do you CARE if a guy flops around for 20 seconds or so out there, before he bleeds out (223 hit), hmm? He can't hit you from there, after taking such a chest hit. Unless you are stupid enough to run right out there, he's no longer any concern to you. The wt and bulk and NOISE of 308, lack of .22lr conversion, will ALWAYS be a concern., You lug it and you lug it, and the extra fatique makes you more prone to error, illness, injury.
