Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag Review

Field Test Review of the Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag

For anyone who loads their own ammunition or frequently transports rounds for high-powered rifles, the need for reliable, robust storage is paramount. I recently found myself needing a dedicated solution for my .300 Remington Ultra Magnum and similar magnum-length cartridges, a caliber that demands a bit more headspace than standard rifle rounds. This led me to explore options, and the Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag stood out for its specified dimensions and the manufacturer’s reputation for durable polypropylene products. I’d previously used smaller Berry’s boxes for pistol rounds and found them to be perfectly adequate, so I approached this larger caliber variant with a good degree of optimism. My old, mismatched plastic containers and makeshift solutions were becoming a liability, leading to potential damage and disorganization. Upon receiving this ammo box, my initial impression was positive; the high impact polypropylene felt substantial, and the latch mechanism seemed robust enough for regular use. While I briefly considered generic clear plastic cases from a big-box sporting goods store, the specific caliber fit and the promise of Berry’s Manufacturing’s build quality tipped the scales. My immediate reaction was one of cautious satisfaction, anticipating an end to my ammunition-related clutter.

Real-World Testing: Putting Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag to the Test

My testing environment for this ammo box was primarily my dedicated reloading bench and, subsequently, the dusty confines of my range bag. I loaded it up with freshly reloaded .300 RUM rounds, ensuring they seated correctly in the individual cells. The initial fill was straightforward; the rounds slid in with satisfying ease, and the case felt secure. The translucent nature of the box allowed me to quickly verify the contents without needing to unlatch it, a small but appreciated convenience.

First Use Experience

The primary scenario for this box was storing and transporting a specific batch of reloaded ammunition to the shooting range. I subjected it to the usual jostling of being placed in and out of my vehicle, and then the more vigorous shaking that occurs inside a packed range bag. The Berry’s Manufacturing box performed admirably. Its stackable design meant it fit snugly alongside other gear without shifting excessively. Even when exposed to the occasional gust of wind carrying fine dust at the range, the latch held firm, preventing any ingress. I found its operation entirely intuitive; no complex instructions were needed. Simply unlatch, load, and re-latch – it’s a simple, effective process.

Extended Use & Reliability

After several weeks of use, involving multiple trips to the range and frequent access on my reloading bench, the ammo box continues to impress. It has held up exceptionally well to repeated opening and closing of the latch, showing no signs of premature wear. The high impact polypropylene has proven resilient, with no observable cracks, warping, or chipping, even after an accidental drop onto a concrete floor from about waist height. Maintenance is practically non-existent; a quick wipe with a dry cloth is all that’s ever been needed. Compared to some flimsier, less expensive alternatives I’ve used in the past, this Berry’s Manufacturing unit feels built to last. Those other boxes often developed stiff hinges or cracked lids after only a few months, a fate this one seems destined to avoid.

Breaking Down the Features of Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag

Specifications

The Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag is engineered to accommodate specific magnum-length cartridges. Its core construction material is high impact polypropylene, chosen for its excellent resistance to cracking, chipping, warping, expansion, or contraction, crucial for maintaining ammunition integrity in varying conditions. Each cell within the box is dimensioned at approximately 3.85″ OAL (Overall Length) x .66″ (diameter). This precise sizing is specifically designed for cartridges such as the .300 Remington Ultra Magnum, 7mm Remington Ultra Magnum, .300 H&H Magnum, .338 Remington Ultra Magnum, .338 Lapua Magnum, .378 Weatherby Magnum, .460 Weatherby Magnum, and the .500 A-Square. The box itself holds 20 rounds, making it a practical choice for range sessions or field use without unnecessary bulk. It is available in three colors: Blue Smoke, Clear, and Hunter Orange, offering a degree of personalization and visibility. This model also carries a lifetime warranty, a testament to Berry’s Manufacturing‘s confidence in their product’s durability.

The generous cell dimensions are a critical specification. For cartridges like the .300 Ultra Mag, which have a longer overall length, insufficient space can lead to bullets pressing against the box, potentially altering the seating depth of your reloads. The .66″ diameter allows ample room for cartridges with larger base diameters and belt configurations, like the H&H and Weatherby magnums listed. The 20-round capacity strikes a good balance; it’s enough ammunition for a focused range trip without making the box overly large or heavy, especially when compared to higher-capacity boxes that might hold 50 or 100 rounds but become unwieldy. The choice of translucent polypropylene is also a functional design element, allowing users to quickly identify the contents and quantity without opening the box, saving time and reducing exposure to the elements. Furthermore, the stackable design is a significant ergonomic feature, allowing for neat organization on a shelf or in a range bag. Finally, the lifetime warranty provides peace of mind, suggesting this is not a disposable item but an investment in long-term storage.

