MTM Ammo Box 375Rem UM 375Wby Mag 50rd Flip

• 50-round capacity: keeps a full box of rifle ammunition organized in individual compartments, making it easier to sort loads, transport hunting or range ammunition, and quickly check round count.
• Polypropylene construction: the rigid plastic body resists warping, cracking, chipping and peeling, so the box stands up well to repeated use in the field, on the bench, or in long-term storage.
• Snap-Lock latch: secures the lid against accidental opening, helping prevent spilled cartridges in a pack, vehicle, or range bag.
• Textured exterior: improves grip when handling the box with wet or cold hands and helps hide everyday scuffs from transport and storage.
• Stackable flip-top design: stores neatly with other cartridge boxes and gives fast access to ammunition without taking up unnecessary space on the bench.

About the Cartridge Box Series

MTM CASE-GARD cartridge boxes are built as practical storage solutions for shooters who want ammunition kept protected, organized, and easy to handle. In MTM’s lineup, these boxes sit among the company’s long-established shooting accessories and are intended for everyone from reloaders and bench shooters to hunters who need caliber-specific storage that travels well. The series is known for its use of rigid polypropylene construction, a full-length mechanical hinge, and secure latching systems that help the boxes hold up to repeated opening, closing, and transport.

Within the range, different sizes are tailored to specific cartridge families, so each round sits in its own compartment rather than shifting loosely in bulk storage. That matters both for convenience and for protecting ammunition from unnecessary contact during transport. The flip-top models focus on straightforward access and compact storage, while the textured finish and stackable form make them easy to manage on a shelf, in a vehicle, or at the range. For shooters who keep several loads separated by caliber or purpose, MTM’s 50-round rifle boxes offer a simple system that is durable, easy to label, and well suited to regular use.

About the MTM Ammo Box 375Rem UM 375Wby Mag 50rd Flip

The MTM Ammo Box 375Rem UM 375Wby Mag 50rd Flip is a long cartridge box designed for shooters using larger rifle calibers that need more internal length than standard boxes provide. Its format suits hunting ammunition, magnum rifle loads, and carefully prepared reloads that benefit from being stored upright in individual slots instead of carried loose. With 50-round capacity, it works well as a practical range box for load development or as a field-ready storage box that keeps a full supply together and easy to count.

The body is made from polypropylene, which gives the box enough rigidity for repeated transport while resisting the cracking, peeling, or warping that can shorten the life of lighter storage solutions. The flip-top lid gives quick access to ammunition, while the Snap-Lock latch helps keep the contents secure when the box is carried in a pack, truck, or shooting kit. A textured finish improves handling and reduces the visible wear that smooth plastic often shows after regular use.

As a cartridge box for longer rifle rounds, this model is especially useful for shooters who want cleaner organization on the bench and safer transport between home, range, and hunting ground. The stackable shape helps when storing multiple loads by caliber or bullet type, and the included load labels add another practical advantage for reloaders who need clear identification of load data at a glance.
