Does ammo expire?

Ammunition doesn't “expire” per se, but the gunpowder looses potency over time. The largest risk to shooting old ammunition isn't a failure to fire, it's the risk that you will actually fire the shot and it doesn't have enough momentum to make it out the barrel.

Is 10 year old ammo still good?

Generally, yes. If factory centerfire cartridges are stored in a dry, cool place with low humidity, preferably in an airtight container, they can have an amazingly long shelf life. Many ballistics experts who have shot tens of thousands of rounds over the years report shooting 20- to 50-year-old ammo with no problems.

How long can you keep ammunition before it goes bad?

What is this? It's safe to store ammo for ten years or less, as a general rule of thumb. Ammunition that's stored for more extended periods of time runs the risk of going bad, particularly if it's exposed to humidity, high temperatures, or other conditions that could damage its quality.

How much ammo should I stockpile?

A good rule of thumb is to consider a 500-round stash your starting point for your handgun. That might seem high but it does go fast. Of those 500 rounds at least 150 should be defensive, not target rounds. If you can afford to stash mostly defensive ammo, do it.

Can ammunition go off in a fire?

Basically, the heat of a fire can cause a round to fire just as it would if someone had pulled the trigger on a live round. The bullets sitting in the non-aligned chambers can also discharge from the heat.

What happens when ammo goes bad?

The primer doesn't ignite the powder. This is probably the most common side effect of old ammunition. Explosive crystals magnify the explosive power of the ammo. Explosive crystals form through a chemical process, making the ammo more potent, damaging the firearm when fired.
