, though there is some blurring of the dividing line.Deceleration traps use a circular or helical chamber to allow the bullet to spin inside until it has3 shed sufficient velocity to drop through a recovery port in the bottom.

Impact traps include those such as the traditional steel or armor plate, concrete backstops, orother materials whose function is to cause the bullet to fragment or to be directed into acatchment area. Their advantages are that they are generally inexpensive to construct, lowtechnology, reasonably durable, and require little maintenance. The disadvantages are that theycause bullet fragmentation, with the consequent lead recovery and disposal problems, areessentially immobile, and can contribute to ricochets.

Friction traps include a variety of traps from the earthen berm, to some very esoteric designs.These traps cause friction on the surface of the bullet, slowing its flight and bringing it to a stopwithin a defined distance. Their methods and materials vary widely, as is shown in the followingdescriptions. The advantages of friction traps are that they generally capture the bullet intact,though with varying degrees of deformation and can be more easily tailored to the mission.Disadvantages are that they generally require more maintenance, and are more expensive toconstruct, though some types are promoted as being the lowest cost of all categories.

A number of indoor designs, such as the Passive Bullet Trap at the new National RifleAssociation indoor range in their headquarters in Virginia, are quite innovative, but also quiteI expensive. Most companies who list themselves in trade publications or compendia such as theThomas Register, are really assemblers of other companies' materials or are target not bullet trapmanufacturers. Those who are true bullet trap manufacturers are few and do not advertiseI widely. Consequently, they are hard to discover. To date the market had been rather limited andnot able to support large numbers of manufacturers. In the past, the dominant designs were of thedeflection type and therefore easy to manufacture locally. Due to an abundance of land, mostI shooters could travel a short distance from home to fire on an outdoor facility backed by aearthen berm; therefore, demand was limited. A worldwide search was conducted to includeCanada, Scandinavia, western and eastern Europe, Japan, Korea, Australia and New Zealand. Ofthe foreign countries investigated, only Germany, Italy and Switzerland had manufacturers.Some of the traps that have been investigated appear to be viable candidates for someapplications on Army outdoor small arms ranges. However, manufacturer's performance claimsshould be verified by demonstration under operational conditions to provide objective data on thetraps ability to contain or prevent the spread of heavy metals on the range as well as thedurability, maintenance requirements, effects on training, life-cycle cost, and utility of thesetraps.

SECTION 13TINTRODUCTION

1- 1.1 Background

I_ Numerous Department of Defense (DOD) small arms ranges have the potential to build up leadand other metals in soils In some cases, those inorganics may become mobile and migrate tosurface or ground water. The Army currently operates approximately 1400 outdoor small armsI ranges in the Continental United States (CONUS). The Navy operates approximately 270outdoor small arms ranges (including Marine Corps ranges) and the Air Force operatesapproximately 200 outdoor small arms ranges. The U.S. Army Environmental Center (USAEC)is seeking ways to reduce the potential for off-site migration of lead and other heavy metals thusreducing the potential impacts on the environment at these ranges.

An effective technology for destroying lead and other heavy metals deposited in soil does notexist. Techniques that limit the volume of heavy metals deposited in the soil will providesignificant cost avoidance if these sites require some type of response action. Theimplementation of bullet traps will limit or prevent the build-up of heavy metals in soils.

3 This report identifies and describes commercially available outdoor bullet traps that capture and"contain small arms projectiles.. These devices may provide a means to recycle the projectilematerial and prevent the build-up of heavy metals in the soil on the range. Bullet traps may alsoI mitigate the excessive soil erosion experienced on outdoor ranges caused by the impact of therounds. Erosion control and soil stabilization on the ranges may help prevent the migration ofexisting heavy metals off range and may help alleviate the recurring costs of land rehabilitationon the ranges. In addition, bullet traps may reduce or eliminate safety problems caused byricochets on existing ranges. Bullet traps may represent a feasible solution for some types ofI firing ranges.

1.2 Objectives

The overall objectives of this project are to assess the feasibility of using bullet traps on Armyoutdoor small arms ranges and to develop an implementation guidance document for the use ofbullet traps on various types of outdoor training ranges.

To meet this objective the following principal technical tasks were performed:

£ Identify and describe existing, commercially available bullet trap designs.

1 Study the various types of training missions and their associated range designs and develop

functional and mission specific operational evaluation criteria for various range designs.

0 Assess the feasibility of using each of the bullet trap designs previously identified. The bullettrap designs will be evaluated using the functional and mission specific operational criteria.Once the bullet trap designs have been evaluated, those that are considered to be the mostapplicable for use on outdoor ranges will be identified. Only the bullet traps that can be usedon a range without compromising the conditions necessary for effective training will berecommended for use. Possible modifications to existing bullet trap designs will beidentified which will permit the bullet traps to be used on outdoor ranges without impactingtraining objectives. The specific range types for which there are no feasible commercialbullet traps available will be identified. Possible methods of capturing the rounds forj recycling in these cases will be identified and discussed for possible future study.

* Develop an implementation guidance document that integrates feasible bullet trap technologywith training doctrine.

This report identifies and describes existing, commercially available bullet trap designs foroutdoor small arms range use. This report will serve as a compendium of currently availablebullet trap technologies for evaluation for use on Army outdoor small arms ranges. Section 2 ofthis report describes the investigation process used by TRW, Inc. to identify available bullet traptechnologies. Section 3 describes and discusses the identified bullet trap technologies.Conclusions and recommendations are presented in Section 4.

