What Makes Hornady Superformance 7mm Remington Magnum 139 Stand Out?
The Hornady Superformance 7mm Remington Magnum 139 is designed to deliver exceptional velocity and flat trajectories. This ammunition aims for a higher performance ceiling than standard 7mm Rem Mag loads. Hornady’s Superformance line is built around progressive powders, promising consistent results and greater energy on target.
My quest for flatter shooting and increased downrange energy for my aging 7mm Rem Mag rifle led me to the Hornady Superformance 7mm Remington Magnum 139. I was seeking ammunition that could extend my effective range on elk in the rugged backcountry of Montana. The allure of improved ballistics and the reputation of Hornady drew me in.
The ammunition came packaged in a standard cardboard box, neatly arranged. The cartridges themselves looked clean and well-made, with the Super Shock Tip (SST) bullets gleaming. The overall presentation exuded quality and attention to detail.
Compared to Federal Premium 140 grain and Winchester Ballistic Silvertip 150 grain, the Hornady Superformance 7mm Remington Magnum 139 promised the highest velocity. This was the deciding factor, as a flatter trajectory would be vital for the longer shots I anticipated. I hoped to see significant improvements in range and terminal performance.
I was definitely excited to try out the Hornady Superformance 7mm Remington Magnum 139. The claimed velocity gains had me eager to see how it performed in my rifle. I had high expectations for its accuracy and overall effectiveness.
Real-World Testing: Putting Hornady Superformance 7mm Remington Magnum 139 to the Test
First Use Experience
I tested the Hornady Superformance 7mm Remington Magnum 139 at my local shooting range, under clear, sunny conditions. The range offered distances out to 500 yards, perfect for evaluating the bullet’s trajectory. I used a Caldwell Lead Sled to minimize shooter error.
The ammunition performed well in the mild conditions, exhibiting consistent velocities and manageable recoil. The rifle cycled smoothly, and the spent cases ejected cleanly. There were no immediate indications of over-pressure.
The recoil was noticeable but not punishing, about what I expected from a magnum cartridge. It was manageable enough for accurate follow-up shots. The ease of use was excellent; I simply loaded the magazine and started shooting.
The only minor issue I noticed was a slightly louder report compared to my standard hunting load. This wasn’t a significant problem, but it was noticeable. Overall, the first range session was positive.
Extended Use & Reliability
After several months of use, the Hornady Superformance 7mm Remington Magnum 139 has proven to be reliable. I used it extensively during the hunting season, encountering various weather conditions. The ammunition performed flawlessly in both dry and moderately wet environments.
I’ve fired approximately 100 rounds of this ammunition, and I have yet to experience a single misfire or failure to feed. There are no visible signs of wear and tear on the cartridges themselves. The brass has held up well to reloading.
Cleaning and maintaining the rifle after using this ammunition is no different from any other centerfire cartridge. Standard bore cleaning solvents are effective. The brass cleans up nicely with tumbling.
Compared to my previous experiences with other 7mm Rem Mag loads, the Hornady Superformance 7mm Remington Magnum 139 offers a flatter trajectory and noticeably more energy at longer ranges. It has definitely outperformed my expectations. It has instilled greater confidence in my long-range capabilities.
