MTM 22RD Ammo Box for .30 to .50 Caliber Rounds - Rugged Utility Military (RUM)

The MTM 22RD ammo box for .30 to .50 caliber rounds is a no-nonsense storage solution built for hunters, long-range shooters, and serious ammunition hoarders who demand durability without compromise. Whether you're stocking magnum rifle rounds, ultra-magnum cartridges, or specialty big-bore loads, this polypropylene ammo box holds 22 rounds safely and organized—and it's engineered to handle whatever conditions you throw at it.

Built from tough polypropylene, the MTM 22RD resists warping, cracking, chipping, and peeling through temperature swings and rough handling. The flip-top design gives you quick access to your ammunition without fumbling, and the material won't expand or contract with humidity changes—a critical feature if you're storing ammo long-term in a truck, range bag, or hunting camp. The construction is straightforward and field-proven: no plastic brittleness, no surprises when you need it.

This box is sized specifically for large and short-magnum rifle cartridges, including standard magnum rounds, ultra-magnum offerings, and specialized loads up to 3.84" overall length. It's a workhorse for folks running .338 Lapua, .300 Rem Ultra Mag, .375 H&H, .416 Rigby, and similar heavy-hitting calibers. If you're the kind of shooter who reloads or collects ammunition across multiple magnum platforms, the 22RD becomes part of your essential range and storage system.

Simple, utilitarian, and tough—just like the rest of your gear should be.
