One of my sweet loads is 4.2 gr BE86 using rotor 5 in my Little Dandy on my Tmag w/135 gr RMR Flat nose. I dont own a chronograph but they shoot well, good groups and cycles all of my H&Ks. Solid load. BTW I tried the same powder charge w/124 RMR and not enough oomph to cycle my P30.
 
I have not tried the MW 135gr fp, but I have loaded the Extreme 135gr fp and jhp with BE-86 at a col of around 1.1" 4.9-5.1 gr this powder produced a velocity of around a 1000 fps from a 3" barrel and a 1025 from a 3.3" barrel.
 
I would start with load data for 147s and work up.
You could look at 124 data and 147 data and guess charges some where in the middle will be your MAX, but of course that is guessing....
