MTM Case-Gard J-20 Slip-Top Ammo Box 7mm Rem Mag/.338 Win Mag 20-Round Red Polypropylene

The MTM Case-Gard J-20 Slip-Top Ammo Box is a purpose-built rifle ammunition carrier sized specifically for the longer, larger-diameter cartridges of the 7mm Remington Magnum and .338 Winchester Magnum. Part of the J-20 series, this 20-round slip-top box keeps magnum-length rifle rounds secure and organized at the bench, in transit, or in the safe.

The box is molded from virtually indestructible polypropylene in a bright red translucent finish, so it is easy to spot on a cluttered shooting bench. Polypropylene will not warp, crack, chip, peel, expand, or contract with temperature swings, making it a reliable long-term storage solution for reloaded or factory ammunition. The simple slip-top lid slides on and off for quick access to the contents while keeping rounds contained, and the J-20's overall footprint is matched to magnum-length bottlenecked cases so the rounds stack neatly without tipping.

The J-20-LLD is one of five size variants MTM offers across the J-20 Slip-Top line, covering everything from the 220 Swift and 25-06 up through the largest magnums. Whether you are loading for an upcoming hunt, organizing a stash of magnum brass, or just keeping loose rounds corralled at the range, this is a classic, no-nonsense storage box built to last.
