n320 for pistol and Varget for rifle. I have loads worked up for every caliber I shoot. Those are the stockpile powders.
However, I like to play with a bunch of other powders to optimize results or process. For example, Varget runs terribly inconsistent through my Dillon. So I save it for the hand measured 223 long-range rifle rounds. But for 223 55g 3-gun hoser rounds, I use 8208xbr through the Dillon. It meters beautifully and performance out to 300 yards is indistinguishable from my 69g Varget loads.
