The Hornady Superformance series delivers up to 60 mps higher exit velocity than other ammunition. This is because of its powder mixture in the Superformance series. The Hornady SST (Super Shock Tip) is designed to deliver a powerful shock effect when hitting the target. At the same time as it expands quickly and controlled especially at higher speeds. The SST is a bullet with good aerodynamic properties and good impact on the target.
