Hello All: Just started reading up on paper patching and found this site to be great. I do have a question though. I'm paper patching 45-70 bullets produced by a T.Ballard mold. After the bullet is patched and dried, it seems most recommend it to be lubricated. On checking some original bullets, the paper doesn't seem to be discolored by any sort of lubricant. In days gone by, was lubrication not used, or was it applied so as to be not visible above the case? Suggestions as to best lube? Thanks, Dan
