RE: big mistake what to do
Although I do agree that that can of powder may have been usable it would have been better to discuss it thru a P.M. rather than on this open board!
Case in point, the new reloader asking questions in the same thread; what have we just taught him? Is it really ok to use a contaminated can of powder?
What if someone new to reloading were to be reading this and accidentially mixed his bullseye and H110 in a significant quantity, and recalled reading this thread. They might not grasp the hugh difference in burning rate and could seriously injure themselves.
Guys I don't mean to sound as if I'm lectureing you, just to remind that we don't know who our audience is.
