I am a gun collector/hobbyist who is also a gamer. Guns and PC games have been a hobby of mine since I was a boy and I like them both equally. I like the fact that Arma bases the damage of it's weapon on the round and not the gun itself although barrel length/no. of twists does have a slight effect on accuracy and velocity, but I digress. Any round from the .22 short to the .50 BMG has the potential to kill with one shot. Now the flip side to this is the fact that this a game, albeit one attempting to be as realistic as possible. I do feel that the handguns should be tweaked up a bit for damage and down for accuracy. A handgun is rarely effective beyond maybe 25m in a combat scenario. I'm not sure how many here have used a handgun extensively but it is challenging to fire under perfect conditions, much less combat. But, you catch a round in the vitals or the head you aren't going to be a happy camper. Shot placement is everything. Check out the FBI report on terminal ballistics, interesting read for those who want a down and dirty lesson on the subject. Overall, I think the damage is fairly well represented in Dayz. There are a couple of gripes I have though. I'm not sure why there is significant difference in damage between 5.56x45, 5.45x39 and 7.62x39. As far as terminal ballistics are concerned these are very similar. I have fired all three in many types of weapons (5.45x39 in an AK74 is my favorite). 5.56 is the most accurate but that could just be the M16 platform, it also shoots a bit flatter than the 5.45 and a lot flatter than the 7.62. The modern 5.56 NATO round has probably about 100m more effective range than the other two. Ironically the 5.45x39 may be the most deadly type of round if you consider the original bullet for the AK74 had a hollow space under the jacket (not to be confused with a hollow point). This would cause the bullet to disintegrate on impact causing a devastating wound channel prone to infection. The Mujahadeen fighting the Russians in Afganistan called it the "poison bullet" because of this. I think the damage for the 7.62 class of weapons is just about perfect. Head or chest, done. Legs, broken and useless. There is a reason US special forces brought the M14 back into service as a a combat rifle. I have mixed feelings about the .50 BMG rifles in the game since they do have a place as anti-material rifles but they are so rare in the military that I could never see them finding their way into the hands of a post apocolyptic survivor. In a unit of thousands there may be 2-4 of these rifles in use. Have any of you ever actually seen or held an M82/M107? Just walking around with that thing would be a challenge, much less running. They are realistic in the sense you can use them to great effect against people but the mobility/rarity of them in a real scenario makes me question their validity in the game. I like the suggestions for including .338 Lapua which is a very powerful round similar to the .50 BMG in ballistics. But again, very rare in the military (the Brits use it) and rarer still for civilians. I do like Rocket's comment about adding more civilian weapons in the SA game. Makes sense to me. Yes, I have a collection of real guns. Yes, I was an active duty US Marine which is where I was able to handle and fire a lot of US and other weapons during my career. No, you shouldn't take my opinons as fact. No, a game cannot be absolutely realistic. It still needs to be fun, real life is often no fun at all. Sorry for the winded post but I really enjoy this game. Thought I'd add my opinion to the topic.
