Crap, the guy couldn't hit you at that range BEFORE you chest hit him with 223, if you were sensibly using cover. A bobbing head at 300m is an impossible shot, for other than pure luck. Maybe YOU are stupid enough to leave your head exposed for more than 1 second at a time, but no truly dangerous man is going to do so. So the dipshit flops around for a minute before he bleeds out from the 223 hit, so what? he's no threat to you. The further away he is, the less of a threat he is, once wounded. Maybe YOU are stupid enough to run right out there to take his scalp, etc, but I aint.
