Wheeler Lapping Compound 220 Grit Cutting 1 oz

A high quality silicon carbide abrasive paste that is used for lapping the bore of a firearm, the bolt face, bolt lugs and a hundred other uses where a perfect final fit or a lapped smooth surface is needed. When lapping a bore, pressure will likely increase with grit impregnated bullets. Due to the likely increase of pressure, light loads are recommended. Five shot strings up to a maximum of twenty shots of each grit are recommended. Repeating the process using progressively finer grits will produce a significantly smoother bore.
