RE: Shotgun for Hog
SMALL GAME & FURBEARER FIREARMS:
Rifles and Handguns: Any .22-cal. or smaller
rimfire, air rifle, or any muzzleloading firearm.
Shotguns: Any having shot shell size 3.5
inches or smaller in length with No. 2 or
smaller shot.
Sounds like a great chance to use a smokepole if you have one. A .50cal conical or sabot slug being pushed by 100gr of powder would put any hog down pretty certainly.
