I haven't had any response from Clearwater Reboring about my proposed job,and until I can find another shop, I thought I'd like to hear from any of you regarding what I need done. I have an excellent JP Sauer 9x57, but the throat is quite eroded. Accuracy seems to be about 3" gruops for five shots at 100 yds with jacketed bullets. Lead seems to shoot about the same for 3 or 4 shots and then spreads badly. Can this .356 bore be opened to .366? If the change has to be big enough to ream the existing rifling completely out, then I'd have to go to a .375.I want to save this barrel if at all possible. Any recommendations or suggestions?
