Factors to Consider when Choosing Ammo Boxes

Durability

When selecting an ammo box, durability is crucial. Look for boxes made from sturdy materials like metal or high-impact plastic. Ensure that the box can withstand rough handling, moisture, and temperature changes to protect your ammunition during storage and transportation.

Size and Capacity

Consider the size and capacity of the ammo box based on your specific needs. Determine the number of rounds you typically carry or store and choose a box that can accommodate that quantity comfortably. Keep in mind that different ammunition sizes may require different box sizes, so select one that fits your specific caliber.

Security Features

Ammo boxes with secure closures, such as latch systems or padlock compatibility, are essential for keeping your ammunition safe and preventing unauthorized access. Look for boxes with reliable locking mechanisms that provide peace of mind.

Waterproof and Airtight Seals

To protect your ammunition from moisture and humidity, choose an ammo box with a waterproof and airtight seal. This ensures that your rounds remain dry and free from corrosion, preserving their reliability and performance.

Portability

Consider the portability of the ammo box, especially if you frequently transport your ammunition. Look for features like comfortable handles, stackability, and compact designs that make it easy to carry and store multiple boxes.

Frequently Asked Questions (FAQs)

1. Is it a good idea to store ammo in the original box?

It is generally recommended to store ammo in its original purchase box to minimize handling and preserve the quality of the rounds. If desired, you can use an airtight container like an ammo can to store the cardboard or paper boxes of ammo.

2. What is the best container to store ammo in?

Ammo boxes or ammo cans are the best containers for storing ammunition. They provide proper storage and are cost-effective options. If you prioritize maximum security, you can also consider using a gun safe or gun cabinet. Additionally, fireproof safes can be used for ammo storage, although they are more expensive than ammo cans.

3. How long does ammo last in box?

Ammunition generally does not have an expiration date or go bad if stored correctly. While some manufacturers may indicate an expiration date of ten years past the manufacturer date, this is more for legal reasons. As long as ammo is stored properly, there is no known limit to how long it can be kept.

4. Is it OK to store ammo in cardboard boxes?

Storing ammo in cardboard boxes is not recommended. These boxes do not offer sufficient protection from corrosion and degradation. It is best to use dedicated ammo containers or include silica gel packs to maintain the quality of the ammunition.

5. What is the shelf life of ammunition?

Ammunition generally does not have an expiration date or go bad if stored correctly. While some manufacturers may list an expiration date of ten years past the manufacturer date, this is primarily for legal reasons rather than safety concerns. Properly stored ammunition can be kept for an indefinite period without significant degradation.

6. Does ammo go bad if stored properly?

Ammo does not typically go bad if stored properly. However, certain storage conditions can cause ammo to fail over time. It is important to be mindful of potential issues like corrosion when storing ammunition for an extended period. Proper storage practices can help maintain the quality and reliability of the ammo.
