Hornady Superformance 7mm-08 Rem 139gr CX Polymer Tip Lead-Free Ammo - 20 Rounds

Hornady Superformance 7mm-08 ammunition pushes your rifle to its potential without the penalties of conventional loads. This 139-grain CX polymer tip, lead-free round is built for hunters and shooters who demand velocity and accuracy on medium to large game—delivering speeds 100 to 200 fps faster than standard ammunition while maintaining the shot placement and consistency that matter in the field.

The engineering behind Superformance hinges on progressive propellants that burn differently than traditional powders, unlocking extra performance without cranking up chamber pressure, felt recoil, muzzle blast, or temperature sensitivity. That means whether you're shooting in fall cool or summer heat, your rounds perform the same way downrange. The CX bullet—a lead-free option for hunters in sensitive areas—combines with Hornady's quality case and primer selection to deliver the kind of round-to-round consistency that builds confidence at the range and in the field.

This is ammunition built for the 7mm-08, a cartridge loved by hunters who refuse to compromise on accuracy or stopping power in a lighter-recoiling package. Whether you're taking medium game out to 200 yards or pushing into the heavier classes, Superformance gives you the velocity and reliability to make clean kills without reinventing your rifle's ergonomics or breaking the bank on recoil management.

Frequently Asked Questions

What is Hornady Superformance ammunition and how does it work?

Superformance uses proprietary progressive propellants that burn at different rates than conventional powders, delivering an extra 100–200 fps of velocity without increasing chamber pressure or recoil. That gain translates to flatter trajectories and harder-hitting rounds downrange—all from the same rifle you already own.

Is the 139gr CX bullet lead-free?

Yes. The CX (Copper eXpanding) bullet is a lead-free option, making it compliant with lead ammunition restrictions in some regions while delivering reliable expansion and performance on game.

What game is this load designed for?

Hornady designed this 7mm-08 Superformance round for both medium game (50–300 pounds) and large game (300–1500 pounds), making it versatile for deer, elk, and other game in that range.

Will Superformance ammo shoot the same in cold and hot weather?

Yes. Unlike some premium loads, Superformance ammunition is formulated to perform consistently across a broad temperature range, so your zero and impact point won't shift between seasons.
