MTM Case Gard J-20-LLD

The MTM Case-Gard J-20-LLD is a specific model in MTM's popular J-20 series of slip-top rifle ammunition boxes.

It's designed to hold 20 rounds of large-diameter, long rifle cartridges securely. This "LLD" variant (standing for Large Long Diameter or similar, based on sizing) accommodates bigger magnum-style rounds, such as:

• 7mm Remington Magnum
• .338 Winchester Magnum
• Similar large-bore magnum cartridges (often those with belted magnum cases or larger overall dimensions)

Key Features

• Made from tough, virtually indestructible polypropylene plastic — resistant to warping, cracking, chipping, peeling, expanding, or contracting under normal conditions.
• Features a "slip-top" (sliding lid) design for easy access while keeping rounds organized and protected.
• Transparent/smoke or clear colors (common variants include clear green or smoke) so you can see the ammo inside.
• Stackable and impact-resistant for range use, storage, or transport.
• Part of MTM's color-coded/size-varied J-20 lineup, where different suffixes (like -XS, -M, -L, -MLD, -LLD) match cartridge lengths and diameters:
  • This one is the extra-large/XL variant in the series (lid OAL around 3.84" or similar for the largest).
