I think going from a 270 winchester to a 300 WSM or a regualr 300 winmag is a good choice based on your listed game species. (Although I’d stick with the 270 for caribou and black bear)I would advise you to check out what kinds of bullets are available in factory loads, the longer 300 winmag in general handles the very heavy bullets, and you definately want 220 grain for grizz, 220 and 200 are gonig to be good for moose. I haven’t looked at the entire line of 300 WSM recently but last time I did they only offered bullets of weight range 150-180I’d recommend the Sako, they have a great reputation for producing consistently accurate production rifles, and with the A7 accuracy guarntee, you should be golden. I just don’t have much experience with the browning Abolt to recommend it.Active member, Defenders of Wildlife
