Long-Term Ammo Storage

It’s a real downer, because let’s face it, ammunition doesn’t come cheap. Because shells that show signs of corrosion have likely been exposed to too much humidity for too long, the ammunition now poses a danger to anyone who chooses to fire it. Storing ammo improperly can cause a host of problems including a loss of sensitivity in the primers, deterioration of charges, weakened cartridges that could crack when discharged. Corrosion isconcerning because it can alter the size of the ammo, which also poses a risk when firing.The way to make sure this unfortunate situation doesn’t put a damper on your hunting season is to take a few extra steps to ensure your ammo will remain safe and reliable to use for the long term. Here are a few tips for achieving this:

Keep away from extreme heat

In most cases ammunition is made to work as it should in all kinds of climates, from a tropical island to the arctic tundra. But add in extremely hot conditions (starting at about 150 degrees Fahrenheit), and you can easily go from having a well-stocked collection of shells to a whole lot of useless ammunition. Experts at the Sporting Arms and Ammunition Manufacturers’ Institute, Inc. say there are relatively few situations in which temperatures will climb to that level, but temperatures can skyrocket easily inside the trunk of a car, or inside a vehicle on a particularly hot day.

In those environments, the chemical properties of priming mixture and gunpowder can be adversely affected. Eventually, the ammo may be so damaged that it may not produce more than a disappointing “click,” let alone the “bang” you expect to hear when shooting.

Seal it up

Oftentimes the original boxes that contain your ammunition when you buy it provide adequate short-term protection if you intend to keep it somewhere inside your home. If you wish to keep it on hand for two years or longer, however, you will need to use some added protection. Vacuum sealing will keep the moisture away, which will prevent rusting.

Date and rotate stock

Consider how you might store food for the long term, and apply those same principles to ammo storage. Always take a moment to mark your ammo boxes or cans with purchase dates, and be sure to use the oldest of your supply first.

The drier, the better

Humidity is one of the main problems people face when selecting the best place to keep their ammunition stockpile. Keep your supply in a low humidity environment if possible, and if you must store your ammo in a relatively moist location, use a dehumidifier to cut down on moisture levels in the air. You could also begin saving those silica gel packets that come with many common items one might purchase at any retail store, such as a pair of new boots. You can add one of these packets to your ammo containers, which will also eliminate moisture.
