Forgot to address your question. It seems to have been factory original, unfired when I got it. Alpha Arms, as I recall, listed .338-284 as an option in their catalog, which I have. Just have to check it again to make sure. Previous owner must have snapped it a lot as the firing pin was broken and I had to get James Flynn, gunsmith to fabricate a new one from scratch. James builds parts for and restores Purdys, Hollands, etc. Check him out on line with a word search. You'll be amazed at what he can do. His shop in here in Alexandria, LA and I knew him growing up. His heat treated firing pin was far superior to the factory original. That was my only option as I didn't want to return the gun as defective, liked it enough to spend some extra on it. Wasn't cheap, but a LOT less than James gets for his "high dollar" work. He gave me a BIG break on that one. Guess he felt sorry for me.
