Vacuum Sealing Ammunition?
I have read where vacuum sealing ammo can cause damage to the primers and actually unseat the bullets, is this true? I used our Food Saver Sealer to seal some .223 ammo today. I sealed it in the boxes, 2 boxes per bag, the seal got real tight.

N ot a problem at all. If you were to subject the ammo to a quick depressurization, it could cause the bullets and primers to dislodge from the atmospheric pressure inside the cartridges. You are not likely to develop that rapid of a depressurization with a home sealer. In fact, sealing up your ammo and then keeping it in a cool location is probably a very good idea. It will certainly keep the moisture away from it.

It’s not the air one ought to worry about, it’s moisture, temp. and movement. The ammo will last as long as you can keep it dry. People have shot century old ammo with no ill effects. Next is temperature. As long as it’s stable it will be fine as great changes in temp. is what causes moisture to accumulate. And shifting. Shifting can break up the powder. It would be a good idea to move the ammo on occasion but if you keep it from moving that helps.

Lets see, powder, primer, no oxygen….. Do you think it will still shoot? I don’t.
Or do you mean sealing the cartridges in a container after you load them? I would use nitrogen as it will cause no problems at all.

I don’t think so and you sealed them in a box so the only real damage would come to the box. I think damage would only occur when the bullets are individually out of the box.

Consumer grade sealers don’t produce enough vacuum pressure to cause you any problems. Your ammo will be fine.

Residential grade sealers are weak. Don’t worry about it.

If you just keep it dry it will be fine for years. Old ammo cans are nice.
