    Smokeless and aluminum

    I was wondering if an aluminum canteen (1970s) could be used for storage of smokeless powder?
    Or is there a good reason to avoid it?

    Well I don’t think I’d fill a Metal canteen with powder and screw on the cap nice and tight! Kinda reminds me more of a hand grenade than proper storage for smokeless powder! Lol But that’s just my opinion.

    Yes it could. And if the powder ignites for some strange reason (like in a fire), you have a pressure vessel bomb. Powder cans are made weak so they vent without building pressure.

    I wouldn't. It'd probably be OK, but if there was a problem- it'd be bad, and could have easily been avoided.
    There's too many options to use something plastic, and not (possibly) foul up a good canteen.

    If nothing else was handy- I'd use well cleaned out soda pop or even motor oil bottles, and store them in the dark.
    They're pretty tough, and seal well.

    I've got some powder left over from my .50BMG days that I sealed up in a food vacuum machine bag.
    It's been in the bottom of the shop refrigerator for several years and it's doing fine.

    I’d use it, but that’s just me.

    The canteen is pre 70’s, the plastic version came out in the early 60’s with the nomenclature M-1961. It’s very likely some old aluminum ones were issued in the 70’s, but would have been in training or possibly reserve component units. Having said that, I wouldn’t use it.

    What if I get thirsty out hunting, and only then realize I took the wrong canteen?

    It was just a thought I had when I came across an old canteen. I guess that if it was ok to put nitro cellulose and nitro glycerine in aluminum containers the powder companies would have done it by now?
    I was thinking of chemical reactions degrading the powder- not kabooms from dropping it or static ignition.
    When I said that it was from the 1970's I meant that that was probably the last time it was used as a water container.

    They do use aluminum for cases like Blazer so there shouldn't be a chemical reaction issue.

    So all the powder manufactors that used tin cans before the 1990's were making pipe bombs???
    Get your finger out of your buttom and get real!
    Is there a gas leak in here somewhere?

    Decomposing powder will fume off sulforic acid.
    That'll etch a hole in a powder can. And powder continue to decompose.
    Every veapon in that safe will rust badly!
    Wheres the harm in that.

    But please do enlighten me as to the severe ill effects of degrading powder.
    Oh and please add links to said sites!!!

    Inquisitive minds wants to know?

    The cans that powder comes in is meant to come a part, at the Seem, when the pressure increased! So no powder company’s that sold powder in cans were not selling pipe bombs! If you don’t think it could cause a problem, do your own experimentation and get back to us and let us know how it goes. I know we’re all my fingers are.

    17nut, where is the sulfer coming from that it would decompose into sulphuric acid?

    I stated it in my response. Those powder cans were designed to vent before pressure can build. A canteen is not. Your inquisitive mind should have thought more before you said foolish things.

    Go to the CMP forum and search 'Danger with deteriorating powders'.
    The Enfield forum has info on it as well. So does the SAMMI site.

    Sorry I can't spoon feed the link and info. for you.
    It'll take a litter effort and some reading.

    I would expect nitrous products to be given off. I do not believe there is any sulfur in smokeless powders, but sulfuric acid is used in the manufacture, but it is NO2 and NO3 groups that are in smokeless powders.
    Below are the chemical formulas for nitrocellulose and nitroglycerin; there is no sulfur in the compositions.
    Nitrocellulose
    Chemical formula (C 6H 9(NO 2)O 5) n (mononitrocellulose) (C 6H 8(NO 2) 2O 5) n (dinitrocellulose) (C 6H 7(NO 2) 3O 5) n (trinitrocellulose

    Nitroglycerin | C3H5(NO3)3 or C3H5N3O9 |

    The best way to store powder is in a plastic container that is dark colored and stored in a cool, dark, dry location.
    Might be why commercial powder comes that way.
    Probably just a coincidence.

    I know of IMR-4350 that is in 1lb metal cans. Many powders used to come in metal cans. Even some 8 lb's of W231...

    Plastic and paper canisters are cheaper.

    As has been stated several times, those metal cans are designed to vent at low pressure. A canteen is not.

    In a fire, someone might open the cabinet looking for combustibles and see the canteen and assume it's safe. I would stick to a universal modern designed container first responders might recognize

    And how do we know this? Internet opinion? Sure, they are thin, but still steel, and would likely rupture before building any meaningful pressure. But is this by some big design criteria?

    Or just a matter of keeping costs down?

    A canteen is not.
    A thin, thin, thin aluminum can. It too is certainly not going to hold any kind of pressure.
