The Underwood Ammo 10mm Auto 155 Grain Full Metal Jacket Nickel Plated Brass Cased Pistol Ammunition
233 19% Off promises a potent blend of velocity and controlled recoil, making it an intriguing choice for both hunting and self-defense. Underwood Ammo has built a reputation for pushing the boundaries of performance, and this offering in the 10mm Auto caliber is no exception. Could this be the ideal round for taming the powerful 10mm, offering both manageable recoil and impressive ballistics?
I was looking for a 10mm round that offered a flatter trajectory for longer-range target shooting and potentially for use in handgun hunting situations. Many factory loads lean heavily on heavier projectiles, prioritizing penetration, but I wanted something that would buck the wind better and potentially expand more reliably at longer distances.
The ammunition arrived neatly packaged in a standard box. The nickel-plated brass casings gleamed, suggesting quality and corrosion resistance. Picking up a single round, it felt substantial yet noticeably lighter than the 180-grain and 200-grain rounds I typically use in my 10mm pistols.
Compared to the heavier loads from Federal and Hornady, the Underwood Ammo 155-grain FMJ seemed almost petite, but the published velocity figures hinted at serious performance. I’ve previously used heavier grain Underwood Ammo rounds with great success, but I am eager to see how this lighter, faster round performs. My initial reaction was one of cautious optimism, eager to put these rounds through their paces and see if they lived up to the hype.

First Use Experience
My initial testing took place at an outdoor shooting range with distances ranging from 7 yards to 50 yards. The conditions were sunny with a slight crosswind, providing a decent environment to evaluate accuracy and bullet drop. I fired the Underwood Ammo through my Glock 20 and my 1911 chambered in 10mm.
The most immediate impression was the reduced recoil compared to heavier 10mm loads. The pistol cycled quickly and reliably, and follow-up shots were noticeably faster. I did observe a slightly sharper report than with heavier loads, indicative of the higher velocity. No malfunctions occurred during the first 100 rounds fired.
Extended Use & Reliability
After several range sessions and roughly 500 rounds fired, the Underwood Ammo proved consistently reliable. There were no failures to feed, fire, or eject across two different 10mm platforms. The nickel-plated cases remained clean and corrosion-free, even after being stored for several weeks in my range bag.
I noticed minimal fouling in the barrels of both pistols, suggesting that the Underwood Ammo’s powder is relatively clean-burning. Compared to some of my previous experiences with budget ammunition, the Underwood Ammo consistently outperformed in terms of reliability and cleanliness. It has definitely outperformed my expectations for a lighter grain FMJ round.

- The cartridge case is made of nickel-plated brass, enhancing corrosion resistance and feeding reliability. This is particularly important in harsh environments where ammunition might be exposed to moisture.
- The advertised muzzle velocity is 1500 ft/s, generating a muzzle energy of 775 ft-lbs. These figures indicate a potent load capable of delivering significant energy on target.
- The ammunition is centerfire primed, ensuring reliable ignition. Centerfire primers are generally more consistent and less prone to misfires compared to rimfire primers.
