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 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.

The mono-metal Hornady GMX delivers a devastating terminal performance across a wide range of velocities. It's streamlined design offers ultra-flat trajectories while the gilding metal construction and double cannelures reduce fouling.
