CryoVac ammo?

[ElBandito]

Hey guys,
I was at work (a restaurant) today cryo-vac'ing some items and the thought came to mind, can i cryovac some loose ammo (ie. lake city) to keep them safe from humidity and the like? Basically for those that dont know, a cryo-vac machine fills a plastic bag with air then removes all the air from the product. Think this will damage the brass or primers?

Not a bad idea if you want to store loose ammo for a period of time, i dont see it doing any harm.

I've heard from a few reliable sources, that the vacuuming process will actually dent the brass in....

hmmm, I doubt it would dent the brass it. If anything, the higher pressure would be on the inside of the case because of the seals, not on the outside where there is vacuum....

yeah i was worried about the issue with denting or caving in the brass. i can adjust the ammount of vacum that the machine creates in the plastic bag but i really dont want a .308 round going off in a $10k machine

There is no point to doing this unless you are going to be in a very wet/marine environment where you will be submerging or wetting the ammunition on regular basis. The reason this is not worth the trouble under normal conditions is because ammunition stores just fine in ammunition cans or other containers for decades and decades. Just look at alot of the mil-surp stuff out there these days from the 1950's. It wasn't "cryo-vaced" and has held up perfectly.

But, if you are going to be tromping around in marshes, swimming, or in a very rough marine environment then sealing the ammo in a vac bag wouldn't be a bad I guess.

Does anyone else remember a topic similar to this about a year ago? A calguns member was showing off his SHTF setup, which I believe was an AR vacuum sealed in plastic
