Superformance uses ultra progressive propellants that take your favorite SST bullets to levels of performance that are simply unattainable with conventional propellants. In order to get more velocity in the past – shooters have used a brute force approach – large charge weights of a slow burning powder in a larger cartridge case. Ultimately this leads to more recoil and muzzle blast. The Superformance solution is an elegant approach that utilizes specialized powders at NORMAL charge weights, that impart ALL useable energy to the bullet reducing the ROCKET NOZZLE EFFECT at the muzzle while still increasing velocity!\r\nFeatures\r\n\r\nSuperformance ammunition is 100 to 200 fps FASTER than any conventional ammunition on the market today, and achieves this performance in EVERY gun, WITHOUT increases in felt recoil, muzzle blast, temperature sensitivity, fouling or loss of accuracy.\r\nSuperformance uses ultra progressive propellants that take your favorite SST bullets to levels of performance that are simply unattainable with conventional propellants.
