ammoWhen it comes to storing ammunition for a long period of time, the most common problem you will encounter is corrosion.  Over time, humidity can wreak havoc on your ammo, causing it become unreliable or worse yet dangerous to fire.

If you plan on storing ammunition for an extended period of time, you need to take environmental conditions like humidity into account. Improperly stored ammunition can and will deteriorate over time; in some cases, that could make your stockpile of ammunition dangerous to fire.

Improper storage can cause a whole host of problems. Primers can lose their sensitivity, charges can deteriorate, and cartridges can weaken and even rupture when fired.  You also have to watch out for corrosion problems that can change the size or characteristics of the ammunition, making it dangerous to fire.

Tips for Protecting Your Ammunition Stockpiles

In most cases, the paper boxes that your ammunition came in are probably more than adequate when storing ammo in your house. If you plan on storing it for longer than a couple years, you need to take a couple of precautions.

  1. Vacuum Seal - Vacuum sealing your ammunition can help protect it from water, rust, and even burying it underground.
  2. Rotation – Just like long term food storage, the key to successfully storing ammo is to rotate your ammunition as often as possible. Make sure you mark purchase dates on your ammo cans, so you use the oldest ammo first.
  3. Humidity Kills – Humidity is probably one of the biggest things you need to worry about. Try to keep your ammo in a low humidity location, or use some sort of dehumidifying equipment in your storage area.
  4. Periodic Checks – If you’re not regularly firing your ammo, it’s a good idea to check your supplies at least once every six months for signs of corrosion. Doing periodic checks will make sure your stocks are ready to fire when you need them.
  5. Silica Packets – Those little silica gel packets, that come in just about everything these days, are a great way to keep your ammo in top notch condition. Silica Gel, or desiccant packets, should be placed in your ammo cans to help get rid of moisture.

    take 2 tablespoons of dry uncooked rice and wrap it in a piece of nylon and tie it shut. Drop one in each ammo can and your ammo will stay dry as a bone.

      In your experience, has the rice method worked well? How long have you used it? Thanks for the info.

    I’d like to meet anyone who wants to have a survivors’ group in Florida.
    You can email me your number if you want to get in touch.
    It is killiansredbeer at gmail dot com.
    If you don’t like guns or the idea of being armed, don’t bother me.

    I spray down my ammo with rem oil, I also spray inside the magazine then place my ammo inside the ammo can.

    • Curt says:

      Seems to me that the Rem oil might seep into the cartridge and render it useless . Have you had any problems with that ?

    • Popa Woody says:

      This seems like an incredibly bad idea. Oil WILL seep into cartridges over time. If your intent is to prevent corrosion, oil will work to form a barrier on most metals. Hence oil isn’t a bad plan on firearms themselves, though I prefer a more proactive approach like Zerust. For ammunition, oil is worse than useless. You don’t care os the brass tarnishes. What you care about is deterioration of the primer and the charge. Oil will exascerbate both of those issues.

      The best way to store ammunition long term is to vacuum seal it and use a good desiccant. That’s what the US Military does.

    • Don says:

      Rem Oil is for your weapon, not your ammo. Hate to say it but for long term storage, spraying oil on your ammo can make most, if not all of it useless. Oil will find it’s way into the primers and to the powder, rendering both, unable to perform. I’d suggest using that ammo up asap while it still fires and replacing it with new brass case ammo such as Lake City Arsenal or plain old Winchester in an airtight container with a few dessicant packages. Oil will ruin your ammo. Humidity is your only enemy. Good luck.

    be sure you clean and oil all magazines that you keep loaded every two weeks to keep the springs from being “set”

    Great information! There’s a prettygood networking site over alt-market.com PulpFiction where I am sure you will be able to find a shooter or two.

    I’m looking for a group in the WI area to do a meet and and greet to see if we can start a defense preparedness together. My kids are learning to hunt and use guns and self defense..We all are taking first aide and food preserving. I would like to buy 40ft storage container and turn them into shelters but need the right group of people.

    Something very simple , portable, hidable, has built in molecular sieve and air tight lid for ammo check out bonedryammo.com, no rice or cat litter and you dont recontaminate your stock pile everytime you open a can to get a few rds for a trip to the range.
