First, how much difference in barrel life is there going to be between a 300 RUM and the 338 Edge? I am going to buy/order a new rifle in one of these calibers and am torn between the two. Also, where do you get dies for the EDGE and how hard is it to keep the brass accurate/consistent since it is made from 300 brass? I have never had a rifle that you couldn't buy off the shelf dies and brass for and I don't want to get in over my head with the EDGE. Any info would be appreciated.
