**Game Version number:** 1.4.0.48 **Modded?:** No **Issue Description:** The "air drag" parameter on the "Ammo_762x51_Ball_M80" is unrealistically low at -0.0000083 with a mass of 0.00953. This results in the M80 ball having a velocity loss almost identical to the "Ammo_762x51_Ball_M118", which has an air drag of -0.0000097 with a mass of 0.0112. To make the numbers more clear, this can be translated into "airFrictions" as used in ARMA 3, by multiplying the "air drag" by the "mass": Ammo_762x51_Ball_M80: -0.00087 Ammo_762x51_Ball_M118: -0.000866 This is identical performance. But in real life the M80 ball performs significantly worse. M80 is light ball, and the M118 is a heavy match or sniper load. In real life the M80 ball has a ballistic coefficient of about **0.200 G7**, and the M118 ball has a ballistic coefficient of about **0.239 G7** (McCoy, Robert L. //Modern Exterior Ballistics. 2nd Ed// (2012): 104-105, 113, 175-176). This difference means in real life the M118 ball will have about 23% more energy at 600 metres. Based on the information above, the M80 ball in Reforger should have an "air drag" parameter of about -0.00000953.
