I have had a place on the Kenai for years and one of my brothers has been stationed @ Ft. Rich for the past decade...we have hunted pretty much everything that moves up there for about 20 years now and both of us use .300 Win Mag with 180g Nosler Partitions...haven't found anything it won't kill and it is the perfect combo of light and accurate and easy on the shoulder. Both of our pre-64 Winny's have taken moose, brown and black bear and caribou. His wife also uses a .300 Win Mag as well and has been equally successful. One doesn't need a 375 or 416 to hunt up there.
