Alliant lists a std velocity 38 Special using 4.6 grs BE-86 and 158 gr cast at 982 FPS - Alliant confirmed that this was with a universal unvented 6 inch barrel. I suspect actual velocity would be at least 150 FPS slower. Very disappointed with the lack of any viable “real world” revolver reloading data using cast bullets and BE-86 in 38/357...guess I’m out to the range with my chronograph again.
