if stored properly, almost forever. dry and cool environment and sealed it can last a long time. there are people who shoot mil-surp ammo that is 70 years or older that was stored properly that still works great.

Wasn't there some politicians that wanted to make it law that primers had to "degrade" over time so ammo would be bad after like 10 years or something?
Practice doesn't make perfect, it make permanent.

When I hear a Liberal say "I can speak for gun owners because I own a shotgun" I just want to scream "Well I can speak for vegetarians because I like lettuce on my cheeseburger!"

It won't when you get a bit older...lol

I shot a vintage WW I .45 ACP round. It was a hangfire but went bang real good.

Not bad given its age......

I have 100 year old ammo that I would not be afraid to shoot, if it were`nt worth so darn much......I have some 65 year old .303 that I shoot all the time & it shoots great, I have some 7.62x54R made in the late 60`s & it still shoots fine, so I`d say you could store ammo for 30 or 40 years with out any problems if its stored right...............
When all else fails.

We shot lots of old direct fire ammo that had sat in bunkers in Fort Drum from before Vietnam Era, really never had a problem with it at all. Other munitions are a little diff story, I was Anti Armor so every summer, we would go up to drum and last on the 2 weeks list was TOW Live fire with Cement heads. They were Vietnam era, nearly expired and about one out of 6 was a dud! TOW duds are very bad! If they fail to launch, they can do one of 3 things, Nothing at all, delay launch or blow up in the launcher. We were lucky, only saw 1 delay, the rest did nothing at all and EOD removed and blew them downrange (God bless EOD!!!!).

The Department of Defense came up with a fix called a TOW Blanket! it was a flack vest that laid over top of the system to protect the Gunner (Gunners head is within 4" of the encased missile). We never used one but a couple of folks I knew that did said they were very heavy and it made tracking nearly impossible. Leave it to Uncle Sugar to come up with a cure thats nearly as bad as the problem!!!!

And the manufacturers replied "there is nothing that can be done to make a primer go bad in 10 years that won't make it go bad in 10 minutes". Never gonna happen
In life, strive to take the high road....It offers a better field of fire.

Reference primers and ammunition! Yes the Liberal AHs would like to make people think that! Just like every other lie coming from the party on most all subjects. When have they told the truth is the real issue! You know when they are lying its when their mouth is moving. The bottom line as most have advised here. If ammunition is kept dry and in reasonable temperatures there is no telling how long it will last. I certainly do not have any answers because I have some of my Grandpa's ammunition that is over 50+ years old and yes I have fired it and it performed just fine. It has always been kept inside a home in a dry place at a reasonable temperature and when I inherited all Grandpa's guns I inherited some ammunition. Mostly Shotgun and Rifle ammunition. "SO! God only knows!" how long it will last and still perform if properly cared for. He sure took care of it because times were hard even during the depression and ammunition cost a lot of money compared to the income at the time as his weapons did.

Bought some center-fire ammo new in 1973.

Shot the box last year, no duds.

I've shot Russian Milsurp 7.62 x 54R from 1943, it

must have been stored poorly, and the corrosive stuff

seemed to work at the casings from the insides. @3% duds,

with many casings splitting from neck to primer. Given it was

crappy ammo to begin with, poorly stored and 70 years old,

that's not bad.

Never had a problem with anything from the unopened cans,

combloc or not, from any year.

30 to 50 year old 22LR all shoots dependably.
