MTM Deluxe Ammo Box Handle WSM WSSM Ultra Mag 100 Rounds Clear Blue
The MTM Deluxe Ammo Box Handle WSM WSSM Ultra Mag is a 100-round ammunition storage solution built for reloaders and shooters who demand reliable protection for precision loads. This clear blue polypropylene box is purpose-built to handle the larger magnum cartridges—including Winchester Short Magnums, Winchester Super Short Magnums, and ultra-magnum rounds—while safeguarding your ammunition during storage and transport.
What sets this ammo box apart is its dual-position tray system and bullet-tip protection design. The adjustable inner trays can be rotated to two different height positions, letting you accommodate varying cartridge lengths within the same box. Rounds can be stored bullet-up or bullet-down depending on your preference and cartridge type—when bullets point downward, the box's special fingers keep them from contacting the bottom, preventing the tip damage that can affect flight characteristics. This thoughtful engineering makes it ideal for anyone running a loading bench who cares about ammunition consistency.
Built to last, the box is molded from durable polypropylene with a scuff-resistant textured finish and comes backed by MTM's 10-year guarantee. The integrated handle makes it convenient to move boxes between your safe, range bag, or truck bed, while the mechanical hinge and stackable design let you organize multiple calibers without eating up shelf space. A load label included on the box helps you track what's inside. Made in the USA, this is ammunition storage engineered for shooters who understand that protecting your reloads is protecting your investment in accuracy.
