I started out with a .223 and it was a tack driver, but kind of turned sour when I had 3 animals, coyote, 2 hogs, knocked down, but they got back up and ran off, at only 100 yards distance.
Fluke, or my bad shooting I don't know, but I've since gone with the .357 Max, and my 45-70 and they've performed well, and so far nothing has gotten back up and run off!
