Well using Longshot with the 10mm and 200 grain bullets, I stop at 9.2 grain @ 1225-1235 fps or 9.4 grains 1245-1255 fps...  The brass can show signs at the 9.4 grain in some firearms...

Thanks Shadow!

That's crazy. My 180gr max is 9.2gr with a armscor FMJ, I'm using a G20 with a Double diamond threaded barrel and carver comp.
  I'm sure I could push it hotter but I'm happy with the results
  Highest I've gone with 200gr was 8.1gr at 1141fps. That was my max pressure cut off by primer inspection... I'm rather conservative I guess.
 

When I say that's crazy I mean it in a good way.

Morning Brassjunkie,
Nothing wrong with being conservative. When I want to shoot the hot stuff, which I do frequently, I breakout some of my Underwood stash. I am finding the longer I load 10's, the more interest I have in hotter hand loads
