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

JBM Ballistics offers a simplistic conversion tool, free of use (https://jbmballistics.com/cgi-bin/jbmgf-5.1.cgi).

However, the AtragMX will only accept a bullet’s coefficient if it is G1 (a close enough approximation to C1). Most non-ACE ammos in the game will only display G7 coefficient; in this case, do a conversion using JBM Drag coefficient conversion.

For C1 Coefficient when manually entering a new bullet type not already in the AtragMX Gun List, you will need to open any arsenal to select the bullet and check the coefficient in the top left corner.

C1 coefficient doesn't need to be changed if you have copied the statistics by apply an ammo type from the Gun List.
