Hey Derek,
I have mostly been shooting 124 and 125 bullets, mostly mimicing my IPSC loads..they have worked out pretty well...I'll have to go check my notes and I'll add that later..
Have you checked out Jeff Maass IPSC resource..He has a PDF file with a lot of 38 super loads and most of those could be used for a starting point. As the case thickness is different enough to change the pressure and velocity. I'll get back to ya.
