Ammo Overview

Quantity - 20 rounds
Manufacturer - Hornady
Bullets - 139 grain Super Shock Tip (SST)
Casings - Boxer-primed Brass


This 7mm Rem Mag cartridge from Hornady’s Superformance line of ammunition features a 139 grain Super Shock Tip (SST) projectile. The SST bullet sports a polymer tip that drives into its core like a wedge upon impact to initiate fast and controlled expansion, as well as to improve its accuracy by streamlining its shape. This bullet further incorporates a mid-body cannelure as well as Hornady’s InterLock ring, which together lock its core and jacket in place for optimal weight retention and deep penetration. Finally, the tapered base of this bullet improves its accuracy, increases its ballistic coefficient, and grants it some resistance against the harmful effects of cross winds.

This round’s 3,240 fps muzzle velocity is about 100 to 200 fps faster than other comparable cartridges, so you’ll notice a exceptionally flat trajectory while firing it. The cartridge further offers a progressive and clean burning powder, high quality reloadable brass casing, and uniform and reliable primer.
