Well known Alaska Peninsula outfitter Dick Gunlogson, retired now, and all of his bear guides carried .338 WM Model 70s and shot 300 grain Winchester ammo in preference to all other choices. Worked or im. I don't think the 300 grain is still available in factory ammo, but other bullets will do.. I like the .416 idea but I really think anything from .338 up will work if properly bulleted. BTW the .378 Waatherby is a bear thumper.
