Nice setup! I've experimented with a lot of warmer .40 loads from a 6" KKM G24 .40 S&W. I've had 165 Sierras and thought I had more load data for them, but most of it is with Gold Dots, which probably won't help much as I'm pretty sure the Sierra 165 is longer than the 165 Gold Dot.

165gr Gold Dot, 10.7gr VV3N38 @ 1.150" : 1392 fps avg 7 fps ES
165gr Gold Dot, 9.0gr 800x @ 1.150": 1365 fps avg 14 fps ES
165gr Gold Dot, 9.0gr Longshot @ 1.130": 1,412 fps avg 23 fps ES
165gr Gold Dot, 9.5gr Longshot @ 1.130" 1,485 fps avg (46 fps ES)(808 ft-lbs)

I did find a 165gr Sierra from a stock Glock 35:
