Live up in Alaska and I'm new to LRS and want to buy a new rifle for. Long distance hunting. My hunting partner is getting a 30-378 Weatherby and I'm thinking about a 300RUM or 338RUM. I'm kinda leaning towards the 338RUM because of the barrel life of 300RUM. I've heard you get better barrel life out of the 338RUM. Any suggestions would be nice And thanks.
