This combination of lapping grits allows for cutting (220), smoothing (320), and polishing (600) your firearm's bore. The compound is useful for a variety of applications including lapping bores, bolt faces, and bolt lugs. 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. Use progressively finer grits to reach a significantly smoother bore. Each 1 oz jar includes high-quality silicon carbide abrasive paste.
