I have a 300 Win Mag that has about 900 rounds through the barrel. It shot ok, holding about 1 MOA in short and mid-range distances, but I never was able to get it to shoot really well (~1/2 MOA CONSISTENTLY), so I'm thinking of rechambering. This will be my long range hunting rifle and I will use it for deer, elk, caribou, moose, bear, etc. I'm not looking for any more recoil by going to a 34 caliber bullet and would like to stick to 30 cal or less, though I know I'm really narrowing myself to somewhere from .277 to .308. More exciting to think about are the different case configurations one can go with. What would you do? Rebarrel with 300 Win Mag, or, take the opportunity to rebarrel and rechamber?
