I've applied the drag for APDS and SLAP rounds config. It's invaluable, thanks!

However this source:
http://en.wikipedia.org/wiki/.408_Cheyenne_Tactical

States the .408 has really low BC. I tried to match the air friction so bullet shot with init speed of 930 m/s keeps supersonic up to 2200 meters.

Hmmm, when I use airFriction = -0.00042 (or thereabouts) with initSpeed 930, the bullet still appears to be supersonic at more than 2,200 meters (calculated ArmA velocity of *about* 366 m/s at 2,200 meters).

The initSpeed in the current config is 910 m/s, it is also supersonic @ 2,200 meters with that muzzle velocity.

Going to review .408 once again. Thanks for input!

While this is over my head, still upvoted because I want realistic ballistics!

Thanks for the hard work!

I have added an explanation on forums (see http://forums.bistudio.com/showthread.php?155971-Sniper-bullets-have-unrealistically-low-aerodynamic-drag&p=2408475&viewfull=1#post2408475) - this has been done for gameplay sake and there is just a slight chance we would be able to fix that for release of the game, because it would break the game balance otherwise.

There have been improvements in this way on engine side that made real values usable in game. Could you, please, confirm the fix and close the issue?

Checked, airFriction values have now been set to appropriate values (26/06/2013). Good work!
