350 Round Ammo Locking Storage Case - Waterproof, Travel Safe

Our review of the 350 Round Ammo Locking Storage Case finds it best suited for shooters and outdoor travelers who need a compact, travel-ready solution for organizing lots of centerfire pistol cartridges. The single biggest reason to buy is its combination of high-capacity organization and a certified waterproof seal: the case stores up to 350 rounds across two trays with a center divider, while an IP67-rated rubber gasket keeps contents protected from moisture and dust during hunting trips or transport. It reads as a practical, durable ammo crate rather than a lightweight pouch.

Key Features

• Capacity: Holds 350 rounds across two trays so a large pistol ammo supply stays organized without loose boxes.
• Secure divider: The center divider protects cartridges and effectively doubles usable storage space for neat stacking and quick access.
• Waterproof protection: IP67-rated sealing plus a high-quality rubber lining helps keep bullets dry up to 1 meter underwater for short periods.
• Rugged construction: High-strength ABS shell and upgraded EVA interior provide shock and scratch protection in outdoor conditions.
• Portable design: Built-in handles and a compact 11.5 x 9.5 x 4.5 in outer size make it easy to carry into the field or stow in a vehicle.
• Wide compatibility: Sized for many common pistol cartridges including 9x19mm,.380 ACP,.38 SPL and several historic calibers for mixed collections.

Who It's For

This case is aimed at recreational shooters, hunters, and range-goers who move moderate to large quantities of pistol ammo and want a weatherproof container that organizes rounds by trays. It is also suitable for collectors who store assorted pistol calibers and appreciate a compact, impact-resistant shell.

Those who need built-in humidity control should look elsewhere: the product does not include a desiccant and the bottom compartment is not designed to fit a rectangular desiccant pack. If you require long-term underground or submarine storage, a dedicated safe with active humidity control may be a better choice.
