Ah the smell of hot metal and burning powder. If anyone ever wants to give me cologne find Eau Du Firing( joke I'm not that big of a gun geek)alex_greene said:If there is autofire, assume between 60% to 90% of the rounds fired would miss and impact on surfaces such as walls, go through windows, smash through car windscreens and door panels, ricochet off harder surfaces such as stone and so on. So after the gunfight, you'd see a lot of bullet holes and pits, lots of glass fragments glittering all over the floor, maybe a fire hydrant geysering a fountain of water and something on fire.
And everywhere would just reek of burned black powder.
If anything yer being very generous on how many rounds hit something other than air, or the ground.

the few times I have had a chance to fire an automatic weapon the sheer number of wasted rounds was impressive. I'm pretty good with a pistol or rifle. but dern, I wasted a lot of rounds.
even the fellow who had decent training with the weapon only managed a few hits with each burst everything else went into the backstop.
An SMG/carbine/assault rifle is likely to produce an impressive number of holes in the wall but it's not much good unless someone has a good deal of training and experience with automatic weapons.Unless Murphy or Karma are involved...those two never miss.
