Hornady

Superformance 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. The Superformance solution is an elegant approach that utilizes specialized powders at normal charge weights, that impart all usable energy to the bullet reducing the rocket nozzle effect at the muzzle while still increasing velocity.
