Have about 50 .348 cases formed and trimmed to .44-77, but the rims are .076-.077 and they will supposedly fit the Shiloh chambers, but not the C. Sharps chambers, which take a thinner .067 rim. This must have been the reamer my gunsmith used. So I need to find a "cartridge machinist" who can uniformly shave .01 off the forward edges of the rims on these cases. Anyone out there wants to raise their hand or direct me to a good source for this work?
