Go bad? I have some powder that's been around for many a year including some in cardboard containers so what do I look for to identify "bad"?
Look into the container and you will see what looks like rust mixed in with the powder. You may also see it along the walls of the container.
Got some of this. Looks like rust mixed with the powder. It will kick up some air born brown dust when poured through the funnel. It's one of my IMR powders I still have but I don't remember which. I have been using Hodgden powders for the past five years. What am I dealing with?
Rug3,
That powder is decomposing. It is no longer safely usable. At some point in the future it can become unstable and dangerous. You should just sprinkle it out into the lawn or garden.
