[QUOTE="shortgrass, post: 2345801, member: 24284"] The lead laps I've been around have the abrasive mixed into the molten lead and are poured right in the barrel that is to be lapped. A plug is inserted in the bore before the molten lead is poured, so it doesn't just run down the barrel, but forms a slug that is the lap. It fits the bore perfectly. The 'slug' is cast with a rod into it, so it can be pushed and pulled. It wears quickly. Wrapping a patch around a brush and applying a polishing compound may not 'lap' the entire bore. Besides, it's polishing compound and not abrasive enough to actually "lap", remove the high spots/tool marks. [/QUOTE]
