This Kit will do many barrels depending on cartridge size.
Disk shaped polishing compounds of optical quality that smoothes the bore's surface by fire lapping it with little steel removal. This product can be used to polish your bore as smooth as glass.
Puff-Lon fire lapping ballistic filler is made with optical quality disk shaped polishing compounds, which makes it difficult to imbed into the surface you are trying to polish. The polish is impregnated into a lightweight 100% Pure Cellulose that is compressible and has resiliency. It is granulated so it can be handled with the same ease as your gunpowder and has an infinite shelf-life.
Lapping bores by firing cartridges that have abrasive fillers is a refined concept. Every gun will benefit from bore lapping in this manner. Cleaning will be easier and accuracy will be improved. The bore lapping process removes only a small amount of steel, therefore it will not remove deep pits but does smooth the edges of them.
The kit contains four grades of polishing compound:
Coarse: Use on new production barrels to smooth out machining marks or barrels with erosion or corrosion.
Medium: Use after coarse or on medium smooth barrels.
Fine: Use after medium or on smooth barrels.
Extra Fine: Use after fine or to achieve a mirror finish inside the bore and for periodic maintenance. Use Puff-Lon "Lubricating Ballistic Filler" to keep it that way.
