Thank you very much for this!!! I've been up in your neck of the woods once on a brown bear hunt and can't wait to come back again....beautiful country!! I'm going to be buying a Blaser R8 375 H&H and will bring that or my Mauser 9.3x62 as I think either would work well.
Sounds good, and if you think you will have a little spare time while in Anchorage, give me a shout.
As for your rifle ideas, they sound pretty workable.
Lately, live ammunition for the 9.3x62 is becoming more common on store shelves here as time goes along.
But, ammunition for the .375 is still much more available in Alaska, especially farther out from Anchorage (Kodiak, King Salmon, Cold Bay, Sitka, Skagway, Etc), in case the baggage apes loose your luggage with your ammunition in it.
I prefer turn bolt rifles, such as the ‘98 Mauser and some of its descendants.
Not sure if Winchester still makes their stainless / synthetic Model 70 in .375 any more.
But if they do, it seems as if it’d be as close to perfect for coastal Alaska conditions as I could imagine.
However, you have mentioned the Blaser straight pull type rifle.
My understanding is that, Blaser has by now worked out the reported issues with the breach bolt, of those particular rifles, sometimes failing to lock up properly.
So, even though I definitely favor the much older turn bolt design in rifle mechanisms, nonetheless it is not my hunt, it is yours.
And, your idea of getting one of the newer model straight pull rifles, in caliber .375 H&H will likely work out just fine.
They are reportedly very accurate.
If whatever rifle you bring is not especially corrosion resistant (as is the case with every rifle and shotgun I own), common Vaseline is what I have had my best luck with, in keeping rust away.
In super cold weather, it can freeze solid (ask me how I know lol) so, I have learned to use it sparingly.
Anyway,
Cheers.
