    Use old smokeless powder?

    I have a few cans of old powder, 2400 still unopened. Is there any reason to not use it? I'm in a very low humidity environment.

    If it's been stored properly use it. It should smell like ether also.

    If it looks and smells ok shoot it. Most powders last longer than you would imagine.
    A couple of months ago, I and some family members shot up over 300 rounds of shotgun shells I loaded somewhere around 1985. They all performed perfectly.

    I have an 8 pound carton of 2400 from 70’s to the early 80’s , said he didn’t remember exactly when he bought it. I have been using it in 44 magnum loads and it has worked fine. I am in a very high humidity and hot area it spent a few decades in his outbuilding no heat and no ac.

    also be cautious with loads as it may be more or less powerfull than modern data says

    Since modern "cleaner burning" 2400 calls for lower powder charges than the old stuff (245 gr cast in 44 mag, dropped from 22 gr to 20 gr for a max load), modern reloading manuals should be safe if the powder hasn't degraded (smells odd).

    Have load data from the same period as the powders and never come close to max loads of anything. Mostly shoot mid to low range cast loads. Shouldn't be a problem, good point to be aware of.

    I'd load it and shoot it. Got powder from Dad that old or older, works fine.

    Is it just me or are those IMR cans all blue? I've never seen Dupont rifle powder that wasn't color coded. And I go quite a ways back.

    Must've been. The thought of using 4064 data with 4198 powder gives me the willies, though!

    OP: Those are awesome looking cans. As others have said, if it smells like ether, it is fine.
