I’ve been chasing the ultimate hog hunting round for years. I wanted something that would drop them in their tracks, minimizing suffering and the chance of them running into thick brush.
The arrival of the brown cardboard box was unassuming, but the contents promised otherwise. The brass cases gleamed, and the FMJ bullets looked menacingly effective; the Underwood Ammo reputation for quality appeared well-deserved at first glance. This felt like serious firepower.
I considered several other options, including some heavier grain loads from other manufacturers, and even considered reloading my own. I ultimately chose the Underwood Ammo 50 Beowulf 350 Grain Full Metal Jacket Brass Cased Rifle Ammunition because of Underwood’s reputation for quality control and consistency, combined with the attractive discounted price.
Initially, I was excited by the sheer potential this ammunition offered. The potential for massive knockdown power was undeniable, tempered only by the knowledge that .50 Beowulf rounds can be finicky in some AR platforms.

First Use Experience
My first test took place at my usual shooting range, a controlled environment where I could focus on function and accuracy. I brought my Alexander Arms .50 Beowulf AR-15, thoroughly cleaned and oiled, ready for some serious action. The weather was dry and mild, perfect for a comfortable range day.
The first few rounds cycled smoothly, producing a satisfying boom and noticeable recoil. The muzzle climb was significant, a reminder of the power being unleashed.
However, by the fifth round, I encountered my first malfunction – a failure to eject, resulting in a stovepipe jam. This raised immediate concerns.
Extended Use & Reliability
After several weeks of intermittent testing and meticulous rifle cleaning, the inconsistent performance persisted. Some range trips were flawless; others were plagued by failures to eject, sometimes multiple times per magazine. The brass cases showed no obvious signs of overpressure.
Durability seemed fine, as the rounds themselves held up well in storage and during handling; however, the reliability issues overshadowed everything else. Cleaning the rifle thoroughly after each session became a necessity to try to mitigate the ejection issues.
Compared to other .50 Beowulf ammunition I’ve tested (specifically some Hornady rounds), the Underwood Ammo was noticeably less consistent in cycling. While the Hornady rounds were more expensive, they fed and ejected flawlessly.

Specifications
The Underwood Ammo 50 Beowulf 350 Grain Full Metal Jacket Brass Cased Rifle Ammunition boasts some impressive specifications. It is chambered in .50 Beowulf, designed for AR-15 platforms with appropriate modifications.
- Caliber: .50 Beowulf: A large-bore round designed for maximum stopping power at shorter ranges.
- Bullet Weight: 350 grain: Offers a balance between manageable recoil and significant energy transfer.
- Bullet Type: Full Metal Jacket (FMJ): Provides reliable feeding and penetration.
- Cartridge Case Material: Brass: Allows for reloading and reliable extraction (in theory).
- Muzzle Velocity: 1775 ft/s: Delivers significant kinetic energy upon impact.
- Muzzle Energy: 2449 ft-lbs: Quantifies the massive force delivered by each round.
- Application: Hunting: Suitable for taking down medium to large game.
- Number of Rounds: 20: A standard box quantity for rifle ammunition.
- Primer Style: Centerfire: Ensures reliable ignition.
- G1 Ballistic Coefficient: 0.235: Indicates relatively rapid velocity loss over distance, typical of large-caliber pistol cartridges adapted to rifles.
- Lead Free: No: Traditional lead core bullet construction.
- Manufacturer: Underwood Ammo: Known for producing high-quality, often specialized ammunition.
These specifications matter because they define the round’s intended use and performance characteristics. The high muzzle energy and large bullet weight suggest significant knockdown power, while the FMJ design ensures reliable feeding in semi-automatic rifles.
Performance & Functionality
When the Underwood Ammo 50 Beowulf 350 Grain Full Metal Jacket Brass Cased Rifle Ammunition functioned correctly, the performance was undeniably impressive. The recoil was stout but manageable, and the rounds grouped reasonably well at 50 yards, within a 3-inch circle.
However, the inconsistent cycling overshadowed the raw power. The frequent failures to eject seriously hampered usability and reliability.
The ammunition promises exceptional power, and delivers on that promise when it functions; however, the reliability issues are a significant detractor. The potential is there, but the inconsistency undermines confidence in the product.
Design & Ergonomics
The ammunition’s design is straightforward: a typical brass-cased cartridge with a Full Metal Jacket (FMJ) bullet. The brass casing appears to be of good quality, and the bullet is consistently seated.
There’s no inherent ergonomic aspect to ammunition beyond ensuring reliable feeding and extraction. The issues I experienced suggest potential shortcomings in manufacturing tolerances or powder load consistency, impacting cycling reliability.
Durability & Maintenance
Ammunition is inherently durable in the sense that it’s designed for single use. Proper storage in a cool, dry environment is crucial to prevent degradation of the powder and primer.
There is no maintenance required for ammunition, beyond proper storage. The brass cases could be reloaded, if one is so inclined.
Accessories and Customization Options
Ammunition itself doesn’t typically have accessories, but it does dictate rifle setup. To best utilize this ammunition, one should have a properly functioning AR-15 platform specifically chambered in .50 Beowulf.
Optics are highly recommended for maximizing accuracy with this powerful round. A quality red dot sight or low-power variable optic would be ideal.

The Underwood Ammo 50 Beowulf 350 Grain Full Metal Jacket Brass Cased Rifle Ammunition presents a mixed bag. The raw power and potential are undeniable, but the inconsistent cycling issues are a significant drawback.
The discounted price makes it an attractive option, but the reliability problems detract from the overall value. I’m left questioning if the savings are worth the potential for malfunctions.
