I just did a quick check of 10 Alaska brown bear guides. Their recommendations were: 1. 30-06 1..300wm or 375 H & H 2. 375 H & H 6. 338wm and up
Look at the information on the Alaska Fish and Game website. It's about as good of advice as you will get. The right gun is the one you shoot best. Period. Magnums are not needed. Period. Nothing wrong with them either, if you can shoot them. I couldnt begin to tell you how many bull moose and grizzly bears Ive seen killed quite handily with a 30-30 Winchester. I've personally killed 4 woods bison now. One at 300 yards with a 338 federal. Seeing that the bison are the largest heaviest boned animals in the country I reckon that stretched out 308 will work for about anything.
