Ruger M 77 mk II s are hands down my favorite rifles and about the only action I truly trust. I regret building my 9.3x64 Brenneke on a Mauser action.
Alaska is very hard on rifles and it's a great place for the controlled feed Ruger's. .
One of the worst things Ruger never did was make a magnum length stainless action so It could house the 375 H+H and 416 Remington. But they did come out with the 375 +416 Ruger's which almost makes up for that.
