I have a winchester rifle at home in 300WSM. It is the lh pre-64 type action with the claw extractor. It is not a shooter. I have shot many type loads with mixed results. So, thought i would make a custom build in 300WSM. A tactical/hunter. Has anyone built a custom or seen one built on the winchester action. Is it fesible? I love this action, I have just never got it to shoot. So, a build may be in my future.
