MTM Shotshell Dry Box 100 Round Case 12 Gauge up to 3.5 inch

• 100-round capacity: Stores a full case of 12 gauge shotshells up to 3.5 inch length, keeping hunting or range ammunition organized in one compact container.
• Water-resistant O-ring seal: The sealed lid helps protect shells from rain, spray, and damp storage conditions, which is especially useful in blinds, boats, and off-season storage.
• Two removable trays: Separate trays make it easier to sort loads and access ammunition quickly without digging through a loose box.
• Removable lid and fold-down handle: The lid can be taken off to save space in tight setups, while the large handle makes the case easier to carry with gloves or cold hands.
• Lockable, impact-tolerant construction: The tough polymer body and large latch are built for repeated field use and add a measure of secure storage during transport.

About the Shotshell Dry Box Series

MTM's Shotshell Dry Box series is built for shooters who need more protection than a simple cartridge box but want a lighter, more portable alternative to a large utility crate. These cases are aimed at waterfowl hunters, clay shooters, and general shotgun users who carry ammunition into wet, muddy, or rough field conditions. The defining idea behind the series is practical weather resistance: a water-resistant O-ring sealed lid helps keep moisture away from shotshells, while the rigid molded body protects them from knocks during transport.

Across the series, MTM focuses on straightforward field usability rather than unnecessary complexity. Features such as removable shell trays, large latches, fold-down handles, and lockable tabs are designed to make the boxes easy to pack, carry, and open in hunting blinds, vehicles, or at the range. The series is especially well suited to seasonal shotgun use, where ammunition may move between home storage, travel, and wet outdoor environments. In MTM's lineup, these boxes sit as dedicated shotshell storage accessories that prioritize organization, moisture resistance, and durability for repeated use.

About the MTM Shotshell Dry Box 100 Round Case 12 Gauge up to 3.5 inch

The MTM Shotshell Dry Box 100 Round Case 12 Gauge up to 3.5 inch is configured for shotgun shooters who need to carry a substantial quantity of ammunition in a protected, orderly format. Its 100-round capacity suits long days in the field, extended practice sessions, or keeping a dedicated supply of hunting loads together and ready. Because it accepts 12 gauge shells up to 3.5 inch, it is particularly relevant for waterfowl and other applications where longer magnum loads are common.

The case uses two removable trays to keep shells arranged and easy to access. That layout helps prevent loose rounds from shifting around and makes it simpler to separate different loads when needed. The water-resistant O-ring design adds useful protection on wet days and during storage, helping keep ammunition dry in environments where rain, spray, or damp ground can be a concern. MTM also gives the box a removable lid, which is practical when space is limited in a blind or vehicle and a lower profile is preferred while shooting.

Field handling is equally important here. A generously sized fold-down handle makes the box easier to carry, and the large latch is easier to operate than a small clasp when hands are cold or gloved. The tough body is intended to withstand hard use, and the lockable design adds another layer of secure storage during transport or when the case is left with other gear.
