Although I don't load any heavy bullets, I use 9mm data - as mentioned above by several Gents - for my .38 SC loads ... with the big caveat that I reduce 9-mil loads by 20% to start off. I have found the Speer 110-g GDHP to be pretty accurate and shoot to point of aim. The round shown used 4.4-g of Universal. I really like the SC's in my snubs because the short cases eject easily and are a breeze to load using HKS speedloaders.
