OK, I am soliciting opinions. I have a Winchester M70 Classic Stainless in .300 Win Mag w/BOSS. I am going to have a custom rifle built on the action. I have a custom 300WSM for my sheep,moose, caribou, etc. rifle. Need something for bears, but lightweight. Toying with anything from a .338 to a ????. I have a .375 Weatherby and like it, but it's a push feed and heavier than ##$%. Suggestion?
