The Williams was designed to clear the firearm's bore of black powder fouling, a major problem which affected accuracy and ease of loading of muzzle loaders. In the Williams design, a zinc washer was incorporated, which scraped the bore clean. The intention, for a rifle or carbine, was that a bullet of this design be used every 20 shots or so. It apparantly worked well, and Williams-design bullets were used exclusively in the Union machine gun. The Williams gained an undeserved reputation for damaging the bore among Union troops during the American Civil War, however, so its issue was discontinued.
