The Underwood Ammo .357 Magnum 158 Grain XTP Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition
124 45% Off immediately screams quality and power. Knowing Underwood Ammo’s reputation for pushing the limits of performance with meticulously crafted loads, I was eager to get my hands on this specific round. The combination of a time-tested projectile like the Hornady XTP, coupled with a potent .357 Magnum loading, promised serious performance.

My search for a high-performance .357 Magnum round for both hunting and personal defense led me to this particular ammunition. I needed a cartridge that would deliver both exceptional accuracy and devastating terminal ballistics. I hoped it would consistently provide reliable expansion and penetration across various distances.

Upon opening the box, the nickel-plated brass casings gleamed, suggesting attention to detail and corrosion resistance.

Compared to other popular .357 Magnum loads like the Federal Hydra-Shok or the Speer Gold Dot, I chose the Underwood Ammo due to its reputation for higher velocities and corresponding energy. The Buffalo Bore and Grizzly Cartridge offerings were also considered but Underwood struck me as having the best balance of velocity and manageable recoil. The 45% Off sale didn’t hurt either!

124 45% Off** to the Test

First Use Experience

I first tested the Underwood Ammo .357 Magnum 158 Grain XTP Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition
124 45% Off at an outdoor shooting range in controlled conditions. The weather was mild, approximately 65 degrees Fahrenheit, with a light breeze. I fired the ammunition from both a Ruger GP100 revolver (6-inch barrel) and a Marlin 1894 lever-action rifle (18.5-inch barrel) to assess its performance in different platforms.

The ammunition performed flawlessly under these conditions. There were no malfunctions, misfires, or signs of overpressure. The recoil from the Ruger GP100 was stout but manageable, while the longer barrel of the Marlin significantly reduced the felt recoil.

The Ruger required minor familiarization to manage recoil; the Marlin was controllable with minimal adjustment. The most noticeable aspect of the initial use was the loud report and significant muzzle flash, characteristic of high-velocity .357 Magnum loads.

There were no immediate issues, though the muzzle flash was certainly noticeable in the revolver. The consistent recoil and report gave a sense of confidence, which is vital in a defensive or hunting scenario.

Extended Use & Reliability

After several months of regular use, the Underwood Ammo continues to perform admirably. I’ve put approximately 500 rounds through both firearms with zero failures. This included a few outings in less-than-ideal conditions, including a light rain and a dusty environment.

The nickel-plated brass casings have held up well, showing no signs of corrosion or tarnishing, even after being stored in a range bag for extended periods. Cleaning the firearms after shooting Underwood Ammo is straightforward, with minimal powder residue left behind. I typically clean after every range session with a high-quality solvent and bore brush.

This ammo has outperformed standard factory .357 Magnum loads in terms of both velocity and accuracy. The consistency and reliability have been exceptional. The experience has bolstered my confidence in Underwood Ammo as a viable choice for both hunting and personal defense.
