I have tried several 10mm powders and bullet combo's myself.
My latest is a 220 gr plated rn out of an 8" cmmg banshee that I had to tame down due to a not fully supported chamber and ripped off casheads. This peaks out at 1,150 fps.
But my heavy load is a 200 grain nosler hp out of a 5" ruger sr1911 at 1260 fps and 1290 fps out of a 5.5" glock 20 and 5.5" alpha wolf barrel.
I use longshot on my stout loads, it performs well, burns clean, and as a pretty linear increase in velocity for each increase in powder. The chambers of my pistols are tight enough that even at those velocities, the case will still fit in a chamber checker (though I only do those loads in new brass, after that they go in the 180 grain 1100 fps plinker bin.
