I bought an old metal can of IMR 4227 from a friend in a box of powders he doesn't use anymore. So long story short I dumped it in a Tupperware tub to weigh it and it looks and smells fine, except for a fine red dust clinging to side of the tub. So, it's just in the beginning stages of breaking down.
I wouldnt have noticed if I'd run it into my lee powder measure.
What would be the danger if I loaded it and shot it right away? Would it act as normal? Would it kaboom my gun? Would it be weird in pressure?
Thanks for the insite.
Ps, post 52 shows a picture of the powder in question.
