Yup. Red/rust colored dust & off odor =NG. If it looks good and has that normal "chemical" smell (at least that's what i'd call it), you're GTG. I still have metal cans of IMR powder that were my fathers from the early 1970's, and the resulting hand loads shoot fine. I think HOW the powder is stored is far more important that how old. I know the 1917 vintage, cordite rounds I bought in the 1980s still go bang in my 303 Enfield. -Tom
