MTM Ammo Box 308 30-06 30-30 270Win 20rd Slip

• 20-round capacity: Holds a practical field or range quantity of rifle cartridges in one compact box, making it easy to separate hunting loads, practice ammunition, or carefully labeled reload batches.
• Slip-top design: The simple sliding lid gives quick access to cartridges without the bulk of a hinged case, which suits bench use, range bags, and organized storage in safes or drawers.
• Polypropylene construction: The box is made from durable polypropylene that resists cracking, warping, and everyday handling wear, helping protect ammunition during transport and repeated use.
• Long-cartridge fit: This J-20-L version is sized for cartridges such as .308 Win, .30-06, .30-30, and .270 Win, so it suits shooters who want one box format for several common long-action and similar rifle loads.
• Lightweight build: At 58.00 g, the box adds very little weight to a pack or shooting kit while still keeping cartridges together, upright, and easier to count at a glance.

About the J-20 Series

MTM CASE-GARD J-20 Series ammunition boxes are built as compact rifle cartridge storage solutions for shooters who want a simple, durable way to organize smaller quantities of ammunition. Within MTM's lineup, the J-20 family sits as a practical 20-round slip-top format, aimed at hunters, handloaders, and range users who do not need a larger 50- or 100-round case for every load.

The series is known for its polypropylene construction, which keeps weight low while standing up well to repeated transport, bench use, and storage. A key characteristic of the J-20 range is that it is offered in several internal sizes, allowing different cartridge families to be stored upright with a better fit than a one-size-fits-all box. That matters to reloaders who sort loads by bullet type, powder charge, or intended rifle, and to hunters who want a compact ammunition box that travels neatly in a pocket, pack, or vehicle compartment.

The slip-top layout is central to the series design. It keeps the box slim and easy to open, while the upright cartridge arrangement makes headstamps and load labels easier to check. In practice, the J-20 series is a straightforward storage system for keeping rifle ammunition protected, separated, and ready for use.

About the MTM Ammo Box 308 30-06 30-30 270Win 20rd Slip

The MTM Ammo Box 308 30-06 30-30 270Win 20rd Slip is the long-cartridge version of the J-20 format, intended for shooters using widely adopted rifle chamberings such as .308 Win, .30-06 Springfield, .30-30 Win, and .270 Win. Its role is straightforward but useful: it keeps a manageable 20-round supply together in a box that is easy to carry, easy to label, and easy to store alongside other load batches.

The benefit of this model is its cartridge-specific sizing. Rather than leaving long rifle rounds loose in a generic container, the J-20-L format is shaped for this cartridge class, helping keep ammunition upright and more orderly when moving between the loading bench, range bag, and gun cabinet. That is especially useful for reloaders who keep different bullet weights or powder recipes separated, and for hunters who want a dedicated box for a single rifle and load combination.

Its slip-top lid keeps the profile low and the opening motion simple, which works well when space is limited on a shooting bench or in a pack. The polypropylene body keeps the box light at 58.00 g while offering the toughness expected from a reusable ammunition case. For everyday ammunition management, this model is a practical choice for storing, transporting, and organizing common long-rifle cartridges without unnecessary bulk.
