Hello gents.
Assuming one could store ammo properly, how long can it last? 50 years? 200 years?
And, the same with a gun. Stored properly, in theory, how long can it work properly?
Thanks.
If you put them in a sealed barrel of cosmoline they'll probably last until the sun explodes. Then some distant planet in a far solar system will get free guns in the mysterious cylinders raining from the sky.
3-3.5 years
A gun, if properly maintained, could last until the parts wear out. It could last literally forever if it's just being stored. Anything with wood might need that replaced after a couple hundred years though.
Ammo, I'm less sure about. Assuming it's sealed from the outside environment, and there's no moisture, it might last forever. I'm not sure how chemically stable modern powder is.

So, guns should last a long fricking time if stored properly.
Any more ammo info? 3.5 years- indefinitely?

We're shooting surplus from WW2 just fine.
Anon is an idiot.

I have shot paper shotgun cartridges from 1905 that worked fine
Slight rust doesn't affect them
Age doesn't affect them
Only improper storage in high humidity areas would lead to a short shelf life

My Tokarev is stamped with 1942, my Tokarev ammo with 1953...

This is the longest time period you can think of?
70 years ago when we made guns with an already modern manufacturing process?
To answer OP's question I've shot 7.65 browning from pic related, and i'm pretty much sure that the bullets were as old as the gun.
The cooper casings had traces of green oxydation, some misfired, but all in all it worked pretty well.
I precise that back then I was a huge retard, so I didn't even bothered to inspect the gun or grease it before firing it. Still worked fine.

Define improper storage and high humidity

Considering that's the oldest ammo I've shot, that's as specific as I can get before I start talking out my ass.
There's no reason to believe it wouldn't last forever, but ammo hasn't been around that long yet.

Way to call someone an idiot on the internets tho.
But theorically you're right, I know there's Napoleonic Guard reenactements, and they take much pride to fire their blank salvos with the original muzzleloaders.
Not comparable to modern firearms in action sophistication, but still, rifle is fine.

When stored in cool, dry place and protected form direct sunlight,
most factory-loaded ammunition is assumed to have 10-year shelf-life.
Military ammunition which is designed for long storage, can have 50+
years shelf-life as long as the package remains sealed.
I have noticed, that ammunition which has been in storage for 15-20
years was less accurate than fresh ammunition. When I fired several
shots through ballistic chronograph, I noticed that the old ammunition
had more variance in the muzzle velocity. This might be caused by bad
primers (uneven ignition) or deteriorated powder (uneven burn).
After some testing, I finally dismantled all 10+ year old ammunition,
and re-loaded the cases. Currently I am rotating my ammunition storage
so that there are no old ammunition left.
A few weeks ago, I took my grandson and his friend to shoot clays, just
because I had old batch of 12-gauge shells, and I wanted to make room
for a new batch.

What does the military do to make their ammo last longer?
>>28061705
Berdan-primed ammo in sealed spam cans with silica gel or any other moisture absorbing susbtance inside.
I have shot ammo from 1870 and it still worked so I would say pretty damn long. It was a original 577 snider cartridge. I have also Fired a box of 577 martini from 1890.

This.
My 7.62x54r spam can shit is all sealed up. I might leave a round underwater for a bit as an experiment to see how well it's sealed.

Just today, I went to the range with my brother inlaw's .357 revolver. He gave me a 20 year old box of Black Hills Ammo. all 50 of them worked fine.
keep it dry and it will last

My instructor fired stuff from 1917. One misfire.
how often do we get these threads? once a week?
>>28061705
Seal the primer and bullet. If you look at military ammo you'll typically see red stuff over the primer and around the bullet where it meets the case. Pic is sealed primer vs unsealed primer.
>>28061254
I forgot about that, thanks
>>28061281
I keep my shit in ziplog bags with a silica desiccant. takes moisture out of that equation.
