20rds – 7mm Mauser Hornady Superformance 139gr. GMX Ammo Details

This 7mm Mauser cartridge from Hornady’s Superformance line of ammunition features a 139 grain GMX projectile. It’s a lead-free bullet, and the copper alloy it is made of is even stronger than pure copper alone would be! As the result this is a bullet that not only shoots incredibly clean and fouls only very little, but further is able to lose no more than five percent of its mass as it tunnels through its target. This bullet’s polymer tip initiates expansion of up to 1.5 the GMX’s original diameter, and along with its cannelure and pressure relieving grooves does a great job of improving its accuracy. The GMX performs so well that even hunters who aren’t subject to ammunition laws like California’s ought to consider trying it out during their next hunt!

The GMX’s accuracy is even further boosted by this Superformance round’s progressive propellant. It increases a rifle’s muzzle velocity by as much as 200 fps, but without adding unwanted side effects including greater recoil, increased muzzle blast, and more fouling. This round’s brass casing is reloadable and its propellant and primer are both clean burning.
