Hornady Superformance 7mm Rem Mag 139 gr SST – 20rd Box

Description

Hornady Superformance rifle ammunition combines a 139-grain Super Shock Tip (SST) projectile with Hornady’s progressive Superformance propellant to deliver higher muzzle velocities than conventional loads while maintaining standard pressure and felt recoil characteristics. This 7mm Remington Magnum load is packaged 20 rounds per box and is built on brass cases with primers chosen for consistency. Superformance cartridges are described by the manufacturer as safe for use across a wide range of rifle actions, including semi-automatic, lever, and pump-action designs, and are commonly used for medium game hunting where a high-velocity, polymer-tipped bullet is desired.
