How long can ammo be stored?
Gunpowder contains volatile chemicals and oxidizers that are held in a stable, granular form, but powder and primers will still degrade over time, especially when subjected to heat and humidity, as noted above. Even properly stored ammunition has been known to corrode through its steel or brass casings as the “off-gassing” of some powders takes place over time. Most high-quality modern ammunition is loaded with non-corrosive powders and primers, and when properly stored, should last decades without meaningful deterioration. However, it’s a good idea to check a sample of your supply once or twice a year to see if there are any indications of moisture, corrosion, or off-gassing.
If you find any of your brass cases exhibit pink staining, pinholes, green “verdigris,” or other corrosion, dispose of that ammo immediately and double-check your storage containers and methods. Don’t use corroded ammo. It’s not worth the risk.
How much ammo can you keep in one storage spot?
Local ordinances may dictate a limit on how many rounds of ammunition may be legally stored in a residence, but in most places in the US, there’s no formal recommendation or limit. However, it’s your responsibility to learn and follow your local laws. There may be different rules within the same state, depending on what city you live in, so make sure you check.
For example, there may be a local law requiring you to keep your firearms and any ammunition securely locked up. There may be a local ordinance limiting the number of rounds of ammo you can legally store in your place of residence. If you rent a home or apartment, you may also be subject to a renter’s agreement that may dictate how and where you must store your firearms and ammunition or may prohibit such items entirely. This also may apply to home/fire insurance policies, so read your documents carefully. Please observe and follow all local laws regarding the manner of storage, and any limits on the amount of ammo you can store. If you don’t like your local laws, work to change them.
Best places to store ammo safely
As we’ve discussed above, the best place to safely store ammunition, as far as preventing damage and deterioration are concerned, is in a cool, temperature-stable, dry place with little or no chance of any contact with flooding or leaks from broken pipes. Ammo should be stored in airtight containers and labeled clearly. Never store ammunition in your vehicle long-term, or anywhere it could be exposed to heat cycling or humidity.
Most people recommend storing firearms and ammunition in separate, secure locations. This is to prevent the possibility of thieves, kids, or other unauthorized people getting access to both your firearms and ammunition. This is a decision that you must make for yourself, but it’s a good idea. Some people keep one safe for their guns, and one for their ammo.
