Power Pistol is a good place to start.... 6.0 to 6.5 grains. 6.3 seems to be
the sweet spot.
The other day I tried out the load printed on the Titegroup can, which is 4.8 grains. (according to Hodgdon, this is the max... ) This one generated chronoed velocities in the 1150-1175 range out of my Sig P228. I also ran some through the X-Five, and it liked em... due to the longer barrel, some of them were just creeping over 1200 fps.
None of the above are wuss loads, of course... If there are others at the range, you will get a bit of "What the f**k is that? That's not a 9mm."
You can probably crank down either to make fluff loads. I know a lot of guys are making Titegroup loads in the 4.0-4.5 grain range for 115 gr bullets.
I've also used Win 231 before, going up to 4.5 grains. 231 in 9mm though really isn't cut out for high velocities, but if you want to make fluff loads with it, it works great for that.
