Hornady Superformance 7mm Remington Magnum ammunition with 139 grain SST bullets delivers velocity gains up to 200 fps beyond conventional loads without adding pressure, recoil, or thermal sensitivity. The SST (Super Shock Tip) projectile combines a streamlined polymer tip with Hornady's InterLock ring technology, engineered for rapid expansion and deep penetration on medium to large game at extended ranges.
This 7mm Remington Magnum load achieves 3,240 feet per second from standard rifle barrels, a ballistic performance level that Hornady's progressive propellant chemistry makes possible without the traditional trade-offs of temperature sensitivity or chamber fouling. The 139-grain bullet weight sits at the efficiency sweet spot for the 7mm Rem Mag, balancing sectional density with velocity retention over distance. Each box contains 20 rounds, allowing serious hunters and long-range marksmen to maintain consistent point-of-impact and energy downrange.
Superformance ammunition is specified for hunters pursuing elk, mule deer, and other large game where extended-range capability and flat trajectory are operational requirements. The SST bullet design and velocity envelope make this loading particularly suited to cold-weather hunts and high-altitude applications where temperature variance and thin air demand ballistic consistency. Reloaders and ammunition developers frequently reference Hornady Superformance loads as baseline data for working up precision handloads in the 7mm Remington Magnum.
