MTM Red Rifle Slip Top Ammo Box - 20 Rounds for .45-70 to .30-30

The MTM Red Rifle Slip Top Ammo Box is a durable, no-nonsense storage solution for reloaders and rifle shooters who want reliable ammunition organization. Built from tough polypropylene that resists warping, cracking, and the kind of wear that comes with regular range trips and hunting season, this 20-round box is engineered to hold classic and modern rifle cartridges from .45-70 Government down to .30-30 and many calibers in between. Whether you're stocking factory ammo, storing handloads, or organizing brass for your reloading bench, MTM's straightforward design keeps rounds secure and accessible.

The slip-top design means quick, one-handed access to your ammunition—no latches to fumble with in the field or at the bench. Rounds nest bullet-up in individual compartments, which gives you visibility and makes counting inventory simple. The box dimensions accommodate even reloaded rounds that may be slightly expanded, so if you're a handloader who pushes tolerances, you've got clearance. Many reloaders appreciate that the lid sits high enough not to touch bullets, reducing any concern about tip deformation during storage.

Built to last through seasons of use, this ammo box won't degrade or become brittle like cheaper plastics, and it stacks neatly for compact storage in a safe, truck bed, or range bag. It's the kind of unglamorous, hardworking gear that serious shooters rely on—not flashy, just dependable.
