I only tried two powders in mine and found a load I really liked. Win supreme 780 gave great velocity however SD was a little wild. Magpro wound up producing 2960 fps from a 24" bbl with excellent accuracy and was very consistant across the chronograph as well. Might be worth a try if you have some magpro lying around, I have been very pleased. Good luck.
Magpro was developed expressly for the WSM case, and I think it's gotta be a natural for the SAUM case.