SECTION 2

LITERATURE SEARCH

Section 2 contains a listing of databases and keywords used to conduct the literature search foravailable bullet trap technologies. Preliminary screening criteria and the identified technologies3 are included. The results of site visits to Army installations are included. These visits yieldedinsights into factors to be considered in bullet trap use on Army ranges.

i 2.1 Methodology

In order to identify the available technologies for capturing bullets, a search of the research andtechnical literature was conducted through the following electronic databases:

TRW's Electronic Collateral Support System (ELCSS)-- DataTimes

Knight-RidderDefense Technical Information CenterComputer SelectNational Technical Information Service (NTIS)Thomas RegisterI Dun's IdentifierTrade and Industry Index

-= Dialog

These sources also included foreign publications. Some of the services, such as DataTimes,3 Dialog, and ELCSS were a compendium of numerous publication databases. ELCSS, forexample, searches more than 300 databases and Dialog more than 450. Numerous searches ofthe Internet were made and the National Rifle Association Range Technical Operations Team3_ was contacted for information. Several Jane's volumes were referenced also. Boolean logic wasused in the searches so that hits would be obtained even if only a part of a key word or term wasfound. For example, if bullet and trap were used, hits would be generated if bullet, bullets, trap,

-- traps, or bullet trap were found. It was felt this provided greater coverage even though manual"review of each citation was needed. Key words used in the electronic searches were:

a bullet trapsmall arms rangefiring range

i shooting rangetraining rangerifle rangebermoutdoor range"small arms" plus environment cleanupstopping bulletslead trap

i3- 2-1

Page 13: Bullet Catching Mechanisam

I

The results of each set of searches were compared with previous ones to eliminate duplicates.Little was found on the subject of bullet traps or bullet trap design even though numerous "hits"were obtained in the searches. For example, a search on "bullet trap" yielded 85 hits, but withthe exception of several articles on the purchase of Passive Bullet Trap by Challenger

I International, the articles dealt with an Israeli-developed rifle grenade called the bullet trap riflegrenade. This is illustrative of the problems encountered with the literature search. The hits hadto be manually reviewed and most contained little useful information. Almost all information'I was obtained via personal connections or referrals. There is very little in the published literatureon bullet traps, either indoor or outdoor, and virtually nothing on bullet traps for militaryapplications.

A number of Training and Doctrine Command (TRADOC) and Forces Command (FORSCOM)installations were visited to understand the types of ranges used, the training requirements, rangeI operation, and maintenance approaches. These visits were performed to develop evaluationcriteria for the second principal task outlined in Section 1.2. However, two of the installations,Fort Drum and Fort Knox, were experimenting with bullet traps and were able to providevaluable leads for identifying bullet trap technologies. Fort Drum has installed a Caswell lamellatrap on a 25 meter range (Fig. 3.2.4) primarily to prevent rounds from leaving the range and toprevent erosion. Fort Knox installed a series of log walls on a field fire range that had no bermto prevent rounds from escaping the range (Fig. 3.2.8). Thunder Ranch, a commercial firearmstraining school, was also visited to look at their innovative bullet trap design and to discuss theproblems of using bullet traps without impacting training effectiveness or realism. ThunderRanch needed a target/trap combination that was portable, but needed only to stop handguncalibers (Fig. 3.2.3).

Every source found to offer information on bullet traps was further pursued. The rather limitedresults of the literature search were digested and any leads followed. All personal or professionalI referrals were followed up with phone calls to potential manufacturers and designers. Contactswere made with the Marine Corps, FBI, and local law enforcement for names of knownmanufacturers. Several nationally recognized experts, such as Russell Friedline of the National

I Rifle Association Range Technical Team were consulted. Additionally, Loren Kramer, LarryTilton, and Craig Copious donated their time to answer questions, offer suggestions, and point toyet more sources. The military attaches at U.S. embassies in the United Kingdom, Italy, France,U Germany, Switzerland, Sweden, Canada, and Israel were contacted for assistance in identifyingforeign manufacturers of bullet traps. These efforts were combined with the results of literaturesearches and personal and phone interviews to produce the list of traps contained in thisdocument.

!5 2.2 Preliminary Screening Criteria

General Army requirements were discussed in general terms with the bullet trap manufacturers toaid in identifying prospective bullet traps for use on outdoor military ranges. The requirementswere used for bullet trap identification and data collection only. Bullet traps were not eliminatedfrom further consideration in this report based on the preliminary screening. Evaluation criteriafor the bullet traps will be fully developed and discussed in a separate report.

Preliminary screening criteria were driven by the Army's requirements and other factors, such asinstallation and life cycle cost, maintenance requirements, effectiveness in both trapping bulletsand preventing lead migration into the environment, and impact on training effectiveness andrealism. The bullet traps must be useable outdoors under inclement weather conditions. Anumber of innovative bullet traps are currently available for indoor range use. The manufacturersof these traps have developed modified versions of their indoor traps for outdoor use. However,,performance data from outdoor use of these traps is limited in most cases. In these cases,available data from the bullet traps indoor use will be used to help evaluate the traps.

SECTION 3I- BULLET TRAP DESCRIPTIONS

U Bullet traps are intended to perform one major function, stop bullets from traveling any furtherdownrange. They do this by a variety of methods and designs, most of which will be described3 in categorical terms in the balance of this section. In the past, the only consideration was to findthe lowest cost solution that would stop the bullet. For this reason, most were earthen berms.With the advent of specialized training, indoor ranges, and environmental awareness, the quest

ii for other methods gathered momentum. Factors in choosing bullet traps include its utility forrestricted space, safety, environmental impact, and disposal requirements. This document doesnot provide an analysis of the various bullet trap designs, but it does provide a technical

ii description and manufacturer's data to permit the reader to make a choice based upon theirunique requirements. Costs are not included at the request of the manufacturers. A number ofbullet traps and bullet trap manufacturers were identified. Many of the bullet trap designs wereI very similar. For example, one rubber composite block bullet trap offered by a British firmappears to be basically the same as that of a US manufacturer, Range Masters, with the exception5 of the presence of recovery channels in the Range Masters trap

Bullet traps can be grouped into three broad categories, deceleration, impact, and friction, thoughthere is some blurring of the dividing line. Deceleration traps use a circular or helical chamber toallow the bullet to spin inside until it has shed sufficient velocity to drop through a recovery portin the bottom.

Impact traps include those such as the traditional steel or armor plate, concrete backstops, orother materials whose function is to cause the bullet to fragment or to be directed into acatchment area. Their advantages are that they are generally inexpensive to construct, lowtechnology, reasonably durable, and require little maintenance. The disadvantages are they causebullet fragmentation, with the consequent lead recovery and disposal problems, are essentiallyimmobile, and can contribute to ricochets.

