Hornady 80593 Superformance 7mm Rem Mag 139gr SST Ammo 20rd Box

The Hornady 80593 Superformance ammunition delivers exceptional velocity and accuracy for 7mm Remington Magnum rifles. This premium hunting load combines Hornady's proprietary Superformance propellant technology with the proven Super Shock Tip (SST) bullet design to maximize downrange performance. Hunters gain significant advantages in trajectory and energy retention compared to standard magnum loads.

What Makes This Different

Superformance technology increases muzzle velocity by 100-200 fps over conventional ammunition without increasing chamber pressure or barrel wear. The 139-grain SST bullet features a polymer tip that initiates rapid expansion upon impact while the InterLock ring prevents jacket separation. This combination delivers consistent terminal performance across a wide range of hunting distances, making it superior to standard cup-and-core bullets that may fail to expand reliably.

Key Features

• 139-grain Super Shock Tip (SST) bullet with polymer tip for rapid expansion
• Superformance propellant increases velocity 100-200 fps over standard loads
• InterLock ring mechanically locks jacket to core preventing separation
• Boat tail design reduces drag for flatter trajectory and retained energy
• Premium brass cases engineered for consistent powder capacity
• Match-grade primers ensure reliable ignition in all conditions
• 20 rounds per box, 10 boxes per case (200 total rounds)

Field testing demonstrates this load's effectiveness on medium to large game at extended ranges. The 139-grain bullet weight provides an optimal balance of velocity and sectional density for the 7mm Remington Magnum cartridge. Hunters report excellent accuracy from factory rifles, typically achieving sub-MOA groups when paired with quality optics. The SST bullet performs consistently on whitetail, mule deer, elk, and similar-sized game from 50 to 400+ yards.
