I'd be just fine with a 30/06 and 200 PTs. They are amazing bullets and when pushed along at 2600 or so would do real well I'd guess. Good luck hurting one of them. I've seen 300 Weatherbys not hurt them too awful much in my Bullet tests and recovered bullets out of dirt and rocks. I would be okay if that was what I was hunting them with. Same for the 200 AB. Both of those two are serious bullets for heavy, big boned game.
