Buyer’s Guide: What to Consider
Choosing the right ammo can depends on your specific needs. Consider the material, size, seal quality, locking options, and portability. This guide helps you evaluate these factors to make an informed decision.
- Material: Steel vs. Plastic: Steel cans offer maximum durability and impact resistance, ideal for rough handling and long-term storage. Plastic cans are lighter, rust-proof, and often more affordable, but may crack under extreme cold or heavy impacts. Consider your environment and how often you move the can.
- Size and Capacity: Ammo cans come in 30-caliber and 50-caliber sizes. 30-caliber cans are smaller and easier to carry, holding around 6-8 boxes of ammo. 50-caliber cans are larger, suitable for bulk storage or larger calibers. Choose based on the amount of ammo you need to store and your storage space.
- Waterproof and Dustproof Seals: Look for cans with rubber gaskets or O-ring seals to keep moisture and dust out. A good seal is crucial for preventing corrosion and ensuring your ammo remains reliable. Test the seal by closing the lid and checking for any gaps.
- Locking Mechanisms: Some cans have padlock tabs, allowing you to secure the contents with a lock. This is important for safety, especially if you have children or want to prevent unauthorized access. Consider cans with dual latches for a more secure closure.
- Portability and Stackability: If you need to transport ammo, look for cans with comfortable handles and tie-down points for ATVs or vehicles. Stackable designs save space in storage. Some crates include multiple cans for easier carrying, which can be more convenient than individual cans.
Conclusion
Selecting the best ammo can comes down to balancing durability, capacity, and convenience. For rugged steel protection, HARDROCK cans are excellent. For lightweight versatility, MTM plastic cans offer great seals and stackability. Sheffield provides space-saving designs, while Plano offers a budget-friendly lockable option.
Ultimately, the right choice depends on your storage environment and how you plan to use the can. Evaluate your priorities and pick the one that fits your shooting lifestyle.
