Only went to Alaska three times and used the following handgun
bullets: black bear- 300gr Partition from 454
moose- 300gr Punch from 44
brown bear- 360gr Corbon Penetrator from 454
The black dropped dead at the shot... the moose took the Punch through the lungs plus one from 375 H&H up the rear as he ran away that failed (bent) . The brown was not to big and took one through the lungs at 50... Any one the the animals you list can take a beating and a big Alaskan moose, black or brown bear would call for the 300 or 325 Swift from your 454....
