I don't see why a .357 wouldn't stop a hog, if, like any other caliber used, shot placement it top priority. As I live up north, I have only shot 1 hog (in Florida), and it was with a 40+ year old Bear 50# recurve and a 2 blade 125 broadhead on a carbon arrow. Don't under underestimate any weapon if you do your part. IMHO, a .357 will be fine.
