With the changes in muzzle velocity alot of the current weapon damage has decreased slightly. Most notably is the fact that with a 6.5mm or lower you can shoot someone directly in the face point blank and they will not die in one shot.
Well hopefully they fix the head shots so it's realistic only being one shot to the head. But I don't know if anyone else has heard the 7.62mm rifles suppressed sound when firing? A rahim with a suppresor sounds so nice, you can even hear the distinctive sound of a cartridge being ejected from the rife. Then again i suppose everyone has heard it, this is Altis after all everyone has a gun here
