A one-piece shot cup (also commonly known as a shot pouch) designed especially for use in protecting the bore of a shotgun barrel when shooting hard shot made of a material such as tungsten or non-annealed steel. The cup is characterized by the use of shield members located opposite and outwardly of equally spaced tear lines which are defined by narrow areas of substantially weakened wall structure extending longitudinally of the cup. The shield members are connected to the wall structure of the tubular members only adjacent its closed rear end portion and are otherwise separate and free thereof. Portions of the tubular members extend between the circumferentially spaced shield members. The shield members prevent the shot, which ruptures the tear lines, from damaging the bore of the shotgun barrel. They also aid in holding the shot in an improved aligned relation to thereby improve the shot pattern. They also aid in causing the shot cup to separate from the shot immediately after leaving the end of the barrel of the gun. The tapered wall thickness of the pouch is within the range of 0.060" at its front end and 0.080" at the rear end of the pouch.
