Kind of a weird question... obviously, if there is no ability to buy bullets ever again, and you have to pick one weapon to survive the rest of your and your family' s lives, you have to pick a bow - only thing with reuseable ammo. If civilization ended today, though, my family would have three muzzleloaders with ammo for probably 50+ kills, 6 ' deer killing' rifles with ammo for 600+ kills, .22s to kill about 10,000 squirrels, three 12 gauges for 50+ kills (deer) and 25+ kills (bird/squirrel), and a 20 gauge for 25 kills... before we had to break out the bows. I think that would make us pretty old. [8D]
