I'd say since you don't reload, forget about the 35 Whelen. Factory ammo is not common and I would not want to rely on ordering ammo off the internet. I'd say for the non handloader, 30-06, 300 win mag, 338 win mag and 375 H&H are the best choices for Alaska in terms of terminal performance and over the counter ammo.
And I say this as a big fan of 35's having had a 35 whelen, 350 Rigby and now a 350 rem mag. But I've always fed them handloads.
