MTM Case-Gard R100MAG10 Deluxe Multi-Caliber Rifle Ammo Box - Green Polypropylene, 100rd Capacity

The MTM Case-Gard R100MAG10 is a 100-round rifle ammo box built for shooters who demand reliable ammunition storage and protection. Whether you're stocking precision reloads, hunting rounds, or target ammunition across multiple calibers, this deluxe box keeps your investment safe in transit and at rest. The green polypropylene construction is tough enough for the truck bed or range bag, yet designed with features that matter: four protective fingers that cradle bullets in the down position to prevent tip damage—a detail that protects accuracy-critical loads from the kind of impact that can alter flight characteristics.

The R100MAG10 comes with adjustable inner trays that give you two height positions, so you're not locked into one cartridge length. Fold down the carrying handle when you need to move ammo between the range, reloading bench, or storage; stack them flat when you don't. The Snap-Lok latch keeps rounds from spilling during transport, and the textured polypropylene finish resists scuffs and won't crack, chip, or warp with temperature swings or rough handling. MTM backs the integral living hinge with a 10-year guarantee.

A pressure-sensitive load label is included so you can record your load data and sight-in notes right on the box. It's a small detail that pays off when you're running multiple loads and need to track which box holds what. For hunters, reloaders, or serious shooters who need to carry a 100-round supply without worry, the R100MAG10 delivers the protection and functionality you won't find in a basic cardboard box.

Frequently Asked Questions

What calibers will fit in the R100MAG10?

The R100MAG10 is designed as a multi-caliber box and works with rifle rounds of varying lengths, thanks to the adjustable inner trays that offer two height positions. The trays accommodate different cartridge sizes, making it suitable for hunters and reloaders who work with multiple calibers.

How does the bullet tip protection work?

When you orient rounds in the down position, four special fingers inside the box cradle the bullets and prevent them from striking the bottom. This protects bullet tips from impact damage that could alter flight characteristics—especially important for precision reloads and accuracy-sensitive loads.

Is the R100MAG10 stackable?

Yes. The box is designed for stacking and storage, and the folding carry handle folds down when you want to nest boxes together, making organization and transport efficient.
