The Frankford Arsenal Hinge Lid Ammo Box 45-70govt 500s&W 50 Rd (Model #514 / FA4570) is an injection-moulded, high-density polymer storage case engineered for organizing, protecting, and transporting up to 50 rounds of large-bore rifle and revolver ammunition. Designed specifically for big-bore cartridges, this passive storage accessory features an internal maximum height clearance of 2.95 inches (74.9 mm). It utilizes a true mechanical hinge rather than a flexible plastic living-hinge, ensuring the lid lies completely flat when opened for efficient reloading bench operations.

Key Features

• Mechanical Hinge Design: Built with a true mechanical hinge that remains open and lies flat to prevent the lid from springing shut during reloading or shooting.
• Secure Latching and Identification: Features a moulded, recessed latch to prevent accidental opening, a textured lid surface that fits standard 1" x 2-5/8" (25.4 mm x 66.7 mm) printer labels, and calibre sizes clearly marked on the bottom of the box.
• Stackable Profile: Structured top and bottom profiles nest together for stable, non-slip vertical stacking on shelving or inside gun safes.
• Cold-Resistant Material: Constructed from cold-resistant polymer that resists freezing and cracking in sub-zero winter temperatures or unheated storage environments.

Who is the Frankford Arsenal Hinge Lid Ammo Box 45-70govt 500s&W 50 Rd for?

• Handloaders reloading .45-70 Government — require a dedicated big-bore ammunition box that accommodates a maximum cartridge overall length of 2.95 inches (74.9 mm) while keeping up to 50 heavy-grained cartridges securely organized during bench operations.
• Shooters of .500 S&W and .460 S&W Magnum — need a heavy-duty, stackable ammunition box built from high-density polymer to securely transport and protect up to 50 high-recoil, large-bore revolver cartridges without case rattle.
• Hunters using large-bore or historic calibres — utilize classic cartridges like .50-70 Government or .50-110 WCF under 2.95 inches (74.9 mm) in length, requiring a cold-resistant ammunition box that prevents plastic cracking in freezing field conditions.

Less suitable for: Cartridges with an overall length exceeding the hard ceiling limit of 2.95 inches (74.9 mm), which will prevent the lid from closing securely, or smaller-diameter standard rifle calibres (such as .308 Win or .270 Win) that require a narrower-diameter rifle ammunition box to prevent loose rattle and tipping.
