Honestly I wouldnt bother. Its been inconsistent lot to lot. Plus its one of those powders that disappears for a couple years, the you find it, then you cant.
Lots of as good or better powders that seem to always be readily available.
For action pistol, whether 9mm minor or 40 major, Tighgroup does it all other than generate a bit of smoke with moly coated bullets and seems to always be available.
Alliant SPort Pistol seems like a winner as well, but also seems to made of unobtanium.
