I have never shot at a hog but this is a very interesting thread. It would seem that a hog is some kind of armored pig and you really need an anti-tank gun to kill one. Yet other posters say a 22LR inside the ear canal will work. I'm confused, but this sure is entertaining! I carry a GP-100 as a woods gun with 125gr JHPs from Black Hills, but it's not for hunting. It just seems that if a .357 will go through a drivers side door, then through a passenger side door but won't go through a hog??? It makes my head hurt thinking about it.
