Personally I would think a .357 is a little light for hogs. We hunt them all year long and we've shot a few that were wounded w/ a .40 S&W and it took a couple of shots to the head to drop them and that was from close range. If you run into a large boar they develop a thick shield over their shoulders and it takes a heavy bullet to penetrate through it. We've shot several that were full of scars on their shoulders where they were shot before and survived and healed up. The shield can act almost like a bullet trap if you don't hit them right.
