The MTM Case-Gard 308 Ammo Can holds 400 rounds of 308 Winchester ammunition (7.62 NATO) securely, with 4 RM-100 ammo boxes that fit inside to keep each cartridge separate from the rest. A heavy-duty latching system and 2 padlock tabs provide security against unwanted entry and spillage, while a tongue and groove O-Ring sealed lid keeps out water and dirt. A comfortable handle carries heavy loads and folds flat while stacking cans; molded-in stacking ridges keep cans from toppling over. The RM-100 boxes have a mechanical hinge and a snap-lock latch. Both the MTM Case-Gard 308 Ammo Can and the RM-100 ammo boxes are constructed of rugged polypropylene that will not warp, crack, chip, or peel. The included sticker labels allow shooters to accurately record different loads in each of the 4 boxes. The MTM Case-Gard 308 Ammo Can is also compatible with other similar-sized centerfire cartridges including 243 Winchester, 250 Savage, 25-35, and 6.5 Creedmor.Manufacturer model #: ACC308.