3 Friction traps include a variety of traps from the lowest, yet probably the most effective,technology, the earthen berm, to some very esoteric designs. These traps cause friction on thesurface of the bullet, slowing its flight and bringing it to a stop within a defined distance. Theirmethods and materials vary widely, as is shown in the following descriptions. The advantages offriction traps are that they generally capture the bullet intact, though with varying degrees ofdeformation and can be more easily tailored to the mission. Disadvantages are that theygenerally require more maintenance, and are more expensive to construct, though some types arepromoted as being the lowest cost of all categories.

* 3.1 Bullet Trap Technology Descriptions

5 Bullet Trap: GranTrap

Manufacturer: Caswell International Corp.I 1221 Marshall St. NEMinneapolis, MN 55413

* Method: Friction

3 Ballistics: .50 cal. and smaller

Construction: The GranTrap is a large vertical box comprised of a steel frame with aU steel backplate and steel or plywood sides. The front is a sheet of materialthat is identical to the large conveyor belts used in mines. The interior ofthe trap is filled with a clean, granulated, recycled tire material. There is a5 containment tray at the bottom front of the trap to collect bullets.

Capacity: Manufacturer claims 50,000+ rounds

Installation: 2 days, exclusive of site preparation. A level concrete pad is typicallyS required for installation of the trap.

Maintenance: Monthly is recommended. Caswell uses a two stage vacuum/blower toseparate the GranTex from the bullets in the collection trough at the frontI of the trap, recycling the GranTex material back in the top of the trap.Bullets are generally intact. Frequent patching of the rubber facingmaterial with sheets of rubber is required. The sheet rubber patch isinstalled with small screws.

Description: The bullet penetrates the front sheet and is halted, generally within the first12 inches, by the granulated material. As succeeding bullets impact thetrap, the preceding bullets are shaken down the column of granulatedI_ rubber and gather at the bottom in a trough where they can be collectedand recycled. There is leakage of GranTex from several locations on thetrap, but it is most noticeable at the point where bullet impact has chewedthrough the front strap. Even though a patch is placed over the hole,leakage still occurs. This is a licensed technology from Germany.

IBullet Trap: Total Entrapment Composite (TEC)

Manufacturer: Range Masters, Inc.199 Coon Rapids Blvd.Suite 304Coon Rapids, MN 55433

Method: Friction

I Ballistics: 7.62 NATO and smaller

"Construction: The TEC system consists of a set of large blocks molded from shredded,-- recycled tires in a matrix of Kevlar® reinforced bonding mixture. The

blocks weigh approximately 60 pounds each and measure about 30 x 12 x3 9 inches. The trap consists of a block matrix held in place by use ofjacking straps tightened to prevent any movement under impact. Theblocks are elevated on a platform which has an inclined plane underneathto cause trapped bullets to roll into a collection tray. The platform isprotected from stray rounds by ground baffles made of the same blocks asthe bullet trap. The appearance of the block is similar to an oversizedU. cinder block. Because of its modular construction, this trap is flexible indesign, and can be arranged in various height, width, and depth

* combinations to provide a larger backstop if desired.

Capacity: The manufacturer claims 10,000 to 20,000 round before the block needs to3_ be rotated, depending upon the type of ammunition used.

Installation: 4 hours, exclusive of site preparation. A level concrete pad is typically3 required for installation of the trap.

Maintenance: Inspect weekly and recover bullet from recovery tray. Rotate blockpositions within the trap as wear becomes evident, probably monthly, tomaximize life of the trap.

I Description: The interior of each block has recovery channels molded into it, allowingspent bullets to drop to the recovery area. The positioning of the recoverychannels can be customized for the type of ammunition used. PlasticI channel strips are inserted between blocks to more effectively channelspent rounds into the collection tray. The fired round penetrates the frontof the block, shedding velocity until it hits one of the recovery channels,where it falls into the collection tray. Particulates of the rubber compoundalso fall out the recovery channels, but not in great quantities. Recovery3 and recycle of the bullets is a matter of emptying the recovery tray. Bulletsare generally intact.

3 Bullet Trap: Thunder Ranch portable trap

Manufacturer: Action Target (assembled on-site)I P.O. Box 636

Provo, UT 84603

i Method: Impact

3 Ballistics: Handgun ammunition

Construction: The Thunder Ranch trap is an evolution of a design that, in one form or3 another, has been at a variety of training sites. The trap consists of 2 x 4lumber legs, approximately 6 ft. in height. The back is a 14 inch armorplate, 30 in. wide by 48 in. high, held in place by lag screws. On the front3 of the trap is a sheet of Linatex, a self sealing material similar to that inmilitary fuel tanks. On top of the Linatex is a plywood sheet on which thetarget is mounted. A piece of cardboard could also be used, as the

I plywood is primarily for cosmetics and insurance against fragmentspenetrating the Linatex near the end of its useful life. Around the interior

* perimeter is angle iron to deflect bullet fragments.

Capacity: Approximately 3,000 rounds before recommended emptying of bulletfragments. Life of the Linatex barrier will depend on the type ofammunition used, but is expected to be at least 10,000 rounds.

Installation: Minutes, exclusive of trap construction. The trap can be moved by twopeople.

Maintenance: Thunder Ranch inspects all traps weekly, cleaning as needed, generallymonthly.

Description: The bullet pierces the target and trap facing and hits the Linatex. TheLinatex stretches but is not penetrated until the bullet contacts the armorplate and fragments. The Linatex snaps back and seals, forming a barrier3to the bullet fragments. The fragments fall to the bottom of the trap forcollection. It is believed that by replacing the 2 x 4 legs with 2 x 6's, thelife of the Linatex barrier could be extended by up to 50 percent.Ammunition other than standard ball ammunition, such as hollowpoint,wadcutter, or frangible rounds, tends to cause accelerated wear of theLinatex.

