I had been wanting a "food saver" for some time, well today while shopping at Sams Club I purchased one. I had no idea how great they worked. I learned a lesson from a buddy's house fire that anything not sealed even if it looked fine and the boxes were untouched were still ruined. I started tonight vacuum packing some CCI SV I recently got in. You cut the bags to any size you need and then it draws an incredible vacuum and seals whatever you put in there. The bags are really thick and robust (think freezer bag X2)

I decided to do two bricks at a time, under normal conditions this is about a months shooting for me , I was able to repack the sealed ammo back in the original cardboard cases it came in and re-tape it . If you look close the vacuum is so great it actually forces the box to slightly cave in on it's self.... these should be fine for some time to come. This puppy was not cheap, but given sealing up ammo and even occasionally food it was $150 well spent.

Great idea Dwight...I didn't go the route of the food saver...Instead I bought one of the cheapie hand held models that you buy pre-sized bags...quart, half gallon, etc., Only cost about $12 and is battery operated...Bags made for the model are a little high in my opinion but they have come out with some generic bags that are a whole lot cheaper. I use mine to take advantage of the "family size" price discounts on various meats and just divide it up into meal size for Joe and me..We also use it to seal loose bulk ammo into handy amounts and all those non descript 22's laying around to be used for tin cans or steel plate shooting. As we all know brass is going to corrode over time due to moisture and by doing this that problem is completely eliminated. The one good thing about the pre-sized bags we use is that they can be re-sealed....Thanks for bringing the preservation of our ammo to light..For in the ground storage though :rolleyes: I would double seal....Dave

I also have one that you can buy either pre-sized bags or the cut your own size. Just never thought about sealing ammo.

Hmmm...good idea. Right now I have all of mine in the safe (with a dehumidifier), but I don't think that will work very well over time since I open the safe fairly often. I seem to have more trouble with shotgun shells corroding than I do wit other ammo.

AND, the way things are headed these days, you may want to bury your ammo and this looks like it will help if things go in that direction. Get some 4" or bigger PVC pipe, put your sealed up ammo in it, cap and seal it... should be safe for years.

You should still seal it in this before you put it in the ammo box, trust me Jim had some stuff in GI Ammo Boxes that was ruined as well

Vac-packing works well, as will any truly airtight container.
Always place a dessicant into the storage pack to pull moisture away
from the primer, powder and metals. You'd be surprised how much
moisture is found in the cardboard packaging the ammunition is sold in.
I drop a silica gel packet or two into my canisters to deal with hidden moisture.
I like the new silica gel packs that change colors as their level of effectiveness drops.

Just a thought. Does anybody know what effect being in a prolonged vacuum enviroment would have on the powder? Are there any volitiles that could be drawn out? Sure wish I was a chemist at times.

Good question. Hopefully, the ammo is sealed tight enough (around the bullet and primer) that the powder won't BE at reduced pressure and therefore outgassing. These types of vacuum sealers don't really pull all that hard of a vacuum. I would be surprised if they reduce pressure more than a few inches of mercury.

Generally, the way to protect metal parts is to pull a good (< 1 Torr range) vacuum, then back fill with an inert gas such as nitrogen or argon. Repeat that two or three times and you'll be in pretty good shape. Otherwise, it's very hard to get water vapor out; it's the last thing to leave.
Anbody who believes in gun control should be taken out and shot.

If you pull vacuum after a fairly short time, the inside of the bullet casing will be at a vacuum also. They are not sealed that well. The volitiles in powder are only there as carriers from the crystallization step. They are dried as well as they can be on a fast production line. So the makers are trying to remove them even before they are put into our bullets. I would not worry about them at all. The performance is from the solid parts of the powder not the volitiles. As for removal of water, yes it will likely be one of the last to leave. 3 cycle vacuum / purge with Nitrogen is a proven performer and should get the moisture levels down to the very low PPM levels.

The other thing this method does is gives you a quick answer to the question about whether the ammo has had any contamination by air or water. Once the seal is broken, it is obvious from a simple glance at the package that the vacuum is lost. If you check on it monthly, and see a bag not tight with some air in it, a simple replacement can be made. It is very obvious just by looking. This should make our ammo good almost indefinitely. Only thing left to protect against is prolonged heat.

As usual, the good folks here come through. Never though about backfilling with N2. If it is good enough for scopes it's got to be good for ammo. And it is cheap, too. Argon not so much.

The hardest vacuum I worked with was only down to 1 micron, just a fore pump, no vapor pump.

(MICRON? Shows you how old I am. Always though a Torr had something to do with bulls and matadors)

Thanks for such a quick reply.

Good shooting.

Had to run to the pet store to pick up a bag of food for my hounds.
Standing in line at the counter, waiting to pay, noticed a bag of cat litter
on sale. What got my attention was the contents, pure SiO2, silicon dioxide
or as it's also known, silica gel. 4 lbs of silica gel for $14. That's enough
to keep about 128 cubic feet of bulk ammo dry, cheaply.

That silica cat litter is what I have used in my tool drawer for about 10 years to keep tools from rusting. Put it in an old piece of stocking. But...if you don't have some sort of reasonably closed container, all it does is draw moisture from the room.
