Keep your magnum rifle rounds organized and protected with the MTM Flip-Top Ammo Box designed for 7mm Remington Magnum, 300 Winchester Magnum, and 375 Remington Ultra Magnum cartridges. This 22-round capacity storage box is built from durable polypropylene, engineered to withstand the rigors of field use and long-term storage without warping, cracking, chipping, peeling, or expanding and contracting with temperature swings. Whether you're a dedicated magnum hunter, long-range competitor, or serious reloader, a properly organized ammo box is essential gear—and this one handles the larger cases that standard-capacity boxes can't accommodate.
The flip-top design gives you quick access to your rounds while keeping them secure during transport to the range or hunting camp. Magnum ammunition represents a significant investment, and storing it in purpose-built cases protects both your rounds and your records. The robust plastic construction resists moisture and environmental stress, so your cartridges stay in shootable condition whether you're storing them for the season or rotating stock frequently.
MTM's ammo boxes have earned trust across the shooting community for reliable, no-fuss storage. This box's compatibility with popular magnum cartridges makes it a smart choice if you're running multiple magnum rifles or simply want to match your storage to your ammunition.
