I have been to places - including those occupied by hippos and elephants, with occasional nightly visits of lions in the tents.
Round of choice in all those National Parks was the 60,000 PSI .458 Win Mag with 500gr solids, flying above 2000 FPS.
Even a very stout 10mm with hardcasts is a challenge on Grizzlies, and you will have to make up with that 15 plus round magazine and hope the animal doesn't get to you.
10mm is decent in the lower states. In Alaska, I'd indeed carry a .500 revolver.
