Superformance GMX

7MM Remington, 139 Grain, 3190 fps, Gilding Metal Expanding (GMX)

The new Hornady GMX (Gilding Metal eXpanding) bullets and factory ammunition offer the hunter who favors an expanding monolithic bullet a better choice. GMX bullets are constructed of the same gilding metal used to make ultra-consistent Hornady bullet jackets. Gilding metal doesn’t foul like “sticky” solid copper, and strategically located grooves in the bearing surface of the bullet reduce pressure. Superformance ammunition is 100 to 200 fps faster than any conventional ammunition on the market today, and achieves this performance in every gun, without increases in felt recoil, muzzle blast, temperature sensitivity, fouling or loss of accuracy. Superformance 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 your favorite SST or GMX bullets 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 with 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 usable energy to the bullet reducing the rocket nozzle effect at the muzzle while still increasing velocity! Superformance provides increased performance, and is safe to use in all firearms, including semi-autos, lever gun and pump actions. Increases in rifle performance, no increases in barrel wear and felt recoil, along with superior temperature stability are all realized with Superformance ammunition. It really is Rocket Science.
