Shelf life?

I have some I bought 30 years ago that works fine.

I suppose it depends on storage. Mine was locked in a cabinet in a dry garage (in California weather) all that time.
 
a long long time.... under the right conditions. In the mid eighties I found my dads service 45 that had been locked in his trunk since 1944... fired all seven rounds without a hitch! (This was kept indoors in an AC environment). I have rounds from the 70's and 80's (reloads) and have found no significant degradation. Again, NEVER stored outside/garage/etc. I keep all my ammo in the house, dark and as cool as possible.
 
Thanks for the quick responses! Some guy (who was selling ammo) was telling me that the new stuff has some chemicals in it that will render it useless in less than a year......I rolled up my pants legs 'cause it was getting deep! But, I didn't know what was really right! I keep mine in a gun cabinet drawer, climate controlled and dark.......

Thanks again!
 
It's all the preservatives, steroids and hormone enhancers that are used today,...oh wait that's what we eat and feed our children.

Whew, was worried about my ammo for a second!:D

Trust your depth gauge. Some of them really do think we're stupid.

I've heard this story going around and it did in the last shortage as well, though I heard two years in my version. lol.

I guess it starts as has been said with people who just want to sell ammo no matter what, and is perpetrated by people who think it must be true b/c they read it on the internets.

Utter nonsense of course, but you'd be surprised how many people who should know better have told me it's true. It's silly conspiracies like this one that unfairly discredit the conspiracies that I know are true. ;)

I've shot 22 from the late 40s, I think that's the oldest for me. Don't think I'd rely on my grandfather's paper shell shotgun rounds for self defense, but other than that "indefinite" seems a fair description of ammo life. If properly stored of course.
 
I still can shoot .30 carbine ammo made in '51, I have a box from '44 but I'm not using it because the year matches my M1 Carbine not because I don't think it will shoot.
 
The oldest ammo I ever fired was 1911 dated 30.06. 2 of the 3 rounds I tried went off. I waited until 2011 when it was 100 years old to try it.
 
I recently fired some old beat up ammo that I would estimate to be at least 60 years old - - - NO PROBLEMO! A lot probably has to do with how and where the ammo was stored. The new stuff should be good for many years as long as it is stored in a cool & dry place.

Modern ammo no longer uses a lead based primer . This change in the chemistry of the primers is a fairly recent event , and as such, modern ammo has not yet proven itsself as having a long shelf life .
Many "experts' have estimated that the chemisty used in todays primers may in fact break down and fail in less than 10 years, and some say less than 5 .
The change was made for our health , the government said, as prolonged inhalation of lead particles was bad for us .
In much the same way that we were forced to give up analog TV ,
and incandecent light bulbs , we now gave up long lasting lead based primers in our ammo .
I don't know what standards and regulations they have overseas, but I think it is a good idea to stock up on ammo made outside the U.S.
