Tungsten-alloy pellets, regardless of size, require a shotcup specifically designed to manage the weight (i.e., density) and hardness of the pellets. Tungsten Propulsion System (TPS) shotcups by BPI are made to handle the physical rigors of tungsten-based pellets, like Hevi-Shot and ITX EX-13, minimizing the risks of pellet contact and protecting your barrel and chokes.
Our custom TPS molding resin is soft and pliable; TPS wads provide an unmatched barrier between pellet and barrel. New material technology allows the TPS design to absorb and harness the energetic nature of hard tungsten alloys and steel shot.
