At the range recently I was told about using a 180 gr .358 Sierra slug in a .357TC Contender for a deer hunting round. I'm somewhat skeptical. Sounds like a knuckle buster to me. Something about putting a .358 slug down a .357 bore turns me off. I used to shoot IHMSA with a 170 gr .357 but never had the thrill of trying a .358 bullet. Any comments about this would be helpful.
