You bought a Lever Broomhandle too? Mine is like a Frosted Mini Wheat. Sweet on the outside, crusty on the inside. How many mixed numbers do you have?
I'll settle for a 7.65 rebore to preserve the original cartridge, but 9mm is 1000x more available than the little bottlenecked Mauser cartridge.
(Paul Rogan asked for feedback on barrel liner in the Jan Access to Firearms. Has anyone seen the responses?)
