Oldude Posted December 23, 2005 Report Share Posted December 23, 2005 Hi I'm new to this board but was a member of the old board (BC) before the crash. I've just been watching and learning and collecting mausers and parts. Its time to start building something. My question is, How much do you have to open the bolt face for the magnum ? i'm thinking .030 but wanted to be sure. Thanks Oldude Link to comment Share on other sites More sharing options...

ken98k Posted December 23, 2005 Report Share Posted December 23, 2005 Jerry Kuhnhausen's book on mauser actions give detailed instructions for opening bolt faces on page 169. Kenny Link to comment Share on other sites More sharing options...
Guest z1r in Texas Posted December 24, 2005 Report Share Posted December 24, 2005 Cut a radius of .269". The boltface needs to be .532" plus about .006" for clearance. Link to comment Share on other sites More sharing options...

Clark Posted December 26, 2005 Report Share Posted December 26, 2005 I can't fit the bolt body in the 4 jaw unless I hack saw off the bolt handle. Then bolt forging is out and welding is a must. Also I Dremel tool faked the flare at the bottom of the face. Next time I want to mill it or grind it on the lathe so it is a little nicer than a Tokarev safety [made by slaves with grinders].
