    Du Pont Improved Military Rifle Powder No.15

    This one is full pretty full. It smells fine. There is loading data on the back with the bullet weight info missing. I would use it for 30-06 if I knew what weight bullets the powder charge was for. Anyone have that information?

    According to: https://forum.cartridgecollectors.or...wders/15684/10 this powder was introduced in 1914! I believe "IMR" is now the company that took over. Key to finding load data is to find its equivalency.

    I think if you post this question here>>>>http://castboolits.gunloads.com/show...eference/page3

    You'll probably get a concrete answer.

    I have a can of #15 with an intact label. The "proper" charges are:
    150 gr. 50 gr. powder
    180 gr. 47.6 gr.
    150 gr. 54 gr. (2925 fps)
    180 gr. 51.5 gr. (2,700 fps) These velocities are also in the label's charge data

    No problem, I'm impressed with it too, they have all sorts of old literature.
