ATragMX setup: C1 ballistic coefficient
Ballistic coefficient is a measure of how easily a bullet cuts through the air. This metric is critical for precisely calculating the arc of a bullet in flight.
To find C1 ballistic coefficient, open the arsenal and select the desired bullet. With the ammunition highlighted, the ballistic coefficient will be displayed in the top left corner, alongside other bullet information.
Note: although G1 coefficient (displayed in arsenal) and C1 coefficient (displayed in ATragMX) are essentially identical, if the arsenal displays a G7 ballistic coefficient, this must be converted using an online calculator.
G7 to G1/C1 Conversion
To convert a provided G7 ballistic coefficient to a G1 or C1 format, you will need to collect information from your range card or the arsenal:
- Bullet caliber
- Bullet weight
- Muzzle velocity
