Blue Dot and Herco work but are dirty. Bullseye and 231 are good powders and meter well. The list goes on but CFE Pistol Powder has become my go-to powder for a wide range of pistol cartridges.

Doubs,
There is a new, "modernized" Herco powder being produced by Alliant (please see their website advertising it).
To what level of cleanness this new powder will shoot in shotguns and pistols (particularly a 9mm Parabellum) is yet to be seen by me.
I weigh all of my powder charges (for both rifle and pistol shooting) with a Lyman Electronic Scale, for precision shooting with both.
With the original formula Herco powder, I haven't noticed a great deal of dirtiness with the 9mm Parabellum; whereas, Unique has always been a filthy burner for me, both in its new and older formulas.
Respectfully,
Sieger
