Alliant BE-86
This is a small flake powder.  Depending on your case volume, you can fit just a tad more into a case than say, Power Pistol. 
This powder is extremely similar performance to Power Pistol except with about ~.5 grains less or so...to give similar velocity and pressure.  Generally.  We see no reason to use Power Pistol at all, when this exists. 
As far as flake powders go, our favorite before this was IMR 4756, but that is discontinued.  So now, BE-86 takes the crown for what we think is the best flake powder for 9 MM.  It can do near 1800 FPS in 65 grain Lehigh loads, and has good performance in the comparable ballpark to anything for all weights up to 147.  It has a good degree of versatility. 
We noticed after shooting, the cases are slightly warmer than many other powders here, with the exception of Titegroup, which also heats up your gun/cases.  This really doesn't matter, but we noticed it.

You want what we think is the best flake powder on the market?  We think it is probably BE-86, give it a try.
So...what about BE-86 and what do some cases look like?

Pretty accurate.  This is with a Springfilend XD(M) with Venom Red Dot @ about 5 yards.  Some loads were well above average accuracy and very good velocity. 

The Lehigh Defense 65 grain Xtreme Defender load there on lower left, notice the larger holes in paper.  It does this even at lower, near 1500 velocity while others don't at same velocity.  I think its because the bullets are made on a CNC machine, and have finer cut edges, versus other bullets that are made in mold, etc.
