Short answer: store ammunition locked and out of reach of children, in a cool, dry place away from heat sources, open flame and solvents, organized and labelled by caliber. Many people keep it separate from firearms. Storage laws and fire-code limits vary, so check the rules where you live.
Control access
The most important rule is that children and unauthorized people cannot get to it. A locked cabinet, safe or lockable case works. Some states and cities have specific storage requirements, especially where children live - check yours.
Choose the right spot
- Inside the living space: an interior closet or cabinet with stable temperature.
- Away from furnaces, water heaters, fireplaces and anything with an open flame.
- Away from solvents, oils and cleaning chemicals.
- Off bare concrete floors, which wick moisture.
What about fire?
Testing by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) has shown that cartridges that are not in a firearm do not fire bullets with dangerous force when heated in a fire - the case ruptures and the pieces travel only a short distance. That is not a reason to store ammo near heat, but it does mean loose ammunition in a fire does not behave like a fired gun. Some local fire codes limit how much ammunition or powder you can keep at home; check yours if you store a lot.
Organize and label
Sorted, labelled ammunition is safer ammunition: it prevents loading the wrong caliber and makes it obvious when something is missing. Fitted cases with a pocket for every round, one caliber per block and the caliber printed on the lid make that easy. See how to label ammo by caliber.
Keep it in good condition
Cool, dry and steady storage keeps ammunition reliable for years. See our guide to long-term ammo storage for temperature, humidity and container advice.

Loose cartridges not in a firearm rupture with little force in a fire, according to industry testing, but ammo should still be kept away from heat.
Where is the best place to store ammo at home?
