I've never hunted the big bears either....But I do know that if I won the lottery I wouldn't be running out to buy a new super big magnum. I have 30.06, 338.06 and 7 mag. I don't like recoil any bigger than those and would have a hard time practicing with a 340 wby etc. I've killed plenty of game with my rifles and feel very comfortable with them. I'd take one of those after having had a conversation about it with the outfitter.
