Can you food saver ammo

I use the zip lock type for .22lr. They sit up nice on the bench and you don’t spend an hour cleaning out the floorboard of your truck when you drop a 550 pack. I only use the bags for bulk ammo.
 
I would have to ask is it in case there is a flood ? then Its a smart idea otherwise why just keep in in a constant indoor temp and it should be good for a while many years . Unlike the air in your tires that you should swap out every few months so it stays fresh lol

I’ve seen it done for organization efforts. I bought some 32acp at last gun show that was bulk stuff broke up into 50 round packs for resale. That would be the only purpose I see in doing it. The military is fine with storing crap in ammo cans for decades and not worrying about it.
 
I really don't have an answer to the OP's question, but is anyone in here a chemist? Does gunpowder offgas? Putting things under vacuum can have negative effects. Just try food saving green beans if you don't believe me... they come out mushy and flavorless as can be (turns out you have to blanch them in boiling water first, wife knows now...). I'm just wondering what effect the vacuum may have on the powder, or primers for that matter. It may be something that's fine for bulk ammo, but would effect precision ammo... I just don't know.

As others have said, just use some ammo cans with a gasket (HF sells GI can's for like $13/ea, or smaller plastic gasketed cans for $3 with a coupon. I use both (plastic cans are great for bulk 22, just dump it in and go).

I switched my truck tires to nitrogen filled on my last tire rotation. They charge 10 bucks a tire but it last for a full year.

My guess is that it does off gas. I keep all my ammo in metal GI cans. Every once in a while I'll hear a "pop" from one of the cans. Not super loud, but enough to notice.

If you want to do it for organization have at it. If you plan to store somewhere not climate controlled (i.e. buried) that I'd probably do it in that situation as well. For normal storage in a house/garage/basement I've never had any issues with ammo that's been stored for 30-40 years. If you are worried about flooding, put it in an ammo can or zip lock bags.
 
it would be a nice little science experiment for a boy scout badge...

i bet this must be well documented in military, manufacturer or armament literature.

all ammo starts out from the same lot and conditions etc.

shoot, test, record velocity of ammo to be tested at standard conditions, maybe even a nice little target for keepsakes.

1 box of standard ammo, in the box (no bag or seal or vacuum)
1 box worth of ammo placed in a vacuum sealed bag
1 box worth of ammo placed in a sealed bag..no vacuum
1 box worth of ammo in a standard military ammo can

1 year later....shoot, test, record and compare velocity at the same standard conditions using same rifle.....new target.

That's a great test. I'd be very interested in the results too.
 
My old man bought a cargo container. It was delivered and inside of it was a little over one thousand rounds of surplus 7.62x39. It all shot just fine. No telling how long that stuff been rolling around in there. I cleaned rust off of shotgun shells that I found in a breezeway of an old house. All fired fine. Ammo holds up extremely well.

I took several rounds of several brands of 7.62x39 (commercial and surplus) and submerged under water for two days and every single one of the rounds fired. I have not tried this with any other cartridge though. Match grade stuff probably wouldn't be as watertight.
 
Ammo can with a good seal and throw in a few dessicant packs.

If you are burying it, vacuum seal with a dessicant pack, throw in ammo can with a good seal and then bury it.

Do you have experience doing this, or are you just guessing? Desiccant in a vacuum sealed bag is kind of pointless... there's little to no moisture in there if it's under vacuum. Also, due to the silica being porous, it would create a volume under vacuum, which would accelerate/continue to draw vacuum on the powder more so than not putting in a desiccant pack at all. Gun powder has some sulfur in it, which sublimes naturally, and faster under vacuum... what that does to the powder, I have no idea, but I have a strong feeling it does something (the sulfur is in there for a reason, right?).

If I was going to store ammo in vacuum bags, I'd probably suck 99% of the air out, and seal it without leaving it under vacuum, just to minimize the volume. You get all the benefit, with none of the risk...
 
Foodsaver bags are surprisingly easy to tear. I repackaged a bunch of "Mountain House" meals into food saver bags for a walk-in elk hunt. About 1/2 of the bags were pierced by the dry noodles. They stacked better than the mountain house packaging, which was the point, but I could have accomplished the same with cheaper ziplock baggies.

Just watch your boil time fellas ?

I have heard, but not done this myself, that if you pull a hard enough vacuum that you can change the seating depth of a bullet. I've been good with zip lock bags and ammo cans for most ammo. Some gets put in MTM boxes and cans.
 
Ok I am a dumb ass and did not give you all the facts/ information. I have about (250) 260 rounds loaded up and 350 (338 Lapua) loaded up. I am wanting to place these in long term (20 years plus) area. I was thinking of doing this as it would keep the rounds from being jostled around in an ammo can. Also If I did it in packs of say 40, I could keep an easy round count.
