Superformance ammunition is loaded with proprietary propellants that increase the velocity ratings up to 200 feet per second compared to other popular brands. Because there is no increase in pressure, regardless of the calibre, there is no increase in felt recoil but there is an increase in efficiency and high speed performance. From sub-zero arctic temperatures to almost unbearable desert heat, Superformance ammunition can withstand any hunting habitat. 

The Spire Point - Recoil Proof bullet is simply Hornady's InterLock Spire Point bullet with the unique ring that ensure the core and jacket remain locked together during expansion. The InterLock retains more mass, energy and momentum after impact and transfers that energy to the target. The exposed lead tip is flush with the jacket. The fact that it's Recoil Proof helps large calibres and also assists with premature mushrooming.
