Ammunition should be stored in the factory carton or package. The labeling and identification on the original package helps to ensure proper future use. Ammunition should be stored in a locked closet or cabinet in a cool, dry area away from children, and away from firearms. Obviously, poor storage conditions, such as a humid or corrosive atmosphere, could cause product damage immediately.
The shelf life of properly stored ammunition is approximately 10 years.
If ammunition is exposed to fire or if ammunition is older than shelf life, contact your local authorities for assistance with proper disposal.
