Re: .338 Edge bbl life
About 350 rounds through my edge and there is no visible errosion or major heat checking when looking through the bore scope. Then again, I dont hot rod her or even run top loads. I dont shoot too many rounds in a string either. After burning out 2 300 RUM barrels, I find the 338 Edge to be a welcome round. Hits harder at LR to boot. I dont care what others say, the 7 RUM boasts a very short life even if it is glorious. 500 rounds is a pretty good life for it.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
