Hornady Superformance 7mm Rem Mag 139gr SST – 20 Rounds

Hornady Superformance 7mm Remington Magnum delivers 100–200 fps more velocity than conventional loads without increased chamber pressure or recoil. The 139-grain SST (Super Shock Tip) bullet features a polymer tip that initiates rapid expansion on impact and a secant ogive profile for superior ballistic coefficients. The InterLock ring mechanically locks the core and jacket together during expansion, ensuring deep penetration and high weight retention on medium to large game including deer, elk, and black bear.

This ammunition is loaded with proprietary propellants optimized for magnum bolt-action rifles. Hornady uses their own brass cases and select primers for consistent ignition and velocity across temperature extremes. Superformance loads are safe in all 7mm Rem Mag firearms including semi-autos, pumps, levers, and bolt actions. Available in 20-round boxes.
