All around fun/critter gun besides a 22lr?

221 Remington Fireball if you do not need to push it beyond 200 yards or so.

17s are fun.

cfullgraf, you can stretch a 221 Fireball out beyond 200 yards with light weight bullets. Pretty much have to reload for it though as you don't see ammo on the shelves very often and when you do it's expensive. Pretty cheap to load for. I even make my own brass from military 223. I've had mine since 2007, what a fun gun to shoot.
