Last month I got my hands on some IMR4198, IMR3031 and IMR4895 from the late eighties for free. When I got it home it also had the reddish brown dust and the interiors of the cans were rusty even though the exteriors looked good as new. I am not a chemist but I am told that those signs indicate that the powder has gone bad. It's breaking down and reacting with the metal of the can.
At the closest gun shop to me, that's about eighty dollars worth of powder, but I dumped it anyway. It is not worth the risk in my opinion.
