If you're going to brand something "superformance," the product better possess superior performance across all platforms of competitive measurement, and Superformance Ammunition from Hornady does just that.
Using a revolutionary propellant, the ammunition line is 100 to 200 fps faster than any conventional ammunition on the market today and "achieves this feat in any gun without increases in felt recoil, muzzle blast, temperature sensitivity, fouling or loss of accuracy." The load uses a SST or GMX bullet and powders at normal charge weights. A wide variety of your favorite calibers are available. (price listed is MSRP for 95-grain SSTs).
