Maybe a little off topic, but I do know that when we were slaughtering hogs, we forgot a .22, and all I had without going to the house was my .38, with aluminum defense rounds...not a good idear from my experience...5 shots right where they needed to be, and 1 really irritated hog, went to the house, and got the .22, dropped it with one shot, in the same place...and that was some nasty tough pig...
