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. Superformance uses ultra progressive propellants that take your favorite SST or GMX bullets to levels of performance simply unattainable with conventional propellants. In order to get more velocity in the past, shooters have used a brute force approach with large charge weights of a slow burning powder in a larger cartridge case which ultimately leads to more recoil and muzzle blast. 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. Superformance is safe to use in all firearms, including semi-autos, lever gun and pump actions. Increases in rifle performance, no increases in barrel wear and felt recoil, along with superior temperature stability are all realized with Superformance ammunition.

I use the Hornady Superformance ammo in several rifles, including my 338 RCM, 35 Whelen, and 7MM-08. The SST bullets in Hornady Superformance factory loads are deadly on whitetails. One caution to new users; the Superformance ammo tends to have a significantly higher point of impact than other factory loads and my own reloads. So check sight-in if changing ammo always. Recoil also seems higher.
