The 10mm Auto cartridge occupies a unique space, bridging the gap between duty-sized handgun rounds and magnum revolver cartridges. For years, it was considered by some to be a relic, until a recent resurgence brought it back into the spotlight for its potent combination of power and manageable recoil in semi-automatic platforms. The Underwood Ammo 10mm Auto 155 Grain Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition
232 46% Off aims to capitalize on this renewed interest, promising impressive velocity and terminal performance. This ammunition immediately caught my attention due to its use of the renowned Hornady XTP bullet and the claimed high velocity.

I’ve long sought a 10mm load that offered a flat trajectory for hunting whitetail, while still providing controlled expansion for ethical kills. I was looking for a Goldilocks load that bridged the gap for black bear and feral hog defense, too. I hoped that this Underwood Ammo offering would fit the bill.

The ammunition arrived neatly packaged in a standard cardboard box, but what immediately stood out was the gleaming nickel-plated brass cases. The XTP hollow points looked consistently seated and crimped. Compared to other 10mm offerings I’ve used – like heavier 180-grain FMJ rounds from Winchester and the 200-grain hard cast loads from Buffalo Bore – the Underwood Ammo appeared sleeker and more modern.

I picked this load over the heavier options because I valued a flatter trajectory for longer-range shots and a potentially faster follow-up shot due to reduced recoil. My initial impression was one of excitement, mixed with a healthy dose of skepticism; I needed to see if the claimed velocity and terminal performance would live up to the hype.

First Use Experience

My first experience with the Underwood Ammo 10mm Auto 155 Grain Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition was at my local shooting range, using my Glock 20 with a 4.6-inch barrel. I also brought along my Springfield Armory XDm Elite 4.5″ OSP 10mm. The range was outdoors, with temperatures hovering around 65 degrees Fahrenheit and a slight breeze.

The ammunition fed flawlessly in both pistols, with no malfunctions of any kind. Recoil was noticeably sharper than with the heavier 180-grain rounds I typically use, but it was still manageable, even for rapid follow-up shots. There were no surprises other than a slightly louder report from the muzzle and more felt recoil.

Extended Use & Reliability

After several months of use, including numerous range sessions and carrying it as a defensive load while hiking, the Underwood Ammo has continued to impress. I have fired hundreds of rounds, and it has been consistently reliable, even after being subjected to jostling in a backpack for days. There were no signs of degradation or corrosion on the nickel-plated cases.

The ammunition maintained consistent accuracy, even after being stored in various conditions, including a hot vehicle during the summer. Compared to some of the cheaper bulk ammunition I’ve used in the past, the Underwood Ammo is a clear step up in terms of reliability and consistency. It certainly outperforms the generic reloads I tried once – those resulted in several misfires and inconsistent groupings.

Specifications

The Underwood Ammo 10mm Auto 155 Grain Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition features a 155-grain Hornady XTP (eXtreme Terminal Performance) bullet. The cartridge is loaded into a nickel-plated brass case, with a boxer primer and flash suppressed powder. The muzzle velocity is listed at 1500 ft/s, generating 775 ft-lbs of energy.

These specifications are significant because the lightweight bullet and high velocity promise a flat trajectory, crucial for hunting or self-defense scenarios where knowing the bullet’s path is vital. The nickel-plated case aids in reliable feeding and corrosion resistance, beneficial for those who carry their firearm in demanding environments. The flash-suppressed powder is important for maintaining night vision in low-light situations.

Performance & Functionality

The Underwood Ammo performs admirably, delivering consistent accuracy and impressive velocity. From my Glock 20, I was able to achieve consistent groupings of around 2 inches at 25 yards. The ammunition meets and, in some cases, exceeds expectations.

The ammunition’s strengths lie in its flat trajectory, manageable recoil for such a potent round, and its consistent terminal performance (based on gel testing I’ve reviewed, though I haven’t personally conducted gel tests). A potential area for improvement might be a slightly heavier bullet weight for those prioritizing deeper penetration over a flatter trajectory.

Design & Ergonomics

The nickel-plated brass casing contributes to smooth feeding and extraction, enhancing the overall shooting experience. The ammunition’s design inspires confidence.

The bright, clean look of the nickel plating is aesthetically pleasing and functional. There is no learning curve associated with using this ammunition.

Durability & Maintenance

The nickel-plated brass casings provide excellent corrosion resistance, ensuring a long shelf life even under less-than-ideal storage conditions. The ammunition is new production and boxer primed, reloadable.

This reloadability extends the life of each cartridge. Careful handling of the brass casings after firing will allow for multiple reloads, making this a cost-effective option for serious shooters.

Accessories and Customization Options

This ammunition is inherently compatible with any 10mm Auto firearm that is rated for standard pressure loads. It does not require any specific accessories or modifications to function properly.

However, to maximize the potential of this high-velocity round, a longer barrel would be beneficial to realize the full velocity potential, as the listed 1500 ft/s is likely obtained with a longer test barrel. An aftermarket recoil spring might also be desirable for some shooters to fine-tune the recoil impulse for faster follow-up shots.
