I’ve chronograhed avg 1,025 FPS using 6.0 grs Power Pistol and 158 gr swc in 6 inch barrel. Ruger B/H with 4 5/8 inch barrel approx. 975 FPS.
Power Pistol is really great for 38 Spl +P 158 gr loadings and I don’t notice any excessive flash with lead/cast bullets.
I’m regulating my Unique supply for mid range 357 Magnum (6.0 grs 158 gr swc, nice and accurate loading) or 38-44 load data from Handloader Oct 2016 using 358156 GC loaded long).
What have been your results using Power Pistol in 158 gr 38 Spl +P loadings?
