I think you would like the Universal powder and I have also had good luck with Accurate #5. Both of these burn clean, the Accurate along with a Berry's 180 grain HP works well in my XDM 3.8 40. I am currently working up a load using the Hodgdon HP-38 and will test it out this weekend. If I read Richard Lee's book right, his $20 powder throw will throw anything from gravel to sand and give you a perfect measure every time
. I'm looking and if I can pick one up cheap i'd like to give the Lee a try, but I can tell you that the Unique does not meter well through the Hornady powder throw.
