Vacuum packing Ammo

[LuckyGuy]

I am wondering if Vacuum packing ammo is a good or bad idea.

It won't hurt.
It also wont help unless you plan to store your ammo underwater or some other very hostile environment that would otherwise make the ammo oxidize.
Ammo cans are probably the best ammo storage there is.
They are airtight.
The only thing is that in extreme wet environments, they may eventually rust through in like 10-20 years.
The plastic vacuum pack bags would likely degrade faster then the metal cans though.

If you want to hide a gun in the toilet bowl or bury it in a swamp, load it and vacuum pack it.

Thank you ar15barrels, for the comeback.

I like to vacuum seal bullets and/or brass that I sold and will be shipping. It helps to keep them busting out of the box when dropped during shipment.

Ammo cans are definitely the best way. Vacuum sealing at least with food saver bags have a lot of leaks with ammo. I tried it about 15 years ago and all the bags failed within a year.

Would you think the bag materal is of higher quality now?

I place a large vac bag inside my ammo can put the ammo in the bag, vac seal it then close the can.

I don’t really know. We use the same bags to vacuum seal all of our fish. Back then it was probably 1,000 Pounds of fish a year. Never had a problem but with ammo I did.

Perhaps sealing ammo under vacuum puts additional stress on the bag (10 PSI pressure) and combined with mechanical wear (ammo shifting/wearing against the plastic) results in premature failure. Maybe an airtight seal but not removing what air is in there would suffice.

Personally I think it's overkill. As others have stated ammo cans are airtight (or airtight enough) to preserve ammo for decades in a temperature stable environment. I have some 60 year old mil surplus and 35 year old commercial kept in ammo cans that still go bang.

I don’t vacuum seal my ammo but if I was going on a long hunting trip in wet conditions, I might consider sealing a couple of small bags to ensure keeping them clean and dry.

If you're going hunting I'd consider small watertight plastic containers instead. That way you can open and close them multiple times.

Freezer ziplocks would probably work great too.
