Does no back-up include pepper spray? Considering a Alaska hunt will only happen once or twice in my life most likely if I'm fortunate, I think I would go with the model 70, 300WSM. I currently own one(my largest caliber) and originally bought it to make sure it would be suitable for game up to elk and maybe a potential Alaska hunt. At the time I had no other rifles. However, if I ever do go to Alaska, I wouldn't rule out getting a 375H&H, just because I can, and then I would have, something for Africa, in case that ever happens. Alas, this is not your question. 300WSM with 200gr. Accubond while in Alaska. In the lower 48 I would use different bullet weight, probably 180's on everything, probably Accubond, although I'm thinking about the 190ABLR, just because I have no desire to buy extra ammo and continually re-sight in rifle. But I wouldn't argue against a 300 or 338win mag.
