Many older shotguns have barrels that are badly pitted and need to be polished before shooting them. This video teaches the process of honing shotgun barrels to remove pitting using a Sunnen brand hone. Larry Potterfield, CEO and Founder of MidwayUSA, starts the process by measuring the location of the choke tape using a bore gage. He then sets a stop collar on the Sunnen hone to prevent polishing that surface. Once the stop collar is set, the bore is oiled with a honing lubricant and the hone is inserted in the barrel. The hone is turned at a medium speed until enough material is removed that the polishing stones need to be tightened. This process is repeated using progressively finer stones until the desired finish is reached.
