promises high velocity and deep penetration, making it an interesting option for hunting and potentially self-defense. Manufactured by Underwood Ammo, this round utilizes a solid monolithic bullet, nickel-plated brass casing, and is designed to be lead-free. Its reported muzzle velocity of 1700 ft/s and muzzle energy of 770 ft-lbs are certainly impressive figures.

I needed a reliable, hard-hitting round for handgun hunting medium-sized game, specifically deer and hogs. While I’ve used heavier .357 Magnum loads in the past, I was intrigued by the potential of a lighter, faster bullet with deeper penetration promised by the monolithic design.

Upon receiving the ammunition, the first thing I noticed was the pristine nickel-plated brass casings. They looked incredibly clean and well-made, instilling confidence in the quality control. The monolithic bullets themselves appeared solid and precisely manufactured, inspiring confidence.

I considered using Buffalo Bore’s .357 Magnum offerings and some heavier grain options from Federal, but the lead-free aspect of the Underwood Ammo and the promise of deep penetration swayed my decision. I was excited to see if this round could deliver on its claims of high velocity and controlled expansion/penetration.

My initial excitement was tempered by a bit of skepticism. Could a 120-grain bullet, even a monolithic one, truly deliver the necessary stopping power for ethical hunting at reasonable distances? Only testing would tell.

First Use Experience

My first test of the Underwood Ammo .357 Magnum 120 Grain Solid Monolithic Nickel Plated Brass Cased Pistol Ammunition
913 29% Off
was at my local shooting range. I used a Ruger GP100 with a 6-inch barrel as my test platform, aiming for paper targets at 25 and 50 yards. The weather was clear and sunny, around 70 degrees Fahrenheit.

The recoil was surprisingly manageable for a .357 Magnum round, likely due to the lighter bullet weight. However, the muzzle flash and report were definitely noticeable, indicative of the high velocity. Accuracy at 25 yards was excellent, with tight groupings well within the vital zone.

There were no malfunctions or issues with feeding and ejection. However, the point of impact was noticeably lower than my standard 158-grain loads, requiring some sight adjustment.

Extended Use & Reliability

After several months and approximately 200 rounds fired, the Underwood Ammo has proven to be remarkably consistent. I’ve used it in temperatures ranging from 30 to 90 degrees Fahrenheit with no noticeable change in performance. The ammo continues to cycle flawlessly.

I’ve experienced no signs of excessive wear on my revolver, and the nickel-plated casings have resisted corrosion well. Cleaning is also straightforward. The Underwood Ammo seems to burn relatively clean, leaving minimal residue.

Compared to my previous experience with heavier, lead-based .357 Magnum rounds, the Underwood Ammo offers a flatter trajectory and less recoil, which translates to improved accuracy and faster follow-up shots. It has exceeded my expectations in terms of shootability.
