MTM Case-Gard H50RMAG10 Deluxe Ammo Box - 50-Round Green Polypropylene for 7mm Rem/Mag & 300 Win Mag

The MTM Case-Gard H50RMAG10 is a purpose-built 50-round ammo box designed for magnum rifle rounds like 7mm Rem Mag and 300 Win Mag. If you're a long-range hunter, precision reloader, or dedicated magnum shooter, this green polypropylene storage box keeps your high-value ammunition organized, protected, and ready to grab for the range or field. The design balances serious functionality with everyday practicality—it's built to handle repeated use without the brittleness or warping that cheaper storage boxes develop over time.

What sets this box apart is its bullet-protection system. Your rounds sit point-down in the tray, cradled by four interior fingers that prevent bullet tips from striking the bottom. That matters: tip damage from loose rounds bouncing during transport can affect flight characteristics and accuracy. The tray also spaces cartridges far enough apart for one-handed removal—no fumbling or risk of dropping rounds. Belted magnum cases are the norm here, and the fold-down carry handle is shaped to let you transport them rim-up or rim-down, whichever seats your particular rounds best.

Build quality reflects MTM's reputation in ammo storage. The polypropylene shell is textured to resist scuffs and won't crack, chip, contract, or warp the way cheaper plastics do. The full-length mechanical hinge runs the entire back edge for strength and durability, and the snap-lock latch keeps the lid secure during transport so nothing spills. Stack multiple boxes without worry—the design is engineered for it.

Reloaders will appreciate the included pressure-sensitive load label. Write down your powder charge, primer lot, velocity, or sight data right on the box. When you grab it weeks or months later, all that critical information travels with your ammo.
