Ar15 gasblock temperature2/5/2023 Once the peak pressure dissipates, the Superformance powder burn returns to a “normal” curve, similar to standard propellants. In other words, both Superformance and standard propellants provide an equally powerful “push” applied to the base of the bullet, but with Superformance propellants, the “push” is applied for a longer period of time. Superformance propellants provide a longer duration/application of peak pressure in the pressure time curve that occurs within the barrel (see Fig. All Superformance loads exhibit extremely stable performance with very little if any deviation in pressure and velocity at extreme temperatures. Superformance ammunition was developed in the Hornady ballistics lab utilizing state of the art test equipment in accordance with SAAMI (Sporting Arms and Ammunition Manufacturers Institute) guidelines for pressure, velocity and accuracy utilizing test barrels with SAAMI minimum specification chambers and bore and groove dimensions.Īll ammunition is extensively tested for pressure and velocity deviation at temperatures from - 20☏ to + 140☏.
