MTM J20LLD41 Clear Smoke Ammo Box 338 Win Mag 7mm 20 Round Capacity

The MTM Case-Gard J20LLD41 delivers secure ammunition storage for large magnum cartridges with its precision-molded polypropylene construction. This slip-top ammo box accommodates 20 rounds of 338 Winchester Magnum, 7mm Remington Magnum, and similar large rifle cartridges in individual compartments that prevent brass damage during transport.

What Makes This Different

Unlike cardboard boxes that deteriorate with moisture, this polypropylene case maintains structural integrity through temperature extremes and humidity changes. The clear smoke finish allows instant cartridge identification while the textured exterior provides secure grip even with wet hands. MTM's living hinge design eliminates metal pins that can break or corrode over time.
