RE: Moose Bear Combo Gun??
Been up to Newfy twice for moose. For whatever it's worth, the most popular caliber used by the locals is .308 Win. Second is the .303 Brit. You really don't need any more than that. I used a .338 Win Mag, and dropped two moose like the Hammer of Thor. I found that most shots that were takenwere in the 100 yard or closer range, and when I go again, and I will, I am going to use my Ruger #3 in 45-70.
Hope this info helps.