Manufacturer: Caswell International Corp.1221 Marshall St. NEMinneapolis, MN 55413

IMethod: Friction

Ballistics: .50 cal. and smaller

Construction: The lamella trap consists of a series of strips of recycled industrial3 conveyor belts, about 10 feet long, hung in a herringbone pattern with theside to the shooter. The length of the conveyor belts can be varied to suitthe intended use of the trap. In addition, a smaller version of the trap,3approximately 3 feet square is placed immediately behind the target and infront of the main trap to slow the rounds and reduce wear on the main trap.

UCapacity: Manufacturer claims at least 50,000 round before replacement of thelamella strips.

SInstallation: Depends upon the size desired. A 110 foot wide trap took 15 man days toinstall at one range. A level concrete pad is typically recommended by the3• manufacturer for installation of the trap.

Maintenance: The lamella strips are replaced individually as necessary, and the 3-footmini-traps are placed to concentrate wear onto an easy to repair module.The trap should be inspected monthly during moderate use and bi-weeklyunder heavy use.

Description: The bullet penetrates successive layers of the strips until it sheds itsvelocity and falls to the bottom of the trap. The bullets sometimes imbedthemselves in the strips or, more often, fragment. As the individuallamella strips wear, they can be quickly rotated to other locations withinthe trap that receive less fire and the strips from those locations moved tothe high volume areas. The trap was effective in tests against all types ofsmall arms up to .50 caliber. This is a licensed technology from Germany.

IBullet Trap: Passive Bullet Trap - OP96

Manufacturer: Savage Range Systems, Inc.100 Springdale Rd.Westfield, MA 01085

I Method: Deceleration

Ballistics: .50 cal. and smaller

Construction: The OP96 is a three piece, helical deceleration chamber with steel plates* top and bottom in front set at an angle of 12 degrees from horizontal to

deflect the bullet into the trap. An injector introduces a fine spray of waterand water-soluble oil at the point of entry into the deceleration chamber tocoat the bullet. The bullet spins around the chamber until it runs out ofvelocity and it slides backward to drop through a slot in the bottom of thetrap into a collection tray. The unused spray is recycled back into aIreservoir which feeds the injector. The initial contact portion of the trapitself is bolted on to allow for easy removal and replacement as it wears or

* as different ammunition types are captured.

Capacity: Depends upon the type of ammunition being fired and the capacity of thecollection tray. Up to 25,000 rounds between emptyings of the collectiontray can be handled before there is the beginning of a danger of backing upinto the trap.

I Installation: Installed in modular units by the manufacturer. A level concrete pad is

typically required for installation of the trap.

Maintenance: Collection tray and spray reservoir should be checked weekly andmaintained as needed. The initial contact portion of the trap is anticipatedto last for at least 250,000 rounds.

Description: The OP96 is based on a centrifugal deceleration principle. The fired roundis directed into the mouth of the trap by two angled collection platespositioned at an angle of 12 degrees from the horizontal. The round thenspins around in a circular path inside the trap until it loses velocity. It thendrops down into a collection container. The trap comes in both indoor andoutdoor designs. In the indoor version, the contact surface of thecollection plate is washed with a fluid consisting of water, mineral oil, andethylene glycol. This serves the purpose of a lubricant and suppresses leaddust thereby reducing the respiratory hazard to shooters and rangemaintenance personnel. The wash fluid is filtered and recycled back overthe collection plate. In the outdoor version, the collection plates are notwashed with a fluid. Instead, a fine spray of water and soluble oil is

* 3-6

Page 26: Bullet Catching Mechanisam

Idirected at the entrance of the OP96. As the bullet enters the trap, itreceives a coating of lubricant which prevents lead dust from forming andreduces wear on the trap. Other than that differentiation, the designs areU essentially identical. Both traps can be manufactured to the users desiredwidth.

Manufacturer: Capito and Assenmacher44319 Dortmund Wichkede44311 Dortmund

3 Germany

Method: Friction

SBallistics: .50 cal. and smaller

SConstruction: The trap is a large vertical box comprised of a rubber curtain made of aconveyor belt material in front, an air space, and 2 inch thick polyurethanesheets, one meter square, as the front panel. The sides are plywood andIthe back is armor plate. The interior is filled with a soft rubber granulatedmaterial which is coated with something resembling baby powder. Thetrap is one sheet (1 m) wide, four sheets (4 m) tall, and one meter in depth.There is an access door at the rear of the trap to allow removal of thegranular material and bullets by means of a truck-mounted vacuum andsifting system. Following separation of the bullets, up to 80 percent of thegranular material is recovered and recycled back into the trap.

I Capacity: Manufacturer claims 25,000+ rounds

Installation: 4 hours, exclusive of site preparation, which requires a level concrete pad

I Maintenance: Monthly is recommended. Bullets are generally recovered intact.Polyurethane sheets are replaced infrequently and require removal of thegranular material. The rubber facing is repaired by rubber patches arescrewed to the front of the worn-out facing.

Description: The bullet penetrates the front curtain and polyurethane sheet and ishalted, generally within the first 12 inches, by the granulated material.Pistol rounds penetrate somewhat less, rifle rounds, somewhat more. For9mm pistol rounds fired from 25 meters or farther, the bullet will penetratethe front curtain, but will not penetrate the polyurethane sheet. Instead, itbounces off, rebounds to the front curtain, and falls to the bottom. In testsconducted so far, tracer rounds have had no noticeable effect.

* Bullet Trap: Railroad Ties or Log Piles

Manufacturer: None

Method: Friction

- Ballistics: .50 cal and smaller

Construction: This is a simple outdoor trap in which railroad ties or logs are stacked-- perpendicular to the axis of firing. They can be stacked several deep and

as high as the desired target height. In certain cases these can be made into3 a crib and filled with dirt.

Capacity: Depends upon the types of ties or logs being used and the types ofammunition fired into them. Several thousand rounds should be able to befired before noticeable degradation occurs,

U Installation: Varies from a few hours to several days depending upon how large andelaborate the stack is made and whether it has filler added.

I Maintenance: Repair usually requires disassembly of the backstop to removedisintegrated ties and insert new ones. Disposal of the shot-up tie may fall

I under RCRA controls.

