All you people who mention ammo life and referring to WWII or older ammo, that ammo is using Berdan Corrosive primers! That stuff will out live you but modern boxer non-corrosive ammo has a shelf life of about 20-30yrs according to the Army field manual. The chemicals in the two primers is what makes or breaks the life span of ammo…than and how it’s stored.
As for the question, vacuum sealing isn’t going to hurt but the most important thing is making sure the ammo is stored around room temp and dry.
You might create more trouble than what little benefit it would provide. If you have a sealed container that has a vacuum break, then you are increasing the likelihood of moisture being trapped with the ammo. You actually want air circulation to help keep the moisture controlled As long as you have the ammo stored in a dry,cool place,preferably off the floor,you should be fine.
EDIT: Obviously there are stockpiles of stored ammo all over the place-but those are done under controlled conditions. I just hate the idea of someone buying or making a bunch of ammo,sealing it in a "Seal a Meal" and then having the vacuum break,pulling moist air in and not having a sufficient circulation to maintain dryness. Dissimilar metals with an electrolytic pathway will corrode-I’m just use to that from working aircraft airframe repairs,so that is ingrained with me.
Standard brass or steel cased ammo has a shelf life of multiple decades, as long as its kept dry. I would avoid the vacuum sealing, some primers are ‘water sealed’, which also means that it might be possible to break that seal. If a round is very tightly sealed, it could even bulge the case.
If you’re really worried, zip lock baggies/freezer bags would suffice.
Don’t bother ammo keeps a long time e.g. WW2 Browning 9 mm auto souvenir and steel cased lacquered corrosive primed fired 25 rounds and none misfired. The year 1980. Taken by my cousin and brought home in 1945.
I have shotgun shells that are still good that my Grandpa had in his younger days. They have a paper shell. He would have been 103 this year. They were made long before modern technology and they still shoot today.
I don’t see why it would hurt. . The projected life of modern ammo depending good storage is 20-30 years. But I am sure it will last longer if kept right. Of course I never keep ammo around that long so..
uf you keep the bag in good shape l[ike the other answer pointed out about an opening and moisture getting in] then it should really increase it’s storage life as long as still keep in a coll dry place.

If you are going to bury it that will do fine but make sure it is a dry spot………;)
Well it wont hurt… that I know off
Make sure its at least a foot underground so the drug sniffin dogs don’t get to it when the SHTF

Who knows? Shelf life for properly stored ammo is greater than your life time already.
Ammo properly stored doesn;t need anything to prolong its shelf life. I have WW1 surplus ammo that’s been shooting just fine.
