Ammunition is generally stable when stored correctly, but poor storage can degrade its reliability and, more importantly, create safety risks in the home. Here is what responsible storage looks like.
Keep it cool and dry
Extreme heat and humidity are the two biggest threats to ammunition over time. A stable, moderate-temperature area of the home, away from direct sunlight and moisture, is far better than a hot attic or a damp basement.
Store separately from firearms
Keeping ammunition in a separate locked container from the firearm itself is a widely recommended practice, particularly in homes with children or other household members who are not the licensed owner.
Use a proper container
A dedicated ammunition storage box or a locking cabinet is preferable to loose storage in the original cardboard packaging, which offers no security and limited protection from moisture.
Label and rotate stock
If you keep ammunition for a long period, label boxes with purchase dates and use older stock first. This is simple good practice, not a safety requirement, but it helps you notice anything unusual with age.
Security is not optional
Whatever storage method you choose, it must prevent access by children or anyone not authorised to handle it. This is both a safety responsibility and, in many jurisdictions, a legal one.
