Hornady

Superformance ammunition is 100 to 200 fps faster than conventional ammunition, and achieves this performance in every gun, without increases in felt recoil, muzzle blast, temperature sensitivity, fouling, or loss of accuracy. The Superformance solution 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.