Description: Rounds passing through the target impact the railroad ties or logs and arestopped. The advantages to this design are that is easy to construct withtroop labor and it reuses material that is available in large quantities. Thedisadvantage is that the rounds are embedded in the ties and are difficult torecover. Additionally, after a lengthy period of firing, the ties disintegrateand could allow the lead to end up in the ground. This method is beingused currently to protect the front of cement target boxes, or coffins, at

Sseveral outdoor ranges and as a backstop in a few applications.

Bullet Trap: Sand Trap

S Manufacturer: Various

Method: Impact

i Ballistics: 7.62 NATO and smaller

Construction: This is one of the most widely used design in bullet traps because of theI simplicity of design, and ease of construction. A large steel plate thewidth of the lane behind the targets is mounted at an angle, tilted forward

- so that bullets are deflected downward into a bed of sand or dirt.

Capacity: Varies depending upon the size of the trap and the types of ammunitionI- fired.

Installation: Generally needs a construction or engineer company to install because ofI the weight of the steel plates. Construction/installation may take severaldays.

I Maintenance: Maintenance requirements are low. Bullet fragments are collected and thesand sifted on an as needed basis, probably no more frequently than

-- monthly, and perhaps less.

Description: Bullets impact the steel plate and fragment. The fragments are directeddownwards into the sand trap to be recovered later. On occasion, bulletfragments will escape the trap. The advantages of this system are itssimplicity of design, relatively low cost to construct, and ease of operationand maintenance. Disadvantages of the steel plate are primarilyenvironmental; airborne lead dust is created when the bullet strikes theplate, and at the same time it smears lead on the plate. When another3 bullet strikes the same place the lead residue on the plate contributes to theairborne pollution. Fragments sometimes fall outside the containmentarea. Cleaning the lead out of the sand bed requires personnel protectionmeasures.

SConstruction: A large steel plate the width of the lane behind the targets is mounted at anangle, tilted forward so that bullets are deflected downward into a watertrough.

Capacity: Varies depending upon the size of the trap and the types of ammunitionfired.

Installation: Generally needs a construction or engineer company to install because ofthe weight of the steel plates. Construction/installation may take severaldays.

Maintenance: Maintenance requirements are low. Bullet fragments are collected fromthe water trough on an as needed basis, probably no more frequently thanmonthly, and perhaps less. There is a potential for generation of solublelead. This may create a hazardous waste disposal problem.

Description: Bullets impact the steel plate and fragment. The fragments are directeddownwards into the water trap to be recovered later. The advantage overthe sand trap is its ease of cleaning. The disadvantages are that it requiresa larger trough and more maintenance, especially in colder climates.

3 Bullet Trap: Rubber Blocks

3 Manufacturer: Various, U.S. and International

Method: Friction

IBallistics: 7.62 NATO and smaller

Construction: These traps consist of blocks of various rubber compounds or recycledmaterials stacked to form a barrier. These are used to line shooting housesfor special operations personnel to train in, as baffles on walls and ceilingson indoor ranges, and as ballistic protection for damage-prone items suchas fuel pipes at aircraft arming areas. The blocks vary in size, but aregenerally around 60 to 80 pounds and measure 30 x 12 x 12.

Capacity: Depends upon the type of ammunition fired.

3 Installation: Half day, exclusive of site preparation.

Maintenance: Depends upon the type of ammunition used, but claims of 10,000 roundsare common.

Description: When the bullet strikes the block, the friction of the rubber on the bulletsurface causes the bullet to stop in a short distance, usually less than 2 feet.Their advantages are they are modular, so only the worn block needs to bereplaced, compact, and reasonably easy to move with -hand labor.Disadvantages are that there have been reports of fires from tracer rounds,disposal of the used blocks presents a problem, and there are unresolved£ questions about durability and cost.

5 Manufacturer: Various, U.S. and International

Method: Friction

I Ballistics: 7.62 NATO and smaller

Construction: These traps consist of blocks of various wax and plastic compounds or- recycled materials stacked to form a barrier. At the date of this report,

there are no manufacturers of these bullet traps still in business. The waxand plastic blocks operate on the same principles as the rubber blocks andthe Range Masters TEC blocks, being stacked or banded into the sizebackstop desired.

Capacity: Depends upon the type of ammunition fired.

i Installation: Half day, exclusive of site preparation.

Maintenance: Depends upon the type of ammunition used, but claims of 10,000 roundsare common.

Description: As in the rubber blocks, friction between the bullet surface and the blockmaterial stops the bullet, generally retaining it intact unless struck byanother bullet. The advantages are that these blocks are modular,compact, and easier to move with hand labor and tend to capture thebullets intact. The disadvantages are they cannot operate over the sameclimatic ranges as other traps, tend to melt somewhat under prolonged and

i closely spaced firing, and provide a disposal/recycle problem.

3 Manufacturer: Various

Method: Impact

IBallistics: 7.62 NATO and smaller

Construction: This is a widely used design in bullet traps because of the simplicity ofI design. In this design a steel plate is angled away from the firing line todirect the bullet upward into another steel plate. The bullet fragments are5 collected in a tray at the foot of the trap.

Capacity: Varies depending upon the size of the trap and the types of ammunitionfired.

Installation: Generally needs a construction or engineer company to install because ofI the weight of the steel plates. Construction/installation may take severaldays.

i Maintenance: Maintenance requirements are low. Bullet fragments are collected,probably no more frequently than monthly, and perhaps less.

I Description: The bullet strikes the plate and is deflected upward along or near the platesurface where it strikes another steel plate. At this plate the bullet spendsmost of its energy, and rebounds or fragments. It then slides down the faceof the larger plate and into a collection tray on the floor of the range. Theadvantage of this design is its ease of collection of spent bullets.5 Disadvantages include fragmentation of the bullet, the possibility ofrebounding, and the cost of manufacturing and installation. In addition,collection and disposal of the lead require proper personnel protectiveSequipment and adequate containers for the lead.

