Old Winchester 1890 in .22 WRF, don't shoot it that often anymore (have to drive 40 miles or go to the internet for ammo) but my dad used to have a couple hundred rounds laying around. Never shot from the bench or anything, but I never missed a Gray Squirrel. Accomplished some pretty gory headshots while crouching.

Nowadays it's my Savage 111 in .270. I never use a stand or a rest or anything so I usually get 1 - 2 MOA at the range depending on how I'm feeling. Not as accurate as the Winchester, but the trigger pull and the rifle itself is far heavier.
