At Challenger ammunition, state-of-the-art ballistic testing equipment - including a universal receiver, sensitive quartz pressure transducers and advanced chronographs - is employed to precisely measure shotgun shell pressures and velocities. Comprehensive quality checks are performed on all other factors to ensure consistent reliability. Their primers benefit from modern innovations, guaranteeing steady performance with every shot. Slow-burning powders reduce recoil and shot deformation for outstanding results. The one-piece plastic wad, available in both double and single piston variants, improves performance for both clay shooters and hunters. The tubular reducer boosts shot impact without compromising penetration, while the extra-hard lead shot with high-antimony content delivers denser patterns and maximum penetration. Reloadable plastic hulls provide economical advantages, all produced in Challenger's high-tech, quality controlled facilities.