3 Bullet Trap: Steel Louvers with Sand Bed

3 Manufacturer: Various

Method: Impact

I Ballistics: 7.62 NATO and smaller

Construction: Like the larger downward angled deflection designs, this design arranges aI series of steel louvers in a vertical rack with each louver angled toward thefiring line. The steel louvers are approximately 12" to 18" in width andare arranged to provide some overlap between plates when rounds are firedat angles that are approximately parallel to the floor of the range. TheI spent rounds fall into a bed of sand beneath the louvers

Capacity: Varies depending upon the size of the trap and the types of ammunitionfired.

Installation: Generally needs a construction or engineer company to install because ofthe weight of the steel plates. Construction/installation may take severaldays.

Maintenance: Maintenance requirements are low. Bullet fragments are collected and the1 sand sifted on an as needed basis, probably no more frequently thanmonthly, and perhaps less.

Description: The primary advantage of this design is a saving of horizontal spacebehind the targets, and is usually only used on ranges where space is at apremium in an existing facility. The disadvantages of the regular steelplate and sand bed carry over to this design with the additional potentialI- hazard posed by bullets striking the leading edge of the louvers. Thechance of a bullet ricocheting directly back to the firing line is remote, butthis does increase the amount of bullet fragments and airborne lead dust.I Lead smearing on the deflector surfaces increases the potential for airbornepollution when struck by a succeeding round. Cleaning lead out of theg sand bed requires personnel protection measures.

*Bullet Trap: Tires

3 Manufacturer: Local recycle

Method: Friction

I Ballistics: 7.62 NATO and smaller

Construction: Soft containers such as old vehicle tires or large plastic barrels are filledI with sand or dirt and placed directly behind the targets.

Capacity: Varies depending upon the size of the trap and the types of ammunitionfired.

Installation: Can probably be done with troop labor under range management personnelguidance. Time depends upon the size and complexity of the trap.

3 Maintenance: Maintenance requirements are low. Bullet fragments are collected and thesand sifted on an as needed basis, probably no more frequently thanmonthly, and perhaps less. Tires are replaced on an as needed basis. Usedtires may need to be handled under RCRA controls.

3 Description: The advantage of this design is the ease of set up, and that it can becustomized to specific shooting range requirements. A variant of thevehicle tire trap involves nesting or layering the tires several thicknessesdeep and using no sand. Tire traps have been used for anti-terroristtraining in shooting houses for many years. When so many rounds havebeen fired into the face of the container that it ruptures enough to leak sandand lead onto the ground, the container can be rotated 90 degrees or moreto present a different face to the firing line, thereby extending the life ofthe container. Use of the tires provides a form of recycling.Disadvantages include the difficulty of recovering spent bullets, disposalof the used tires, and the need to completely disassemble the trap to repairit. In addition, there have been reported instances of ricochets of pistolbullets from the tire backstops.

3 Bullet Trap: Shock Attenuating Concrete (SACON)

Manufacturer: U. S. Army Corps of EngineersWaterways Experiment StationStructures Laboratory, Attn: CEWES-SC-EM3909 Halls Ferry RoadVicksburg, MS 39180-6199

3 Method: Friction

Ballistics: 7.62 NATO and smaller

--- Construction: SACON is cast into large panels 8' high, 3' wide and 22" thick. These

panels are fitted into steel I-beam brackets and grouped into walls. The3 primary application to date has been in shooting houses. With the abilityto pour and cure like regular concrete, however, SACON can be formedinto a wide variety of shapes and dimensions.

Capacity: 1,000 rounds before patching is needed.

SInstallation: Similar to other concrete construction: I day to pour, and 28 days to cure.

Maintenance: After 1,000"rounds, the SACON is eroded about 2/3 of the way through a22" panel. At this time, it is recommended that the void be patched withfresh SACON. This patch will also require a 28 day curing time. The3 alternative is to replace the panel from a stockpile of precast panels.

Description: SACON is a generic term for a combined low density, fiber reinforcedconcrete. SACON involves the substitution of a light-weight materialsuch as expanded polystyrene beads or preformed foamed air voids for thegravel aggregate. This is done to achieve densities of 30 to 90 pounds per3 cubic inch compared to conventional concrete at 150 pounds per cubicinch. This composition allows SACON to not only absorb bullets, but alsoshock waves that would be generated on light demolition ranges.

U Bullet Trap: Elastomeric Granular Screen

I Manufacturer: Societa FRA.SA.44 Via del GiordanoRome, Italy11-49-06-5924175

Method: Friction

Ballistics: 7.62 NATO and smaller

- Construction: This unique design is in the shape of a trapezoid of loose rubber granulescanted back at a natural angle of repose. Underneath this large pile ofrubber granules is a conveyor belt and support structure. Behind andbelow the conveyor is a sifting box and a vacuum system. The vacuum isconnected by piping that reaches up over the top of the trapezoid slope.

Capacity: Estimated to surpass 100,000 rounds before a substantial amount ofelastomeric granules need to be replenished.

Installation: Several weeks with the work being done by the vendor. Societa FRA.SAspecializes in modular indoor ranges that can be installed in two days witha trained crew and a cargo crane.

Maintenance: Daily operation of the conveyor/ sifter unit, requiring less than one hour ofdown time.

Description: When a round is fired at the sloping trap surface, the bullet penetrates therubber granules, loses velocity, and angles downward. The conveyormoves the very bottom layer of granules and projectiles rearward to asifter. Once the heavier projectiles have been removed the lighter granulesare vacuumed up to the top and dumped onto the face of the slope. Themanufacturer claims that the bullets are not deformed, and that a largenumber of them can be reloaded, resulting in substantial savings.

