Keep your rimfire and magnum rifle ammunition organized, protected, and ready to go with the MTM Flip-Top Ammo Box. Designed to safely store 22 rounds of larger-capacity cartridges like the 7mm WSM, 300 WSM, and 45-70 Gov't, this durable polypropylene storage case is built for hunters and shooters who demand reliable ammo organization without breaking the bank. Whether you're prepping for a big-game hunt, stocking your reloading bench, or simply keeping your range bag tidy, this flip-top box keeps your rounds secure and your gear in one place.
MTM has engineered this ammo box to handle tough field conditions and garage storage alike. The rigid polypropylene construction resists warping, cracking, chipping, and peeling—the common failures that plague cheaper boxes. Since ammunition storage directly affects both safety and performance, choosing a robust case like this one pays dividends over time. The flip-top design gives you quick access without fumbling with lids, and the compact footprint stacks neatly in safes, range bags, and truck beds.
If you shoot magnum cartridges or reloading-length rounds with maximum overall lengths (OAL) up to 3.14 inches, this box will accommodate them. The 22-round capacity makes it ideal for folks who prefer smaller, more portable storage units rather than bulk-ammo cans, especially for premium or specialty loads where individual round management matters.
| Capacity | 22 rounds |
| Material | Polypropylene |
| Max OAL | 3.14 inches |

Yes. The MTM flip-top box is specifically designed for the 7mm WSM, 300 WSM, and 45-70 Gov't, and will accommodate cartridges with a maximum overall length up to 3.14 inches. Always verify that your loaded ammunition's OAL does not exceed this limit.
This box is optimized for 7mm WSM, 300 WSM, and 45-70 Gov't. It is also compatible with other large-magnum and rimmed cartridges that fit within the 3.14-inch maximum overall length, including 8x56 Hungarian, 9.3x62, 9x57, and other similarly sized rounds.
The 22-round capacity and sturdy polypropylene construction make this box a popular choice for storing loaded reloading samples and sorted ammunition by lot or bullet type. The flip-top design allows convenient access to your organized rounds at the reloading bench.
The polypropylene material is engineered to resist warping, cracking, chipping, and peeling, making it durable for long-term storage in vehicles, safes, and outdoor conditions. Proper storage away from extreme heat will help maintain the box's integrity over its lifespan.
