Shotgun manufacturers are building
firearms that are lighter and easier-to-handle. To satisfy shooters who want
lighter-weight weapons, companies like Browning are using steels that can
contain thousands of pounds of pressure per square inch (psi). “If shortening
the barrel is not an option”, Reid Coffield from Shooting Times
explains, factory
gunsmiths “make the barrel walls
thinner.” Unfortunately, these thin-walled shotgun barrels are
susceptible to dents ranging from cosmetic flaws to safety hazards.The Flex-Hone® for Firearms
Severe dents are visible not just on the outside of a shotgun barrel, but on the inside of the bore, too. “There have been a number of ways of removing dents,” Reid Coffield explains, noting his preference for a hydraulic dent-raiser that’s made in England. For a final polish after the dents are removed, however, Coffield recommends a brush tool that’s made in the U.S.A. – the Flex-Hone® for firearms from Brush Research Manufacturing (BRM).
Shotgun Barrel Hones
BRM offers a full line of Flex-Hone® tools for firearms, but the abrasive brush Coffield writes about in “The Ins and Outs of Shotgun Barrel Dents” is the shotgun barrel hone for smoothbores. Built with a stiff, coated stem and finger-like formations of abrasive globules, the Flex-Hone® follows the geometry of the bore to polish the metal gently and create a uniform surface finish. The Flex-Hone® is designing for polishing and is not, as the Shooting Times article indicates, capable of removing dents.
Polishing Shotgun Barrels
The Flex-Hone® shotgun barrel hone polishes a smooth bore to a beautiful finish and creates a surface that reduces fouling and resists corrosion and wear. Available in 10, 12, 16, 20, and .410 gauges (GA), this abrasive brush tool uses medium or fine grits of either aluminum oxide (AO) or silicon carbide (SC). For best results, BRM advises gunsmiths to use with Flex-Hone® oil, a proprietary blend of honing and lapping oils that assures complete surface lubrication.
