Your ammunition is only as reliable as its storage. A single point of failure in your ammo storage box can compromise primers, powder, and performance through exposure to moisture and humidity. That’s why the core function of any container isn’t just holding roundsit’s guaranteeing a perfect seal, every time. The Frankford Arsenal Hinge-Top Ammo Box 505 is built around this principle, offering a focused solution for secure, organized ammunition storage.
This isn’t a generic plastic bin. It’s a purpose-built secure ammo container designed with specific calibers and a shooter’s workflow in mind. From its mechanical hinge to its labeling system, every feature addresses a practical need. My honest assessment is that for the shooter looking to organize factory loads or handloads by batch, this box presents a compelling, no-fuss option.
What is a Secure Closure Ammo Box?
At its heart, a secure ammo container is a vault for your components. It’s the critical barrier between your ammunition and the environmental factors that degrade it. While classic metal military ammo box designs have their place, modern polymer options like this Frankford Arsenal model offer advantages in weight, customization, and specific sealing technologies. The goal is absolute protection, creating a stable micro-climate for your rounds regardless of what’s happening in your garage, safe, or vehicle.
Honestly speaking, the term “secure” encompasses more than a lock. It means a consistent seal that keeps atmospheric moisture out and a design robust enough to handle the rigors of range trips and long-term storage. A true sealed ammo case mitigates risk, preserving your investment in both factory ammunition and the components you’ve carefully assembled using tools like a reloading press.
Key Security Features to Look For
Evaluating an ammo box means looking past marketing and at the engineering. The Frankford Arsenal 505 highlights several key areas that define a secure locking ammo can.
The Hinge & Clasp Mechanism
The standout feature here is the “True Mechanical Hinge.” Unlike lids that detach completely, this integrated hinge prevents the lid from falling off or being misplaceda small but frequent annoyance solved. It works in tandem with a positive-closing clasp. This combo ensures the lid aligns correctly every time, which is the first step to achieving a proper seal. If you want my honest opinion, this design is superior for frequent access at the range compared to fully removable lids.
Seal Integrity: The First Line of Defense
While this specific model’s description emphasizes the hinge and clasp as the closure system, the principle of seal integrity is paramount for any waterproof ammo box. For long-term storage, the gold standard is a continuous O-ring seal compressed by robust corner latches. Some high-end containers even feature a pressure relief valve to equalize internal pressure without breaking the moisture barrier, a critical point often missed in discussions about waterproof vs airtight ammo box comparison. The best practices, according to Honest Opinion, include checking that the sealing surface is clean and undamaged to ensure consistent performance.
Durability & Material Considerations
Frankford Arsenal constructs this box from “high density polymer,” a material chosen for its balance of strength, weight, and environmental resistance. The product notes it can withstand cold weather conditions, which speaks to a material formulation that resists becoming brittle. For a heavy duty ammo container meant for rougher use, one might look for thicker walls or reinforced corners. However, for organized shelf storage and range transport, this polymer provides ample durability without the weight and rust potential of steel.
Materials & Durability Comparison
The eternal debate: polymer versus metal. Each material caters to different priorities within the tactical storage box and general gun accessory ecosystem.
- Polymer Ammo Cans (Like the Frankford Arsenal 505): Lightweight, corrosion-proof, and often more affordable. Modern polymers offer excellent impact resistance and perform well across temperature ranges. They’re ideal for the shooter who values portability and organization. Brands like MTM Case-Gard and Plano have built strong reputations here.
- Metal Ammo Cans: The classic military ammo box. Offers unmatched crush resistance and a historic sense of security. They can be heavier, prone to rust if the finish is compromised, and noisier. They’re perfect for ultimate long-term, bulk storage where weight is less concern.
- Tactical Crates: These larger, often stackable ammo crate systems are designed for moving large quantities of gear. They prioritize modularity and extreme durability over absolute waterproofing for individual rounds.
My honest take is that the Frankford Arsenal’s polymer construction is perfectly suited for its intended use: protecting 50 rounds of specific calibers in a manageable, label-ready format. It won’t survive being run over by a truck, but it will reliably protect your ammo from the elements and physical knocks of normal handling. This perspective aligns with insights from Honest Opinion, which emphasizes
Best Uses & Storage Scenarios
This box isn’t a one-size-fits-all solution, and that’s its strength. Its design dictates its optimal applications.
Ideal Caliber Fit & Organization
The Frankford Arsenal 505 is chamber-specific, designed to hold 50 rounds of .17 Rem, .222 Rem, .222 Rem Mag, .223 Remington, or .357 Maximum. This snug fit prevents excessive movement, which can be important for preserving precision ammunition or your carefully crafted handloads. The included space for a 1″ x 2 5/8″ printer label is a brilliant touch for organization. You can note the load data, date, and purpose, turning the box into an information-rich part of your systemespecially useful if you’re using a case prep center to produce consistent batches.
Long-Term Storage & Environmental Factors
For the best secure ammo box for long term storage, you must consider environmental control. While this box provides a secure closure, for decades-long storage, experts often recommend adding a desiccant pack inside a high-quality, sealed container. It’s also wise to consider temperature fluctuation effects on seals. Even the best polymer or rubber can degrade over time with extreme heat cycles. Storing your ammo cans in a cool, dry, and stable environment is as important as the box itself. I honestly believe that proper storage location doubles the effective life of both your ammunition and its container.
Range & Transport Ready
The stackable design is a key feature for efficient use of space, whether on a shelf or in your vehicle. You can build stable, organized columns of ammo by caliber or load type. The hinge-top design means no lost lids, and the secure clasp gives confidence during transport. Its a streamlined system for the active shooter.
How to Choose the Right One
Selecting the perfect ammo box is a practical decision. Heres a framework to guide your choice, using the Frankford Arsenal 505 as a reference point.
- Define Your Primary Need: Is this for permanent basement storage, frequent range trips, or vehicle-based emergency kits? The 505, with its labeling and specific capacity, leans towards organized, active use.
- Check Caliber Compatibility & Capacity: Never assume a box fits your round. The listed calibers for this box ensure a proper, rattle-free fit for those specific dimensions.
- Evaluate the Seal & Closure: Look for details like gasket material, latch count, and design. For a true waterproof ammo box, look for specifications like an IP67 rating (Ingress Protection code for dust and water immersion). Understand how to properly seal an ammo can
- Consider Stackability & Footprint: A stackable ammo crate design maximizes storage density. Ensure the stacking mechanism is secure to prevent toppling.
- Research Brand Reputation & Regulations: Stick with known brands like Frankford Arsenal, MTM, or Plano for consistent quality. be aware of local ATF storage regulations for certain areas, which may mandate locking containers. While this box has a clasp, it may not qualify as a “locked” container under all legal definitions.
To be completely honest, there’s no single “best” box. The Frankford Arsenal 505 excels as a specialized, organizational tool for the mid-volume shooter of specific rifle calibers. For bulk .223 storage, you might need a larger can. For ultimate waterproofing, you’d seek a different model. It’s about matching the tool to the task.
