Let's see, Ive take ground squirrls, tree squirrels, ground hogs and coyote - I shot a pig once and put it down - That would have been the biggest. it was about 400 lbs on the hoof but it was a domestic (HA!) pig. Darn thing just about took my leg off. It was shot at 35 yards through the head and fell where he was stopped, staring at me.

I was gonna try it on a range bull but thought better of it when he wasn't impressed with the noise it made the first time.
