The Underwood Ammo 10mm Auto 165 Grain Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition promises serious power and reliability. Coming from Underwood Ammo, a company known for pushing the boundaries of cartridge performance, this offering immediately piqued my interest. It boasts a 165-grain jacketed hollow point bullet, nickel-plated brass casing, and a blistering 1400 ft/s muzzle velocity, promising a potent combination for hunting and self-defense.

I’ve been a 10mm Auto enthusiast for years, primarily because of its flat trajectory and knockdown power compared to other semi-automatic pistol cartridges. My usual load for deer hunting was a heavier 200-grain hard cast, but I wanted to try something lighter and faster for whitetail, and potentially for personal defense against larger predators while hiking in grizzly country. This Underwood Ammo load seemed to fit the bill perfectly.

Upon receiving the package, the first thing I noticed was the professional packaging, very reassuring for high-performance ammunition. The nickel-plated cases shone, projecting an image of quality and corrosion resistance, and the jacketed hollow points looked precisely formed. Picking up a round, it felt substantial, promising controlled expansion and deep penetration.

I’ve used similar defensive rounds from Federal and Hornady, but Underwood Ammo consistently delivers higher velocities and energy figures, often at a more competitive price point. I selected this over similar rounds because I was looking for that extra margin of power, especially in a cartridge designed for demanding applications. I wanted to maximize the potential of the 10mm round.

My initial impression was excitement mixed with a healthy dose of respect; this ammunition clearly wasn’t designed for plinking. It seemed to be a purpose-built round for serious applications, and I was eager to see if it lived up to the hype at the range and in the field. The promise of a 22% discount only sweetened the deal, making it a compelling purchase.

First Use Experience

My first outing with the Underwood Ammo 10mm Auto 165 Grain Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition was at my local outdoor range, under clear skies and moderate temperatures. I was using my Glock 20, a platform known for its reliability and capacity in the 10mm chambering. The plan was to chronograph the rounds, assess accuracy at varying distances, and evaluate felt recoil.

The Underwood Ammo performed admirably. The ammunition consistently produced velocities close to the advertised 1400 ft/s, averaging around 1385 ft/s across ten rounds, a negligible difference. Accuracy was excellent, producing sub-2-inch groups at 25 yards, which is far better than I typically shoot with defensive ammo.

The recoil was noticeably stout, more significant than the standard 180-grain loads I usually practice with. This was expected given the increased velocity and energy, but it remained manageable in the Glock 20 platform. The only minor issue was a slightly sharper muzzle flash compared to other ammunition.

Extended Use & Reliability

After several months of use, including multiple range sessions and a deer hunt, the Underwood Ammo 10mm Auto 165 Grain Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition has proven to be exceptionally reliable. I experienced zero malfunctions across several hundred rounds, a testament to the quality components and loading process. The nickel-plated cases have held up well, showing no signs of corrosion or tarnishing even after exposure to damp conditions.

The ammunition has proven to be quite durable. While I haven’t subjected it to extreme abuse, it has been stored in a variety of conditions, from hot car trunks to cold hunting packs, without any degradation in performance. Cleaning the pistol after shooting Underwood Ammo has been straightforward.

Compared to my previous go-to hunting load, the Underwood Ammo offered a flatter trajectory, which translated to less holdover at longer distances, a crucial factor in hunting situations. While I didn’t harvest a deer with it this season (the opportunity never presented itself), I have no doubt in its effectiveness based on its terminal ballistics testing I observed and its performance on target. It has certainly exceeded my expectations as a high-performance 10mm load.
