I want to load some very poppy 100gr 357 Sig loads with Power Pistol. I can't find any reload data on this......... anybody ever try it?

I believe Alliant powder at one time showed 10 grs of PP as max for the 115 gr bullet, so I think starting at 8.5 grs would be safe. Work up and watch for case bulging and/or brass ejecting far away.

I've loaded 90's in the sig with unique. It works pretty good, burns clean, etc. Fun to pop cans and jugs filled with water.