CONCLUSIONS

There are few unique bullet trap designs currently produced for outdoor ranges. A number ofindoor designs, such as the Passive Bullet Trap at the new NRA indoor range in theirheadquarters in Virginia, are quite innovative, but also quite expensive. Several majormanufacturers are modifying their most successful designs to operate in an outdoor setting. Mostcompanies who list themselves in trade publications or compendia, such as the Thomas Register,are really assemblers of other companies' materials or are target, not bullet trap, manufacturers.I Those who are true bullet trap manufacturers are few and do not advertise widely. Consequently,they are hard to discover. To date the market had been rather limited and not able to supportlarge numbers of manufacturers. Until recently, neither environmental concerns nor urbanI sprawl made it necessary to consider use of bullet traps. Most shooters could easily travel to anoutdoor range and fire into a berm or simply into the woods without much concern for theconsequences. Urban sprawl and heightened environmental awareness have now made the use ofI- bullet traps either desirable or necessary, thus attracting manufacturers into a previously smallmarket. In addition to domestic manufacturers, Canada, western Europe, eastern Europe,Scandinavia, Asia, Australia, and New Zealand were investigated as potential suppliers. Of theforeign countries investigated, only Germany, Italy and Switzerland had manufacturers. Some ofthe traps that have been investigated appear to be viable candidates for some applications onArmy outdoor small arms ranges. However, manufacturers performance claims should beverified by demonstration under operational conditions to provide objective data on the trapsability to contain or prevent the spread of heavy metals on the range as well as the durability,maintenance requirements, effects on training, life-cycle cost, and utility of these traps.

GranTrapTM Granular Rubber Bullet Trap

I The patented GranTrap granular rubber bullet trap was developed to meet the need for a cleaner andsafer environment in indoor and outdoor shooting ranges. The GranTrap allows bullets to pass throughthe rubber front panel and be captured intact in a chamber filled with GranTexTM!, a specially treatedI rubber granulate material manufactured from recycled materials. The bullets remain intact, eliminatingair borne lead dust and preventing lead and jacket backsplatter.

U The GranTrap is available in pistol and rifle versions and can be used in indoor or outdoor ranges.

The GranTrap Granular Rubber Bullet Trap is licensed and manufactured under U. S. Patentnumbers 5,171,020, 5,340,117 and other patents pending. GranTrap and GranTex are trade-marks of Caswell International Corporation

Range Masters, Inc. is dedicated to the design and construction of durable, cost effective products"to meet the needs of today's range owner. The need is now greater than ever for safe,environmentally sound ranges. Tighter governmental regulations on firearm generated lead willsoon end the practice of firing into outdoor earth berms. Indoor ranges with steel trap ranges, with

-i. their incredible amounts of generated lead waste, will not escape the closer scrutiny. To combatthese range threatening problems, Range Masters, Inc. has developed a new system.

At Range Masters, Inc. our ballistic team has developed a revolutionary new family of productscalled the TEC System. The TEC System, or Total Entrapment Composite, utilizes particles ofrubber recycled from tires bonded together with a synthetic agent, additionally reinforced with

iKevlar®. Using this composite and our various product designs, we are able to provide anunmatched range of use.

To achieve a ballistically safe range, only two things need to happen. The projectile must be

1 controlled and then contained. Regardless of the angle of fire, nothing can return toward theshooter or firing line. In all TEC System products, angle of fire has no effect. Additionally, no

I I portion of the projectile escapes containment to return toward the firing line.

lI Beyond ballistic safety, there is the risk of long term lead exposure in firing ranges. Whenprojectiles strike traditional steel traps, they shatter, causing dramatic increases in airborne lead.3 With any TEC System product, any lead is contained, blocking re-entry to the range. Indoors, an80% to 90% reduction of airborne lead can be achieved with TEC Systems. (Varies by style of

I i ammunition vs. steel traps.)

I i Besides safety aspects, there are additional benefits to using TEC System products. High amongthese is reduced costs, both in clean up expenses and replacement of lead contaminated equipment.iISince the composite absorbs and contains the lead, it does not create hazardous waste. This greatly3 reduces the exorbitant expenses involved with clean up of hazardous or toxic materials.Additionally, since concentrations of airborne lead are reduced, mechanical range equipment is less3 ilikely to become lead damaged. Greater mean time between replacement results in less fundingspent on replacement or maintenance.

II

Page 63: Bullet Catching Mechanisam

ii15 While TEC System products reduce costs, perhaps one of their premier assets is income generation.

Projectiles fired into and recovered from TEC System products can be resold to local primary

II smelting operations. Again, there is none of the regulatory problems of hazardous waste.

Ii Bullet Trap

jj RMI bullet traps offer the dependability and versatility demanded by modem shooting conditions.

ii The TEC System bullet trap is truly a bullet =.. The bullet is absorbed, unlike traditional steel

traps which merely create a ricochet. This absorption of the bullet is an important feature. It

1I permits the bullet to be decelerated with a considerable reduction in bullet fragmentation. The

extraordinary design of the RMI bullet trap offers a solution to several problems a range owner

II faces daily. Some of these problems are mechanical fail, lead build up, hollow point and steel core

ammunition usage, depth of trap, large components and complex equipment.

The RMI bullet trap uses no moving parts to trap or recover the bullets. An infallible system is

IIutilized to recover bullets... gravity. The bullets pass through the outer surface of the trap where

deceleration takes place. Without sufficient energy to re-enter the composite, the projectile then

falls through the channels inserted through the TEC System blocks to a recovery area. Unlike solid

rubber composites, these channels allow for expansion, due to the introduction of more projectiles.

ii Without room for expansion, projectiles will continue to mass bullets without relief In short order,

a dangerous situation can be reached, potentially causing fragmentation to return into the fire lanes.

! Due to the great variety of ammunition available to today's shooter, full control of what is fired may

not be achieved. Bullet traps must be able to provide safe containment no matter what typeammunition is used. RMI bullet traps accept hollow point and steel core bullets, without undue

wear, unlike steel traps that are rendered unsafe after limited uses of steel core bullets. Many

composite bullet traps use either hard rubber or plastic surfaces. These types are subject to rapid

deterioration when hollow point ammunition is used. Hollow point bullets are widely used in both

law enforcement and recreational shooting which account for a large portion of shooting in today's

l ranges.

Bullet trap depth is an important consideration when choosing range equipment. The RMI trap

requires approximately 30 inches of depth. This means a reduction in building construction and

Shoot House & Ballistic Panels

A split second is all you have to hit a moving target and a miss could cost you your life. This is a

real situation that law enforcement and military personnel face across the nation daily. The only

5 Iway to train for this type of shooting situation is realistic training. With this increasing need for

realistic live fire training, safety is paramount. Traditionally, live fire urban training was conducted

* in tire houses, wooden structures, and large outdoor ranges. These shooting environments all have

one thing in common - secondary missiles or ricochets!

