I once built a 300 wm on a post war fn 30/06 military action. I actually broke down a military rifle to get the action. this was one of the slickest actioned rifles I have ever owned. I have been told that the metal in these actions is as good as it gets, and it was not made under duress of war. If I were building a mauser now I would actively seek out one of those actions again. the only action work for feeding was to open the rails slightly at the front to clear the belt on closing the bolt. I kept the military floorplate, and would do so again, particularly on a dangerous game rifle. the only semi finished stock I could buy was birdseye maple, and it came up a treat. bruce.
