Let’s Talk About Underwood Ammo .300 AAC Blackout 125 Grain Polymer Tipped Spitzer Nickel Plated Brass Cased Rifle Ammunition 418
The Underwood Ammo .300 AAC Blackout 125 Grain Polymer Tipped Spitzer Nickel Plated Brass Cased Rifle Ammunition 418 promises a potent combination of accuracy, stopping power, and reliability. Manufactured by Underwood Ammo, this round is designed for a variety of applications, ranging from hunting and predator control to self-defense. Its polymer-tipped spitzer bullet ensures rapid expansion upon impact, maximizing terminal ballistics, while the nickel-plated brass casing guarantees smooth feeding and corrosion resistance.
I was searching for a versatile .300 Blackout round that could perform well in both my AR pistol for home defense and my bolt-action rifle for hog hunting. I needed ammunition that offered consistent performance, reliable expansion, and minimal risk of malfunctions in either platform. The combination of a polymer-tipped bullet, nickel-plated brass, and Underwood Ammo’s reputation for quality control drew me to this specific load.
Upon opening the box, the rounds presented a clean, uniform appearance. The nickel-plated brass casings were noticeably slick, and the polymer tips on the spitzer bullets looked precisely seated. The weight and balance of the cartridges felt consistent, inspiring confidence in their quality.
Compared to other .300 Blackout offerings from companies like Hornady and Barnes, the Underwood Ammo stood out for its specific blend of features. Hornady’s Black series is known for its affordability, but I was willing to pay a premium for the enhanced corrosion resistance and feeding reliability offered by the nickel-plated brass. Barnes’ VOR-TX ammunition uses all-copper bullets for improved penetration, but I preferred the rapid expansion promised by the Underwood Ammo’s polymer-tipped design for my intended use cases. My initial impression was one of cautious optimism. I was eager to see if the ammunition lived up to its promises on the range and in the field.
Real-World Testing: Putting Underwood Ammo .300 AAC Blackout 125 Grain Polymer Tipped Spitzer Nickel Plated Brass Cased Rifle Ammunition 418 to the Test
First Use Experience
I initially tested the Underwood Ammo .300 AAC Blackout 125 Grain Polymer Tipped Spitzer Nickel Plated Brass Cased Rifle Ammunition 418 at an indoor shooting range and later during a hog hunt in Central Texas. At the range, I used both my 8.5-inch AR pistol and my 16-inch bolt-action rifle to evaluate accuracy and function. The ammunition performed flawlessly in both firearms, exhibiting consistent cycling in the AR pistol and smooth chambering in the bolt-action rifle.
During the hog hunt, the weather was damp and muddy. Despite the challenging conditions, the Underwood Ammo remained reliable. The nickel-plated casings showed no signs of corrosion, and the rounds chambered and fired without issue.
The rounds grouped consistently within 1.5 inches at 100 yards with the bolt-action rifle, and approximately 2.5 inches with the AR pistol. There were no failures to feed, fire, or eject.
Extended Use & Reliability
After several months of consistent use, the Underwood Ammo .300 AAC Blackout 125 Grain Polymer Tipped Spitzer Nickel Plated Brass Cased Rifle Ammunition 418 has proven to be remarkably reliable. I’ve fired approximately 500 rounds through my firearms, with no malfunctions to date. The nickel-plated brass continues to resist corrosion, even after being stored in humid environments.
The ammunition exhibits minimal signs of wear and tear. The bullet seating remains consistent, and the primers show no signs of degradation. Cleaning is straightforward, and the nickel-plated casings wipe down easily, minimizing residue buildup.
This ammunition significantly outperforms other budget .300 Blackout rounds I’ve used in the past. The consistent accuracy and reliable expansion provide a noticeable advantage in both target shooting and hunting scenarios.
