When I was growing up in the 1980s, Alaska was flush with oil money. This is early 80s. We used to go on school trips for two to three weeks at a time. I figured out that a hamburger was a pretty hard dish to monkey up. You could even go to a Chinese restaurant or a sushi place and ask for a hamburger and they won't monkey it up. I have been wrong a few times. But in my view, a 30 government 06 is a pretty tough rifle caliber to monkey up. You could do it but you have to try. Up here in the pucker brush a 6.5 creedmoor is basically an appetite stimulator for a large brown bear. Sure, you can show me a picture of some dude hunter in Kuiu holding his magical mojo chassis rifle in the manbun but I'd like to see the same feller in deep brush with a bloody deer on this back in 0 dark thirty. Nope. Nope. Nope. 06 is great in this gun.
I had an old neighbor who during the war years had a .270 that he used to hunt bear in Alaska with. I believe the .270 would of been fairly new at the time. If the .270 can do it the 30-06 can do it better. Especially in Alaska as you say. The 6.5 manbun just seems to be a bit under powered for what's hiding in an Alaska forest, especially after dark.
