Powder Gone Bad????

[musketjon]

I've got a couple of pounds of IMR 4350 that a friend gave to me several years ago. It doesn't smell acidic or have a pungent odor to it but when I pour it out of the cans into another vessel it emits a very fine, rust-colored dust that clings to anything it touches. The inside of the cans show no obvious signs of rusting. Is it still useable or is it a spontaneous-combustion scenario waiting to happen? Is it time to pour it on the lawn or flower garden??
Thanks

Musketjon, did you get an answer to this on any other forum? I would not use it and wonder if I'm being a big sissy.

The general concensus seemed to be to feed it to the lawn or flowers so the lawn got a snack.

Whatever the red dust is, rust, etc., I would imagine that it could possibly change the burn rate of the powder, so I would toss it. That's just a guess on my part, but I wouldn't chance it.

Do not use! The powder has broken down and as pointed out by another poster. The burn rate will be erratic and unsafe. Sorry but safety first we need you to keep posting these challenges!

I have / had two pounds of IMR 4895 (in the old metal cans) both were "unopened" and they too had the fine red dust!



I'm still here :)
