If I was going for wolves I would most likely take my .243 or my .25-06. No doubt in my mind that either wouldn't smash a wolf. Take what whatever gun you're most comfortable with and smoke a pack of 'em! Good luck man. I hope you guys get a few!
They've killed wolves in Idaho with .223's this year. That guy that shot 2 called them in then shot the pair with his .223. My point is that anything you're going to use for deer would work....just depends on how much damage you want to do to the hide as Shirtguy mentioned.
