What I mean is mis-loading. I have 2 MK II's - a true oldie from 1983 or so and a newer one - Government model. Upgraded both with Volquartsen triggers etc. - both are bull barrels and frankly shoot about the same accuracy. My problem is that recently, the newer Gov't model doesn't seem to like standard velocity ammo, and frequently will not load a second or third round in a clip. Ejects the spent round properly, and closes the bolt on an empty chamber. Not sure if this is related to the magazine? or something else. My old MK II bull barrel never fails to load anything I put in the clip. Any help will be grandly appreciated.
