you're missing something basic here. i'm not aware of very many types of hunting in which there are not limits on magazine capacities. if we're talking c/f rifles i assume we're talking large furred game. i don't think there's any hunting of such which does not require a 5 rd magazine. so what exactly is the difference between an fal w/ a 5 rd magazine and a remington 742? the answer is none other than cosmetics.

likewise, i doubt you're going to ever be sharing a duck blind w/ anyone w/ a 15 rd capacity shotgun for the same reason.

in the hunting field, the firepower of said weapons isn't even an issue because it won't be there - legally.
