Hornady 5.56mm NATO Superformance Ammuniton is a cutting edge technological advancement in ammunition design that transcends convention and achieves the highest performance of any ammunition on the market today.

Superformance uses ultra progressive propellants that take the GMX bullet to levels of performance that are simply unattainable with conventional propellants. In order to get more velocity in the past – shooters have used a brute force approach – large charge weights of a slow burning powder in a larger cartridge case. Ultimately this leads to more recoil and muzzle blast. The Superformance solution is an elegant approach that utilizes specialized powders…at NORMAL charge weights, that impart ALL useable energy to the bullet reducing the ROCKET NOZZLE EFFECT at the muzzle while still increasing velocity!
