I wouldn't reccomend taking the 22mag on a pig hunt but i have taken decent sized ones with the 22mag. However you can't kill them as consistently for very far. I would limit my shots on a hundred twenty pound pig to about 40 yards. It goes without saying that you need to shoot them in the head preferably the ear or eye. The pigs that I hunt are russians that got loose about ten years ago. I know that these are easier to kill than some trul;y wild pigs. I also hunt from a tree most of the time. I am a fan of head shots and believe that if its at or under a hundred yards you should try for a head shot.Maybe I am a little crazy