Performance & Functionality

The primary job of the Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag is to securely hold and protect ammunition for specific magnum rifle calibers. In this regard, it performs exceptionally well. The individual cells are perfectly sized to prevent rattling and keep cartridges upright and protected. I experienced zero issues with rounds tipping or becoming jammed, even when the box was inverted or subjected to moderate shaking. The latch system is secure and provides a satisfying click when closed, indicating a firm seal that prevents accidental opening.

Its main strength lies in its precise fit for the intended cartridges. Unlike some generic boxes where longer rounds might barely fit or protrude slightly, these cells provide ample clearance. This ensures that bullet tips are not deformed and primer edges are not exposed. A potential weakness, though minor for its intended purpose, could be the lack of significant shock absorption beyond the material itself; for extreme conditions requiring padded protection, further measures might be considered. However, for its intended use of organized storage and transport, it exceeds expectations, offering reliability far beyond its modest price point.

Design & Ergonomics

The design of this ammo box is fundamentally practical, prioritizing function over aesthetics, though the available colors add a touch of personality. The high impact polypropylene gives it a solid, reassuring feel; it doesn’t feel flimsy or cheap. The surface has a slight texture that aids in grip, preventing it from slipping easily from your hands, especially when wearing gloves or if your hands are slightly damp. The latch mechanism is straightforward and robust, easy to operate with one hand if necessary, though it benefits from two.

The stackable nature of the design is a significant ergonomic win. The base of one box mates securely with the lid of another, allowing for stable stacking that conserves space. This is a huge advantage on a crowded reloading bench or within a packed gear locker. The translucent material, while not perfectly clear, is sufficiently transparent to identify the caliber and count the rounds at a glance, which is a thoughtful touch that improves usability. There’s no real learning curve; it’s an intuitive design that anyone familiar with basic storage containers can immediately use.

Durability & Maintenance

In terms of durability, this Berry’s Manufacturing ammo box is built to endure regular use for a considerable lifespan. As mentioned, the high impact polypropylene material is highly resistant to stress and impact. I anticipate this box will last for many years, likely outliving many of the cartridges it holds, assuming reasonable care. Maintenance is virtually non-existent. A quick rinse with water and drying, or even just a wipe-down with a cloth, is sufficient to keep it clean. There are no complex parts to disassemble or lubricate.

The most likely point of failure for any plastic container is the latch or hinge mechanism over extended, aggressive use. However, the design here appears sturdy, with thicker plastic at stress points. I have not observed any signs of cracking around the hinge pins or stress fractures on the latch components. Potential users should, however, be mindful of prolonged exposure to extreme UV radiation, which can degrade plastics over time, though this is a general concern for all plastic products left outdoors.

Accessories and Customization Options

The Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag itself is quite self-contained and doesn’t typically come with additional accessories in the way a firearm or electronic device might. Its primary “accessory” is its stackable design, which integrates seamlessly with other boxes of the same type from Berry’s Manufacturing. The main customization option lies in the choice of color: Blue Smoke, Clear, or Hunter Orange. Each color serves a slightly different purpose; Clear offers maximum visibility of contents, Blue Smoke is a bit more discreet, and Hunter Orange provides excellent visibility for quick identification in various environments, which can be a safety feature.

There are no specific aftermarket parts or modifications readily available or necessary for this type of product. Its function is straightforward and well-executed in its standard form. Compatibility with other brands’ ammo boxes is generally low; these types of containers are usually designed to nest specifically within their own product line. For users requiring enhanced protection for high-value ammunition, the most common “accessory” would be to place this durable box within a larger, padded Pelican-style case, but the box itself is designed to be the primary protective layer for the rounds.

Pros and Cons of Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag

Who Should Buy Berry’s Manufacturing Ammo Box #112 – .300 Ultra Mag?

This ammo box is an ideal choice for reloaders who meticulously craft their magnum rifle ammunition and need secure, organized storage for their creations. It’s also perfect for competitive shooters and hunters who frequently transport specific loads of powerful cartridges like the .300 RUM, .338 Lapua Magnum, or various Weatherby magnums to the range or afield. Anyone who values organization and protection for their specialized ammunition will find this box highly beneficial.

Conversely, those looking for a generic, one-size-fits-all ammo box for a wide variety of calibers should look elsewhere. If you primarily shoot standard .223 or .308, this box’s cell dimensions will be overkill and may not even fit your ammunition correctly. It is also not suitable for those seeking high-capacity bulk storage, as it’s limited to 20 rounds. Essential accessories are minimal, but ensuring you select the correct caliber box from Berry’s Manufacturing is paramount.
