First Use Experience
My primary testing ground for this ammunition has historically been the wide-open spaces of western Nebraska during deer and antelope seasons, as well as various private ranges for load development and accuracy checks. The 7mm Remington Magnum, especially when paired with the velocities achieved by Hornady’s Superformance propellants, truly shines at extended ranges, often exceeding 500 yards under favorable conditions. During these field tests, I’ve subjected these rounds to the usual rigors: varying temperatures, occasional dust storms, and the general bumps and jostles of carrying a rifle through rugged terrain.
The ease of use with this ammunition is, as expected, non-existent in the sense that it’s simply ammunition. However, its consistent chambering and ejection in my trusted rifle have been flawless, requiring no special handling beyond standard firearm safety protocols. A minor surprise during one particularly brisk morning was the slightly firmer resistance when chambering a round compared to some standard loads, which I attribute to the precise fit and perhaps a slightly cooler ambient temperature affecting the brass.
Extended Use & Reliability
Over years of use, this ammunition has proven itself to be exceptionally reliable. It’s become my go-to for medium to large game where ethical one-shot take-downs are the goal. The durability of the cartridges themselves is evident; I’ve had boxes stored for several years with no discernible degradation in performance. The brass cases show consistent primer seating and no signs of corrosion, even after prolonged periods in less-than-ideal storage conditions in my workshop.
Compared to other factory loads I’ve experimented with over the years, the Hornady Superformance 7mm Remington Magnum 139 Grain Super Shock Tip Centerfire Rifle Ammunition
80593 13% Off consistently offers a noticeable advantage in both velocity and retained energy downrange.

Specifications
The core of this ammunition’s performance lies in its carefully matched components. The Hornady Superformance 7mm Remington Magnum 139 Grain Super Shock Tip Centerfire Rifle Ammunition
80593 13% Off features a 139-grain Super Shock Tip (SST) bullet. This projectile is designed with a boat-tail base for improved ballistic coefficient and a polymer tip that initiates rapid expansion upon impact. The bullet’s construction, a copper-jacketed lead core, is optimized for controlled expansion and deep penetration on game.
The cartridge case material is standard brass, known for its durability and reliable extraction properties. Hornady utilizes progressive propellants specifically formulated for their Superformance line, which deliver significantly higher velocities compared to conventional ammunition. This results in a muzzle velocity of 3,240 feet per second and a corresponding muzzle energy of 3,239 ft-lbs. These higher velocities contribute to a flatter trajectory, meaning less holdover at longer distances, and increased kinetic energy delivered to the target. The G1 ballistic coefficient of 0.486 and sectional density of 0.246 further highlight the bullet’s aerodynamic efficiency. Each package type is a box containing 20 rounds, which is a standard and convenient quantity for range use and hunting trips.
Performance & Functionality
The primary job of this ammunition is to deliver accurate and effective terminal performance on medium to large game, and it excels at this task. The 139-grain SST bullet consistently achieves impressive accuracy, typically grouping within 1 MOA or better from my rifle at 100 yards. What truly stands out is its performance upon impact; the polymer tip reliably peels back the jacket, initiating a controlled and devastating expansion that results in significant wound channels and rapid incapacitation of game animals.
A significant strength is the combination of speed and bullet design, which translates to exceptional performance even at longer ranges. The increased velocity means less bullet drop and less time of flight, making target acquisition at distance more straightforward. While I haven’t encountered any significant weaknesses, it’s important to note that the high velocity generated by Superformance powders might accelerate barrel wear slightly faster than standard loads over extremely high round counts, though this is a minor consideration for most hunters and sport shooters. It consistently meets, and often exceeds, the performance expectations for premium hunting ammunition in this caliber.
Design & Ergonomics
The design of the Super Shock Tip bullet itself is a marvel of modern ballistic engineering. The polymer tip isn’t merely cosmetic; it’s integral to the bullet’s aerodynamic shape and its terminal ballistics. The boat-tail design further enhances stability in flight, contributing to its excellent accuracy. The copper jacket is precisely formed to work in concert with the lead core, ensuring that the bullet performs as intended upon striking a target.
The overall feel of the cartridge is one of quality and precision. The brass cases are well-formed, with consistent wall thickness and primer pocket depth. The seating of the bullet is uniform, which is critical for consistent ignition and bullet launch. There’s no discernable “learning curve” with ammunition, but the understanding of its capabilities – the flatter trajectory, the energy retention – is what enhances usability. This ammunition simplifies the shooter’s task by providing a predictable and potent trajectory.
Durability & Maintenance
Ammunition, by its nature, is largely a consumable, but the durability of the components is crucial for long-term reliability. The brass cases used by Hornady are known for their reusability if one chooses to reload, and even for single use, they hold up remarkably well to the stresses of firing and extraction. I have had boxes of this ammunition stored in my climate-controlled workshop for several years without any issues.
Maintenance for ammunition primarily involves proper storage. Keeping it dry and away from extreme temperature fluctuations will ensure its longevity. There are no specific maintenance procedures beyond proper handling and storage. Potential failure points in ammunition are rare with reputable manufacturers like Hornady; however, if a primer is duded or a case shows visible damage (though I’ve never encountered this with this specific product), it should be safely disposed of. The robust construction suggests a long shelf life, making it a reliable choice for stockpiling.
Accessories and Customization Options
This particular product is ammunition, so the concept of “accessories” is limited. However, the ammunition itself is loaded with Hornady’s proven Super Shock Tip (SST) bullets, which are also available as components for handloaders. These bullets can be paired with other high-quality components, such as reloadable brass cases and primers, to create custom loads.
The Superformance propellants are proprietary blends that are difficult to replicate precisely for handloaders, making it challenging to perfectly match the factory velocities and performance without extensive testing. While the SST bullet itself can be purchased separately, replicating the exact Superformance load requires expertise and specialized powders. This makes the factory loaded Hornady Superformance 7mm Remington Magnum 139 Grain Super Shock Tip Centerfire Rifle Ammunition
80593 13% Off a convenient and often superior option for those seeking its unique ballistic advantages out of the box.
