everyone that you HAVE to shoot, and 80 rds of 223 is going to go a LONG ways, dude. By the time you fire 100 rds of 22lr at PEOPLE, and even 40 rds of 223, you are either going to be dead, or you will have scores of guns and hundreds, if not thousands of rds of ammo, to retreive from the dead. Lots of that is going to be .22lr, and a fair amount of it is going to be 223. You only have to hide-fight for a year, and it will all be calmed down, a LOT, one way or another. So much for "needing" lots of rounds. If you are stupid, have no .22 unit, no silencer, no ccw'able rifle, and don't take advantage of darkness or thick cover, being mobile, using snares, nets, etc, and "think" you have to fire at everyone you see, at any range, "thru" cover,ALL animals, etc, yes, you need lots of ammo, and you are STILL going to die early-on, because you are STUPIDLY bucking the odds, when you don't HAVE to do so.
