    As long as you keep it from bouncing around and at a reasonable temperature and humidity it should last a life time. I did have some factory ammo (.270) that bounced around in our pickup for about 10 years and when I decided to shoot it so I could use the brass it was much hotter then regular factory ammo. When I pulled the bullets on the rest of the box the powder was kind of crunched up and there for it developed highter then safe pressures. I've got some 1917 .45 ACP ammo here that I would not be afraid to shoot but it's worth more as a collectors item. I've also got several boxes of shotgun ammo (paper cased) that is over 50 years old and it shoots just find.

    In a cool dry place, it should last for many decades. Maybe centuries, who knows? It hasn't been around long enough to test. Scientifically I don't think there's any reason it should "wear out" if properly stored.

    Ammo Age

    A long time ago I shoot a very old ammo, almost greenish, some fire some not. I think 15 to 20 year is the maximun life. For plinking it will be OK, but for defense change the ammo every year.

    There is an old Chinese proverb that says...

    when it comes time to bury your ammo, it is time to use it...

    I would rather stand against the cannons of the wicked than against the prayers of the righteous.

    i don't know exactly how long, but i did read a story this weekend about a civil war collector in Virginia (Any DC Virginians feel free to chime in here or post a link?)who was killed when the artillery shell he was trying to defuse blew up, killing him. So I would err on the side of caution and say that unless you pull the bullets and soak it in water, it can still go off.

    In my own experience, I have some ammo I bought almost 15 years ago that is just fine. I keep it in a safe that has a goldenrod dehumidifier in it and some dessicant backup in case of a power failure.

    Last year I finally fired off a box of Norma brand 9mm luger ammo that I bought in Germany back in 1963. Not a single misfire.

    I am still shooting my reloads from 20 years ago and factory ammo from the 1960s.

    I'm expecting the supply of carry ammo I have been stashing away to be fully functional for the next 20 years. I don't know if I would carry ammo that was much older than 50 years unless I knew that it was stored properly.

    I would stock up on primers cases powder and lead casting equipment,as long as you keep you're powder and primers dry should be good go go past my lifetime,also if you're ammo turns green chances are it wasn't stored in a cool dry place,high humidity = moisture which can effect the shelf life
