I have a Ruger .338 that I bought back in the mid 80s, its blue the original wood stock was stright and really pounded me. I changed it to a cheap Ramline and that really tamed it. I worked up a good hot load for hunting here in Alaska using a 225gr bullet. I can reach out and touch things out to 500 yards real nice. My wife gave me a New Stainless Steel Ruger .338 last year for Fathers day. I finally got a good scope and took it out to shoot. I figured the same loads for my other .338 would be fine, Boy was I wrong. First shot I really got pounded hard, I looked at the case and saw the bolt face imprinted on the case head. Metal had flowed into the extractor hole. I realised that I had a high pressure problem with this gun and those loads. I finally got a good load by dropping 2 full grains of powder. The velocity and range are not the same though. I'm sticking with my old blue .338 for all my Moose and Grizzly hunting.
