I have a several pounds of IMR 4320 in the older metal containers.I noticed in one of the containers there is a brown dusty looking material.Am I safe in assuming that this powder is not fit to use?
Pour it out into another bigger container so you can see it. Mine had clumps and discolored pieces. That went into the lawn as fertilizer.
I also learned using it can cause delayed detonation. Not fun.
Post pictures if you can.
