The other aspect not yet mentioned; I feel much better walking through grizzly country with a 300win on my shoulder than a 308win.
I would prefer the right bullet and a 308 for under 50 yard shot at a grizz. to a 300 Win. Penetration and bullet integrity versus velocity. And a lighter handier rifle.
Not to mention less muzzle flip/recoil (getting back on target for the shot), and greater magazine capacity.
All my hunting is in grizzly country... I'm perfectly at ease with the 308, 7-08, 270, etc...
