After I get home tonight, I'll do the following for you.
I'll check one sources database for published data sources.
I'll also run the 9Largo through a internal balistics program, and post up some of the results.
Here is some that I had buried for one reason or another:

Best.
Published data: Speer Reloading Manual # 13, with 115 and 124gr bullet weights. Sierra # 5 is also showing up, but with no mention of what the data consists of (different referance source).
Calculated (I used 17000PSI/CUP for a max pressure, same as the 9 Styer and 38spl +P)
Hornady 115rn fmj OAL at 1.315
VitVin N330 from 6.3 to 6.8gr (highest calculated velocities)
Alliant Power Pistol from 4.6 to 4.9gr
Alliant Unique from 4.5 to 4.8gr
Alliant Bullseye, from 3.7 to 4.0gr (may require filler below 3.9gr)
Alliant Blue Dot, from 6.9 to 7.4gr.
This program uses "green" "yellow (1 in 10,000)" and "red (1 in 100)" to indicate loads that might spike above max input pressure. Everything I gave you is in the green and yellow range, no "reds"
