I'd say get a good used Marlin 30-30, and a box of Remington Core Lokts for about $9/20. Be alot more useful for shooting hogs, and fairly inexpensive as well.

I have a few 22mags, and I wouldn't want to piss off a hog or make a marginal shot on one. Coyotes are tough to bring down with the 22 mag, so I'm assuming a hog would be alot tougher.
