has it ever occured to any of you that the military, may not always try and kill a target with one shot, a .50 round from the m82a1/2 would put a big enough hole in any one that they would die almost in an instant, weather the bullet killed them or they bled to death, But that is not the point since war is a lot more cruel than you might think. Why do you think they use fmj bullets as standard issue, besides the obvious fmj pass through the body not causing as much damage as say a hollow point, thus wounding your enemy and causing your enemy to use extra resources in retrieving and treating that wounded soldier, just killing your enemy in one shot is easy, we have the guns to do it, but if you wound one others have to help and this gives you the opportunity to wound many others, no one is going to waste time to rescue a corpse on a battle field while fighting is going on, but if some one is screaming in agony, well you get the point...someone put a post of a web site in this thread that had a marine corp sniper training video it was pretty decent, they mention 4 types of ammo for the M82a1 and 2 of the 4 could penetrate light armour and one of them called a slap round could penatrate medium armour and explode the trainer never mentioned the gun was used on human targets probably because of the reason i stated above, unless you mean a specific target that you absolutly had to kill in one shot, you would probably not use the m82a1.
