Hornady has some sub sonic that are supposed to expand too but I have no first hand knowledge of them.

I only run supers. My backpack gun with a 10.3" Ballistic Advantage barrel which stays in the car/truck, is loaded with Barnes 110gr Vor-Tx. I shot a 6x6 elk with it recently. It was a mercy kill on an old animal and was sickly. At 30 yards quartering away, I aimed a little too far back and believe I got more lung than anything. The bullet did not go thru, the elk buckled, trotted about 25 yards, stood still for about 10 seconds and then fell over. When I flipped him over to check for an exit hole, I about gagged. There was a volleyball sized cyst that was cracked open. I'm surprised it wasn't maggot infested. While curious what the chest cavity looked like, I didn't want to cut him open.

For self defense, I think I'm good with what I got.
