Okay John...Of the Hunting rifles I own and shoot game with from the .270 Win(two of them)to the mighty 375 H&H Mag...My choice for Idaho hunting is the .300 Win Mag.

The .264 Win Mag is a fine caliber.One of my good friends in Riggins Idaho takes an Elk most years off the Hells Canyon Breaks(7-Devils area) with it although,I don't see much difference in immediate effect than a 270 Win,but both are excellent calibers if the nut behind the scope does his part.
