Vacuum sealing: primers and powder

[akdad]

I have a couple case of Korean War era 30-06 that went thru a flood in late 90s. Out of 300 or so I've shot I've only had one misfire
They were submerged for at least a week or more.

I test fired 6 of the primers in empty cases today and all fired 11 days after being soaking wet. I have the other 6 loaded up to shoot to tomorrow to see if velocity is affected,

How was the second day?

I have primers from 1999 and earlier. I just kept them in a climate controlled area. They still go bang.

The test is on. I ran 12 LR primers under the sink for about 30 seconds, and placed them back in the package. I will test fire one each month and provide feedback.

Got to keep an eye on this

Not saying it won't help if you want to keep them for the next generation, but I have primers from at least the 80's that are in original packages, have always been in climate controlled environments, and they still go bang. I do put them in sealed ammo cans now, but kept them on a shelf out of direct light for years.

I would hazard a guess that the recommendations in Muddyboots attach are widely ignored. No more than 10000 in a residence or retail display...
I keep mine on a shelf in a climate controlled room. After reading the latest Applied Ballistic volume, I added a dehumidifier to the room. I figure it might help with the ammunition and powder in the room as well. My reloading objectives changed from go bang a long time ago to wanting consistency.

How was the second day?

I forgot all about them.

Vacuum sealing powder is especially not a good idea. Vacuum sealing primers is worthless if stored as they are intended to be stored.

for the purpose of this thread, I have primers from 1976, and at last check, they still work.

So 10,000 in house, 10,000 in garage, 10,000 in pole barn, 10,000 in lawn shed, 10,000 in hunting shack. All good!

NFPA is technically a guideline unless codified into law as reference.

Ah oh.... I need to spread out. Come get them

Using primers I bought from a dealer who retired in the late 80's. No issues. Still go bang. No special storage.

I have never vacuum sealed primers. This thread got me interested in dating the primers that I bought marked down to $7.35 back in the eighties. They are Federal 215 primers in a gold box. I bought four bricks and am on the last brick now. according to lot number and packaging they were manufactured between 1963 and 1965. They still shoot every time. They were in the back of my truck when I drove down the Alcan highway in the snow at -50 degrees F. I probably won't vacuum seal my primers. But I might seal the box when it's empty.
