Raccoons. I shot a groundhog last year with .22 Thunderbolts. First shot to neck didn't kill it. Second to head did but it took about .30 seconds.

Last year, I shot a squirrel to put it out of its misery. Eye was hanging out and the flies were already on it. First shot to middle of body from 5 feet. Jumped but not dead. Second to right under armpit and it curled up and was surely dying, but still not dead. Third shot nearly point black to head and it was done.

I'm not a hunter. I have no wish to kill anything. Somebody must be feeding these raccoons because it came right up the the door and started pawing at the screen. I popped it in the butt was a BB gun that was almost out of CO2 and it wandered off. It was only about 6:15, too. Never seen them out that early.
