I've read a few places that Alliant Power Pistol is/was used in an awful lot of factory ammo.
I love the stuff for 9mm, and have looked thru a lot of the pulldown information here for most calibers, and it looks like other similar burning rate powders are used instead (WSF, Silhouette, Longshot etc.) of PP.
I know a lot of powders may physically look like canister grade powders and be totally different but I don't think I saw any educated guesses that PP was in any factory loads.
Just curious if other similar powders are now favored for some reason, or maybe it's all BS.
Power Pistol is a great powder in the 10mm it may not provide the absolute fastest velocities but is is a good balance of performance vs. the economic powder by weight ratio. Also the NEW Alliant BE-86 is ranking right up there too when pushed.
Both make good numbers performance wise.
