I use RL33 and it's fast but not temp stable.

What brass are you using?
Following. Planning on doing some Staball HD load development with my 6.5 RPM, 264 WM, and maybe 6.6-06AI. Will share when available.

I started with PPU 264WM brass but am currently shooting necked down ADG 7 mag brass.
The PPU brass was surprisingly tough and consistent.
Winner, Winner, CHICKEN DINNER!!!
I haven't had time to work up anything on the 264 WMI but I did do a pressure test on the 6.5 SAUM Improved with StaBall HD. I started in the middle of 6.5PRC data and went up from 57 to 66 grains and did not find pressure yet.
This was fireforming brass using Barnes 140 Match Burners. Velocity at 66 grains was 2989fps with a 20" barrel. No pressure signs evident on the brass at 66 grains. Like all ball powders seem to do, I was lethargic on the low end of case fill but started coming alive the higher the case fill percentage got.
It shows some velocity promise at least.
