I had some time today, and since I'm not thrilled with the accuracy of my sleeved ppsh barrel in my conversion, I turned down a new barrel. Since I have 3 extra 1919 barrels that I'll never be able to sell I figured I could use one as a donor and if I screwed it up, who cares. I'll turn down the other two barrels later and by the time I finish the third, if the chrome bores of the 1919 barrels have wiped out my .30 mauser chamber reamer, I'm not too concerned, I planned to sell the other two barrels anyway and I should break even on this project. The exact locations of the stepped down parts of the barrel are a little off from the romy barrel to match my gun which is already built. I may find a cheap reamer to removed the chrome before I run the chamber reamer in. Anyhow what do you guys think?
