I just collected a little data on my goto range load. Thought I'd pass it along

Pistol: Glock 20SF gen 3
Temp. 80* f
Bullet: 165gr plated rnfp x-treme
Primer: Winchester WLP
Powder: WST

Load: 5.7gr.
OAL: 1.250
crimp: none

10 rounds through Chrony

Average - 998fps
High - 1010fps
Low - 981fps
Average Dev. - 5.8fps
Standard Dev. - 4.9fps
Energy - 365ft/lbs

They're nice soft shooters with very little smoke.
WST pressure can spike quickly so work up to hotter loads very slowly. Check your brass for telling signs after each load change.
For me the best part of using WST is that during this shortage crap WST was usually available.
I also found WST to be very enjoyable shooting in my 40 S&W and 45 ACP pistols.

Hope this is helpful for someone.
