I'd suggest your friend treat the Old Army like it's a bow, keep shots close (say 25 yards or a bit more) and shoot only when you have the perfect shot placement. If he's experienced hunting hogs, he'll know how to kill them and should not have a problem. Unlike the bow, he's got a fast second shot in case piggie runs right at him.

Sounds like fun to me! Good luck, have contemplated the same thing myself.
