I think the article is another infovertisenent. To sell rifles.

Never hunted Alaska. Have hunted Norway and Sweden. With borrowed rifles. ErikD loaned me his 7x64 Mauser M03 Extreme model. Plastic stock. Sville loaned me his double rifle in 9.3x74R. Maybe I carried his Blaster .308 once as well?

For Alaska, I would choose my Mauser M03 Extreme in 8x68S and .404 barrels. Maybe take the walnut stock Alpine model M03 as well if two rifles were needed.

I would love to use a .375 Flanged double rifle there. Don't have one. Yet.

Have to work on the .404 one-day with lighter pointed bullets to see what sort of ranges it could handle for medium game. I have some 257 grain projectiles I have never used.
