    Found some unmarked old shotgun powder. I think it is PB. Not like 7625 which is a fine powder black in color. This unknown powder is flakey and a mediun gray color. Looks like International Clays but doesn't have the occasional tan colored flake. Almost positive it is PB as I've loaded only 7625, PB and International Clays in the past.

    Thanks in advance

    PB is not a flake powder PB stands for Porous Ball. When in doubt throw it out!! It's good for gardens.

    Wayne,

    I plan to throw it out. It's only a very small amount. Just curious, don't remember having this stuff so not sure how I came about it???

    So it's not PB. Thanks.

    (how could gun powder benifit a garden?)

    It is either PB or 7625, they are very hard to tell apart. I put 2lbs on my wifes roses and the damn rose bush is as big as a tree

    Cuban is right it's probably PB. If you look at it with a magnifying glass, flake powders are very, very thin. Pb is like a small tube in shape that is cut real small. 7625 is even smaller.

    The nitrocellulose that is in smokeless powder is a fertilizer.

    Don't think it can be PB as PB is similar to 7625-- not a grey flake type. As above good fertilizer. Ross Puls
