32 S&W long, 100 grain 314-640 HP, 2.8 grains Power Pistol shot reasonably well in a S&W 3 inch 32.

I prefer Bullseye or ww-231 for this application but year before last, I bought several pounds of Power Pistol and gave it a go. It is a favorite in 9mm, and 9mm Largo, as well as hotter 45 acp loads. It also does well in 38 special heavier boolit loads (158 grain +).
