[QUOTE="Mikecr, post: 2345860, member: 1521"] The best lapping is not a polish. It provides a 'smooth' surface profile that just happens to be best. If you polish a bore, you've ruined it -until properly re-lapped (hopefully recoverable). I tested this with a good barrel once, using Flitz, just for the learning I guess. The cut rifled barrel immediately went from no copper with 50sht clean rate, to copper fouling out by the 2nd group. Then I tried to recover the bore with JB cleaning compound. No good. Tried Tubb's FF, even that did not work. Ruined [/QUOTE]
