I currently own a Winchester M70 in 30-06 and I am quite comfortable carrying/firing it. I want a second big game rifle for Alaska and would like to hear some of your opinions. At this point I am leaning towards a .300 Win Mag but have considered going larger and purchasing a .375 Ruger or .375 H&H. This rifle would be used for moose, sheep, goat and brown bear.
...........Your 1st choice in cartridge should depend on what game you are hunting at the time.
Imo, and since you already own a 30-06, I see little benefit in acquiring a 300 Win.
Simple solution if it were me given the rounds you mention;
For big bears and moose, either the 375 Ruger or H&H as the 1st choice.
Sheep and goats, the 30-06 as the 1st choice.
