Never hunted grizzly or Alaska, have only killed one bear and that was a black bear shot in his left eye at less than 20 yards while bow hunting elk, were I to go after big bears and recoil was a concern, I'd load one of my '06's like a baby 375 H&H mag, that load would be an easy to shoot 220gr Partition at 2500 fps, I would be surprised if any bear could contain that load.
