fltbed have you tried the Buffalo Bore loading of 11.0 grs Power Pistol listed above?
I loaded this load for Intercooler and myself and duplicated the BB results precisely.

No, I didn't work up that high.

I took a SWAG at a start load of 9.4 gr and worked up to 10 gr, when I had two cases out of five expand a bit more in the web than I'm comfortable with in the G40.  (maybe it's time to invest in a LW barrel) 
The brass fired from the Rock looked fine and I probably could go up more in that gun but it's so much more fun having ammo I can shoot in both with no worries.

I have no regrets as I learned a few things like:
These bullets are a bit undersized so you have to remember to back out the expander die almost all the way.  Otherwise, you won't get enough bullet grip and this is a load you defiantly don't want any setback with.
Longshot sucks with this bullet also.  
Power Pistol is an underrated powder and I should experiment more with it in the 10.

I'll probably revisit this bullet down the road and who knows, I might just get them up to 1400 f.p.s. without having to chuck my brass in the recycling bin afterward.
