I highly recommend the 338 RCM in Rugers compact platform.I found a left hand version and have been using it for about a year now. So far I've taken a big bull bison, a caribou, and a wolf. I have access to one small sporting goods store and have had zero problems getting brass. I have enough hoarded away now to last as long as I will be hunting. I cant imagine a better all around caliber for big game.
