  • Patent number: 4080899
    Abstract: Shot pellets for a shotgun cartridge are encapsulated with light reflective coatings. The reflective coatings permit nighttime tracking of the shot pellets'trajectory to the target situs. A thin, lubricant film prevents adhesion between coated pellets when they are tightly packed in the shot chamber of the cartridge. A protective, plastic liner surrounds the shot pellets in the shot chamber and moves with the pellets from the barrel of the shotgun to prevent frictional erosion of the shot pellets and fouling of the barrel.
