    You're right - I stand corrected. My concern was that if the air was drawn (I didn't say, "sucked") out of the cartridge, it might result in a less-than-optimum mixture that could keep the round from performing to spec.

    Can you share with us how you've determined this to be true?

    Agreed! Any moron knows that you've got to have an oxidizer to get combustion.

    Brings up an interesting point, though - black powder might actually work in a vacuum, since the oxidizing agent (saltpeter) is solid, and wouldn't be removed by drawing a vacuum on it.

    Send the specs of the pump (vacuum) at sea level. If it is efficient enough to equal about 200,000 feet MSL, well, that is a different discussion. NASA has those chambers, and some commercial companies also.

    Basically, the modern powders in factory stamped ammo have all of the propellent/oxidizer built right into it. The 'extra' air will still be there, even if vacuum packed.

    Now, for all of you brothers who worry about a zero degree at 1,000 meters (Amen) hit, you can argue the finer points.

    Now, pay attention... To use the vacuum packed ammo, you have to remove it from the vacuum to ambient air density = Moot point in this discussion.

    If you want to 'suck your ammo', it is a free country. It will not hurt the ammo.

    Will work fine for ammo, now if you have a few safe queens that you want to preserve just vacuum pack them with some VPI paper and they will last almost indefinitely. No air/moisture = no corrosion.

    Rounds can be fired underwater, no oxygen. You can have hypergolic or other chemical explosions.

    Unless the vacuum is made using something really special it will only drop the pressure by a few PSI.

    I have "heard" that if you vacuum pack garden seeds they will be good for a long (years) time. Something to think about if you are doing long term planing. In the "bunker" vacuum pack seeds of corn, green beans, carrots, watermelon or any garden produce for future need.

    As for ammo, it won't hurt to vacuum pack it.

    Well i am a full time professional firefighter and i can speak from my personal experience that i have never not entered a building due to someone in the front yard saying there’s ammo inside. Or had command pull us out due to info of ammo being inside. i personally store my ammo inside.

    Yes, we know there's no risk of explosion or of getting shot, but it happens every time I hear it on a fire.

    May I suggest residential sprinklers? You will save on your insurance, maybe even get a rebate or tax break or something to help pay for them.
    I completely agree with you that is a command decision and above my pay grade to make that decision. personally i have never been pulled out due to this info but then again i think there is a big difference of someone saying there’s a few hundred or even thousands of rounds in the back room vs. someone saying i have a home based reloading business set up in the back room and i can only tell you how much is in their by the weight. Haven’t ran across that yet personally LOL

    I have a bunch of ammo that I bought vacuum sealed from Cabelas. It's nice to know that long lasting ammo should last even longer and be well protected from the elements.

    We don't vacuum seal the ammo stored in the house, but it is stored in a solid steel, fire resistant safe.

    Even if oxidizers weren't present in the powder's composition, and even if you were able to create a huge enough vacuum to suck out all of the oxygen from the interior of the casings, the second you break that vacuum to access the rounds, atmospheric air/oxygen would immediately fill the void inside the casing again. You can't expect that if you can suck the air OUT of a case, that it would magically become hermetically sealed and not let oxygen back INTO the case once the surrounding vacuum was released. It's not a one-way valve. Air out, air back in.

    The only plausible issue would be if you tried to fire the round while it was still in a oxygen depleted state, and that would only happen in space or in a huge vacuum chamber with you and your gun in there with it.

    Never vacuum sealed ammo, but I have all kinds of vacuum sealed things in my bag.
    One thing I do is vacuum seal clothing sets and have them in my kit.

    To keep my bulk ammo dry, I put it in zip-lock bags with a couple desiccant packs.

    Boxed ammo is stored in watertight boxes, also with desiccant packs.

    If your vac seal has a tube to hook on the tupperware like canisters they work GREAT. You can use them over and over pack in bulk ammo and have piece of mind with storage JIK. The silica pack is extra insurance.
