FWIW have usually used Bullseye and Unique for all 38 Spl. loads. 231 ball is also pretty good. Used Speer # 6,7 and 11? manuals and a few others for many years. I Never push Any load to max loads, just not worth the risks. Used 2400 in 357 Mag., 45 Colt and 44 Mag before selling them all. 44 Mag was way more than my hand(s) could take.
