The MTM Case Gard Large 200 Rounds Rust ammunition storage box is a purpose-built cartridge organizer designed for .22 Long Rifle and .17 HMR shooters who demand secure, accessible ammo management at the range or in the field. Originally engineered for small bore rifle competitors and varmint hunters, this polymer case delivers practical compartmentalization and reliable protection for high-round-count shooting sessions.
The SB-200 configuration holds 100 rounds in the primary down position for rapid access during competitive strings of fire, with additional internal space capable of accommodating up to three 50-round boxes—making total capacity approximately 200 rounds depending on original ammunition packaging (paper or plastic). The recently retooled design now accepts .17 HMR cartridges alongside .22 Long Rifle and .22 Mach 2, expanding versatility for shooters who reload or shoot across multiple small-bore platforms. Measuring 4.5 × 2 × 8.7 inches and weighing just 0.66 lbs, the case remains portable without sacrificing load capacity.
This storage solution serves competitive rimfire shooters, small game and varmint hunters, and recreational plinkers who need to organize multiple shooting sessions or maintain inventory across different ammunition types. The MTM Case Gard's rust-resistant polymer construction protects against moisture damage and corrosion in variable field conditions, while the two-tier design system accommodates different box styles common in the ammunition industry.
MTM Molded Products Company specializes in ammunition and firearm storage solutions built for shooters who prioritize organization and durability. The SB-200 represents a refined platform with decades of field feedback, making it a standard reference for small-bore ammunition storage across competitive and hunting communities.
