Angle Shooting
Angle Shooting
•Gravity’s effect on the bullet is only equal to the FLAT GROUND DISTANCE
•When engaging targets from angles, the impact of the round will be high if you use the STRAIGHT LINE DISTANCE zero on your rifle
SHOOTER
TARGET
FLAT GROUND DISTANCE
STRAIGHT LINE
DISTANCE
• Range Estimation
– Straight Line Distance
– Flat Ground Distance
• Target Angle (up or down)
FACTORS THAT DETERMINE DISTANCE FOR ANGLE SHOOTING
It is important to understand that as the angle to the target increases the effect of gravity decreases.
• Map Relation• Cosine Formula• Vertical MIL Reading Formula• Pythagorean Theorem• Protractor Formula
Techniques and Formulas
• The most simple to use• Determine your location and the targets location• Plot both locations on a map• Measure the distance between points• This is your “flat ground” distance
MAP RELATION
• Straight Line Distance• Target Angle• Cosine Chart• Distance X Cosine = Actual Distance
COSINE FORMULA
• Clinometers / Ranger Silva Compass• Standard Map Protractor• Laser Range finder
BASIC METHODS TO FIND THE ANGLE
SILVA COMPASS
PROTRACTOR METHOD
COSINE CHART
EXAMPLES
• 1. 600 yds @ 30 deg =
• 2. 600 yds @ 45 deg =
• 3. 500 yds @ 40 deg =
• 4. 400 yds @ 25 deg =
• 5. 300 yds @ 40 deg =
.70 so (600 x .70)= 420 Yards
.78 so (500 x .78)= 390 Yards
.90 so (400 x .90)= 360 Yards
.78 so (300 x .78)= 234 Yards
.86 so (600 x .86)= 516 Yards
