20rds - 7mm Mauser Hornady 139gr. SST Superformance Ammo Details

Engineered specifically for deer hunting, Hornady Superformance ammunition produces speeds up to 200 feet per second faster than any conventional hunting load on the market. Producing effective and reliable on-game performance and impressive long-range accuracy, Superformance raises the bar for sporting ammunition performance.

This 7mm Mauser (7x57mm) ammunition features progressive propellants that send the 139 grain SST (Super Shock Tip) projectile to a performance level previously unattainable. And Hornady achieves this without increasing felt recoil, muzzle blast, temperature sensitivity, or barrel fouling. Each round achieves a muzzle velocity of 2760 feet per second and produces 2351 foot pounds of muzzle energy.

SST projectiles are designed to produce a disastrous lethal shock wave upon target impact while delivering rapid and reliable expansion. These proprietary bullets are especially effective at producing terminal results at the higher velocities produced by Superformance progressive powders.

The SST design also features Hornady’s exclusive InterLock ring which mechanically locks the copper jacket to the lead alloy core during expansion. The result is increased weight retention, explosive energy transfer, and deep soft tissue penetration.

This factory fresh ammunition is 100 percent non-corrosive, boxer primed, reloadable, and brass cased. Each package contains 20 rounds of Hornady Superformance 7mm Mauser ammunition.
