Getting My Hands on the MTM Flip-top Ammo Box .338 Remington UM & .416 Rigby Green RF22-LM-10
For years, keeping ammunition organized and protected has been a constant battle in various environments. Whether on a dusty workshop bench, a cluttered lab counter, or even during a rare but precious range day, loose rounds are a nuisance and a potential hazard. This need for a robust and reliable storage solution led me to the MTM Flip-top Ammo Box .338 Remington UM & .416 Rigby Green RF22-LM-10. I was looking for something specifically designed for larger magnum cartridges, a common problem when dealing with the .338 Remington Ultra Magnum and .416 Rigby, which tend to roll around and get scratched in generic containers. My previous attempts involved repurposed food containers and rudimentary cardboard boxes, none of which offered adequate protection or ease of access. I considered a few other polymer ammo can brands, but their proprietary sizing often excluded these larger calibers. Unboxing the MTM RF22-LM-10, my initial impression was one of pragmatic simplicity. The polypropylene felt solid, and the flip-top mechanism seemed promising. There was a quiet sense of satisfaction, a feeling that a common problem might finally have a sensible solution.
Real-World Testing: Putting MTM Flip-top Ammo Box .338 Remington UM & .416 Rigby Green RF22-LM-10 to the Test
First Use Experience
My testing grounds for this particular ammo box were primarily my workbench at home, where I store and prepare ammunition for various projects, and a local indoor range. The MTM Flip-top Ammo Box .338 Remington UM & .416 Rigby Green RF22-LM-10 was immediately put to the test during a session of reloading larger caliber cartridges. I found the box intuitive to use; the flip-top action opens with a satisfying click and stays open securely, providing clear access to the 22 rounds it holds. Unlike some other ammo containers that can be stiff or require significant force to open, this MTM unit was surprisingly smooth. The only minor surprise was how precisely the rounds seated; a fraction too much force and you could feel resistance, indicating a snug fit designed to prevent rattling.
Extended Use & Reliability
Over several months, this MTM ammo box has become a regular fixture on my bench. It’s been moved around, sat under other equipment, and even survived an accidental tumble onto a concrete floor with no ill effects. The polypropylene material has proven its resilience, showing no signs of warping, cracking, or chipping despite the constant exposure to varying temperatures and humidity levels within my workshop. Cleaning is straightforward; a quick wipe with a damp cloth is usually sufficient, and even after multiple uses loading and unloading, there are no lingering metal shavings or dust. Compared to older plastic ammo boxes I’ve owned, which often developed brittle hinges or became difficult to latch, this RF22-LM-10 model feels substantially more robust and reliable. It hasn’t shown any signs of performance degradation, maintaining its integrity and function consistently.
Breaking Down the Features of MTM Flip-top Ammo Box .338 Remington UM & .416 Rigby Green RF22-LM-10
Specifications
The MTM Flip-top Ammo Box .338 Remington UM & .416 Rigby Green RF22-LM-10 is engineered with specific needs in mind. It boasts a capacity of 22 rounds, which is an optimal number for handling larger cartridges without excessive bulk. The material is polypropylene, known for its excellent chemical resistance and durability, ensuring it won’t warp, crack, chip, peel, expand, or contract under normal conditions. This is a critical feature for ammunition storage, as environmental stability is key to preserving powder integrity and preventing case deformation. The color is a standard Green, a common choice in the firearms and outdoor gear community for its visibility without being overly conspicuous.
The dimensions are designed to accommodate cartridges like the .338 Remington Ultra Magnum and .416 Rigby. While exact dimensions aren’t listed, the product description clearly states it’s designed for the WSM and Ultramag series, which includes these powerful rounds. The snap-shut, flip-top lid mechanism is a user-friendly design that provides quick and secure access to your ammunition. It effectively keeps dust, dirt, and moisture out, safeguarding your valuable rounds. This is a significant advantage over open-top trays or less secure containers.
Performance & Functionality
In terms of its primary function, protecting and organizing ammunition, this MTM box performs admirably. The individual slots are molded to hold each cartridge securely, preventing them from shifting and rubbing against each other. This is particularly important for magnum rounds where bullet tips can be more delicate or exposed. I found that the 22-round capacity is practical for a session at the range or for storing a specific load type. The flip-top lid seals well enough to offer good protection against common workshop or range debris.
A notable strength is its durability; the polypropylene construction seems nearly impervious to the casual bumps and scrapes of a workshop environment. Its main function is straightforward and it excels at it. The only potential functional limitation, which is more of a characteristic of larger cartridges, is noted in some user feedback: that larger rounds like the .338 Lapua might require orientation changes. While this specific model is designated for .338 Remington UM and .416 Rigby, it highlights that some very long cartridges might push the design limits, though for its intended calibers, it functions flawlessly.
Design & Ergonomics
The design of the MTM Flip-top Ammo Box .338 Remington UM & .416 Rigby Green RF22-LM-10 is focused on practical utility rather than complex aesthetics. The green polypropylene finish is functional and resilient, resistant to scuffs and marks. The flip-top lid is perhaps the most significant ergonomic feature; it opens smoothly with a single hand and stays open, allowing for easy placement or removal of cartridges. There’s no learning curve involved; it’s immediately intuitive. The textured surface offers a decent grip, even with slightly greasy hands, preventing accidental slips.
The internal tray is precisely molded, ensuring each cartridge sits snugly in its designated spot. This design prevents the common issue of rounds jangling around or becoming mixed up. While it might not possess the refined look of some premium metal ammo cans, its strength lies in its simplicity and robust construction, making it perfectly suited for its intended environment. The overall feel is one of solid, no-nonsense functionality.
Durability & Maintenance
This ammo box is built for the long haul, especially considering its polypropylene construction. For its intended use – storing ammunition in workshop, lab, or range settings – it’s designed to be highly durable. I’ve seen similar MTM products withstand years of abuse. For a 22-round capacity box of this type, it’s designed to be a reusable, long-term storage solution.
Maintenance is exceptionally easy. A quick rinse under water or a wipe-down with a damp cloth is usually all that’s needed to keep it clean. There are no complex parts or mechanisms to worry about. Potential failure points are minimal; the hinge mechanism for the flip-top lid is usually the most stressed component in such designs, but MTM typically engineers these for significant longevity. Unlike softer plastics that can become brittle with age or UV exposure, this material holds up well. It’s designed to be a workhorse, not a delicate instrument.
Accessories and Customization Options
The MTM Flip-top Ammo Box .338 Remington UM & .416 Rigby Green RF22-LM-10 is a standalone product with no specific accessories included. Its customization options are limited to its primary function: holding ammunition. However, the design itself is part of a broader MTM product line, meaning that other MTM ammo boxes and storage solutions are available.
The compatibility with other brands is less of a factor here; its specific purpose is to house .338 UM and .416 Rigby cartridges. While you could potentially fit other cartridges of similar dimensions into the slots, it’s designed and optimized for its stated calibers. There are no add-on components for this particular model. The emphasis is on the product’s inherent design and materials for reliable ammunition storage.
