I agree with 300,, if a shotgun is legal, carry some slugs or 00 buckshot, if that is legal in your area. If you bowhunt, take that. I broken many a cedar arrow loosing them at tree-rats with my longbow. Kill several a year that way,, just try and wait until they are on the ground,, dirt is not as hard on arrows as hickory trees. A quatering away shot, low in the heart area with a sharp broadhead, takes hogs down after a short run many times. Hogs are very good quarry for stalking, just watch the wind.
