I've killed 2 grizzly bears in AK. One was with a 375 Ruger & the other with a 30/06. Both were 1 shot killls. I've killed everything else in the lower 48------from moose to antelope and everything in between with a 30/06. When grizzly are in the mix-----I would not put the 30/06 there.

IMO---the 30/06 in AK, it didn't give me the confidence in it. 375 Ruger was OK. If I lived there permanent And grizzly/brown bears were in the mix----I would pick a 300 Win Mag. It shoots flat enough for goats & sheep. It's perfect for moose. Caribou are pretty easy to kill. A 200 grain Nolser partition will handle a grizzly.
