Luger Chambers VS Modern Chambers

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
