Hornady Superformance 7mm-08 Rem 139gr CX Ammo, 20rd

Description

The Hornady Superformance 7mm-08 Remington with 139-grain CX bullets brings the speed where it matters. These rounds deliver muzzle velocities around 2910 fps and 2613 ft-lbs of energy, achieved through Hornady's proprietary progressive propellant technology. Unlike standard loads that rely on heavy powder charges, Superformance propellants are engineered to combust completely and efficiently within standard barrel lengths. The burn rate brings peak pressure up more gradually than traditional powders while holding it longer, allowing these rounds to accelerate faster without exceeding SAAMI pressure limits.

CX Bullet Design Built for Hunting

The CX bullet represents Hornady's advanced monolithic hunting design. Unlike traditional jacketed bullets, this solid copper-alloy construction won't separate on impact, maintaining over 95 percent weight retention for consistent penetration. The bullet features a proprietary Heat Shield polymer tip that resists aerodynamic heating and delivers a consistently high ballistic coefficient throughout the flight path. Grooves along the bullet's sides maximize aerodynamic performance while reducing bearing surface friction and fouling. This all translates to extended effective range, better accuracy, and devastating terminal performance on medium-sized game.

Superformance Performance Advantages

With these loads running 100 to 200 fps faster than conventional ammunition in this caliber, you get a noticeably flatter trajectory and reduced wind drift without the downside of increased recoil, muzzle blast, or temperature sensitivity that often comes with hot loads. The ammunition groups without increased felt recoil and maintains consistent performance across a broad temperature range. Each box contains 20 rounds of new production, non-corrosive ammunition loaded in reloadable brass cases with quality primers.

The 7mm-08 Platform

The 7mm-08 Remington strikes a balance between power and shootability. Derived from the 308 Winchester and necked down for 7mm bullets, this short-action cartridge delivers mild recoil while maintaining the ballistic advantages of 7mm projectiles. It performs well on deer and elk-sized game and holds its own to around 500 yards depending on bullet selection and shooter skill. The 139-grain Superformance load fits right in the sweet spot for this cartridge, offering the heavier bullet weight that pairs well with the CX's monolithic construction and controlled expansion characteristics.