Today, there is a solution to this serious and often life threatening condition. Range Masters, Inc.

offers several products to increase the safety of live fire training. The backbone of our product lineis the TEC System. The TEC System uses rubber particles from recycled tires bonded with a

1 synthetic agent and reinforced with Kevlar®. This product is not only cost effective, but also lessens

the ecological burden on the planet.

By utilizing the TEC System, the shooting environment can be customized to meet tactical training

3I requirements. One of the optional systems is sheet steel (ranging based on consumer specs from

mild to Brinell 500) faced with replaceable TEC System panels. This provides positive containment

* and increased safety.

The second option is our interlocking block system. This system employs a manageable solid block

that is simple to install. This is an important consideration when manpower is limited. With3 numerous configurations and the ability to create free standing walls, various training environments

can be used. Additionally, rubber composites, unlike wood, absorb great amounts of sound and

3 does not splinter. These are important factors when training requires a safe, durable product for

close orders training.IThe TEC System panels have been designed to meet several shooting requirements. The panels are

I produced under strict quality control. This allows for diverse product usage. The side wall panels

can be used for ground/floor covering. This will greatly increase the overall safety of the tactical

I shooting site.

I For conventional shooting situations, the panels are used to face baffles, safety ceilings, concrete

walls, and floors.

UOutdoor Ranges

From the time firearms were first used, outdoor ranges have been operated. Other than

U improvements in the areas of safety and back stops, most outdoor ranges have not changed.

I In most of today's outdoor ranges, the majority of back stops are still earth berms. Earth berms

must be periodically mined to recover lead. Earth backstops, though inexpensive to construct,

become costly over time. With the new increasing environmental pressures added to the rising cost

of professional recovery, earth back stops will soon be a thing of the past.

One of the major draw backs to the use of earth back stops is safety. Bullets will either ricochet

off or "roll over" the top of the back stop. There have been several attempts to curb these incidents

over the years. The only viable solution has been a shot fall zone! The large amount of land

I required for even 22 rimfire ammunition can easily exceed most project budgets.

I In the construction of range amenities wood, concrete and steel are used. These elements have

been for the most part used due to cost and availability. Today, range owners have a solution to

problems like wooden structures being decimated or law suits deriving from secondary missiles.

The TEC system products can be used to replace berms and earth back stops, RMI interlocking

blocks can be placed in a frame to fabricate free standing TEC walls. Interlocking blocks can be

used to retard erosion if your range currently contains a earth back stop. The TEC panels can be

I adhered to concrete or steel surfaces, allowing for the retro-fitting of most ranges.

I One of the most bothersome by products of firearm usage is sound. We offer various products and

techniques to conform to required sound levels. With the use of TEC system products, sound can

be channeled and absorbed. One of the techniques of sound abatement available are ribbed TEC

panels that can be adhered to the sides of wood or steel range dividers. Further, free standing

I walls can be cost effectively erected in problem areas to greatly reduce and channel sound down

range. If bench rests are used, we offer a portable sound suppression system that adjusts to

I standard bench rest height. This system will notably reduce the amount of sound exiting the range.

The suppression system is designed to absorb part of the sound and channel the remaining sound

waves down range. These inexpensive systems can increase shooting comfort while decreasing the

amount of sound exiting your range.

!3 Military Ranges

Range safety is one of a commander's most critical task in conducting any live fire exercise. RMI

clearly leads the industry in this area. All members of our research and design team have served in

the military and conducted range training for several years. With a vast amount of hands-on

3 experience we were able to develop products to meet the specific needs of military ranges.

11 M-16A2 ZERO Range

3 One of the most important elements in qualification is a properly zeroed weapon. With the addition

of RMI products your current zero range will become safer and have needed amenities.IIWith safety being the primary concern, we have developed a new baffle system which allows the

individual zeroing to acquire his/her target while restricting the elevation of their weapon. The

baffles are faced with TEC panels that, in the event of a misplaced shot, will absorb the projectile.III By replacing the front of existing earth back stops with a RMI modular bullet trap, there will be no

imbedded rounds or rock to create an unsafe training environment. By using baffles with the bullet

II 5trap, elevation can be controlled to keep rounds from being fired over the bullet trap.

Lane separators can be added at the firing line. The separators are designed to protect personnelfrom being struck by either brass or ground ricochet from a misguided round. An optional mat may

"-I 3 be placed between the lane separators. These mats will provide a non-slip surface and when placedon a slight grade permit water to drain away from the firing position.

To augment the RMI M-16A2 zero range we offer a revolutionary target holder. Our holders are

"- 3 constructed with a solid sheet of TEC system. The targets are simply stapled to the face of the

sheet. The holders reduce the projectiles velocity and thus, increase the durability of the bullet trap.ii The TEC system sheets are far more durable than wood or other similar materials. With increased

durability the overall cost of range operation is reduced.

The TOTAL CONTAINMENT TRAP (TCT) is simply the best overall solution for ranges where safety, reliability, lowmaintenance, and ease of use are top priorities. Action Target's TOTAL CONTAINMENT TRAP has overcome theproblems of other inferior designs which do not provide for close-distance shooting or for shooting with high powerrounds. The advanced design of the TCT uses a gracefully sloping funnel to safely direct rounds into a large chamberwhere they can be stopped with complete safety. The TCT can be safely used for handgun, shotgun, and most high power

S rounds, and is ideal on both indoor and outdoor ranges. The TCT is an independent, free-standing structure, so it can beinstalled with minimal preparation on nearly any range site.

The TCT's all-steel construction and funnelling action provide the only bullet containment and splatter protection yourrange will need. There are no costly, high-maintenance shields or curtains of any kind required. Remember, the "TotalContainment" concept means containment of bullets, containment of ricochet and splatter, and containment of ongoingrange maintenance expenses.

Once the bullets have been collected in the main chamber, a number of debris removal systems may be used to extractthe spent rounds. Such systems range fromsimple pull-out trays to fully automatedconveyor belt drives.
