Increase your rifle's performance up to 200 fps without extra chamber pressure, recoil, muzzle blast, temperature sensitivity, fouling, or loss of accuracy. Superformance uses progressive propellants that take your favorite bullets to levels of performance that are simply unattainable with conventional ammunition.

With its increased speed, Superformance produces flatter trajectories and less wind drift for improved accuracy as well as better energy transfer for maximum terminal performance. Highly efficient propellants accelerate the bullet longer, resulting in up to 200 fps increase in muzzle velocity, without additional peak pressure, boosting velocity without extra recoil. The ultimate all-around performer, Superformance is safe in all types of firearms including semi-autos, lever guns, and pump actions.
