Hodgdon does list data for CFE BLK in the 357 Max under Pistol Data:
https://hodgdonreloading.com/rldc/?t=2It is too slow burning to reach top velocity before running out of case room in the Max. It lags about 200 fps behind other powders at full capacity. If you can seat longer it may help.
My opinion, AA1680 is the best choice for the Max if you want top velocity and good accuracy.
CFE BLK is a better powder in the 360 Buckhammer with 200 gr bullets giving top velocity. It has more case capacity than the Max.
