RE: What do you use a .22 for?
Since I carry a 22 with me almost everyday, it has seen lots of use. I've dispatched deer with it (local game warden calls me when they get stuck in fences and he doesn't want to drive 60 miles out of his way to dispatch them), coons, skunks, porcupines, coyotes, badgers, fox, gophers, rabbits, mink, muskrat, beaver, woodchuck, snakes, birds, and everything else that lives in South Dakota.
People who say it won't kill obviously aren't shooting the right ammo, or aiming at the proper spots.
