Me thinks I may be over-thinking, but -- on the other hand -- really am hoping for some sound advice.
I have Dillon 550b, and maybe an inch or so of Bullseye in the powder measure. I concluded a loading, all with this powder, and I am about to start a new, different caliber, run.
I have an unopened 8 pound container of Bullseye.
HERE'S MY QUERY: SHOULD I:
1/ Just add NEW Bullseye to powder measure? or
2/ Dump out what I have, and just use all from new container? or,
3/ After filling, as in 1/ here above, dump it out and rigorously mix the two?
The powder I have in measure out-dates the new powder by at least a decade, if that makes a dif.
What would you suggest I do? I'd imagine powder lots/years production are different enough I may not assume both to have identical characteristic....
Thanks!
