Vacuum Sealing Ammunition

They make air tight ammo cans you can buy now to bury in the ground. I just put mine in zip lock baggies with a desecant and zip bag shut with a straw in one side. Suck out the air and zip it shut the rest of the way from there into a 50 Cal ammo can. Can't say if it works or not because my ammo is only 4 years old.
Are you planning to save this ammo for the future?. Ammo purchased today, sitting on a shelf will out last you in time. You will be gone of old age and that ammo is still going to shoot.
 
I just wondered if vacuum sealing might insure ammunition would not affected by humidity or other outside forces.

I have some .22lr that I would have vacuum sealed and stored.
 
IMO: Vacuum sealing ammo in plastic bags is not worth the effort. For storing ammunition nothing beats Army 20 mm, .50 caliber and .30 caliber ammo cans. For 60 years i have stored my ammo in Army ammo cans. Some is in original factory boxes, some is in belts, much is loose. It's all in ammo cans without dessicant or anything else.

On UXO remediation jobs in Army training areas we found ammo cans that had buried for 30-80 years. Unless the can was rusted through the ammo in those cans was usually in very good condition. In 1994 at Ft. Ord, CA we found one can with a note inside. It was buried in 1917. The .30 caliber ammunition inside was nearly pristine. The ammo was dated 1910.

During Desert Storm the US Army issued .50 caliber ammo made as early as 1943. Stuff had been in cans for 47 years.
 
How does anyone keep ammo long enough do do this?

I shoot as much ammo as I can afford. As much as I try, I can't get a good stockpile.

I've seen surplus just stored in cans last just fine.
 
If you're worried about water or moisture where you keep your ammo, then a johnny homeowner type vacuum sealer is one way to keep the water/moisture out; however, I would never actually put a full VACUUM on the bag before sealing it. On my vacuum sealer, if I push down all the way, it bypasses vacuuming out the air and just gives me a watertight seal on the bag. I've used this method for cell phones/extra cell phone battery to go camping as well as when snail mailing (USPS) things that are sensitive to moisture.

IIRC, all military ammo uses a sealant between the round and case when the rounds are manufactured. Hey, it's our money, the government can afford to use the good stuff, but seriously, when one of our servicemen or servicewomen needs to hear a loud bang, I don't want them to hear just a click.

See my sig line. v
 
I have ammo that has the case corroded. this is from being in my basement for 10+ years. Did I get it wet before I stored it? Was there a leak at some point? This ammo was set on a shelf and semi forgotten about.

So I say keep moisture away from ammo, and keep the temperature moderate (above the dew point) and stable. Cool DRY basement.
