should i throw away this powder?

[FROGO207]

So the old propellant I found in a paper sack in my grandfathers wood shop up on a shelf a few years ago that turned out to be the same as BALL-C. So I loaded up some 30-06 rounds and it worked for me even though it had to be at least 30 years old by then was no good. Go tell that to the deer I shot with one of those rounds a couple years ago for me will you.
