I have found that it has some weird issues with the way sounds are modeled. Having shot a large variety of older military weapons in various calibers and been down range on long range firing at targets the sounds seem off somehow. Also some hunting weapons that use similar calibers to the ones depicted in ArmA3 (6.5mm) they really don't sound like what I am hearing in game. It is something that I can't quite put my finger on for this and I am not sure why. I want to help make this work a little better and would like to have the opportunity to help out if you need it.
