This won't be exactly what you are looking for, but I have done some chrono work with Hodgdon Clays.

Hodgdon's website starting load for Clays, is 3.7 grs with 230 gr Hornady FMJ, 5" barrel, 670 fps. If you are using 230 gr. lead, starting load is 3.5 grs. 716 fps. OAL 1.20"

I loaded 3.7 Grs with 230 gr Rainier, 5 inch barrel and got an average of 675 fps. Power factor approx. 155. I increased the OAL to 1.23". I was trying to develop an ICORE load using 230 bullets.

I need a PF of 170 for revolver in IPSC/USPSA in Canada. I use 4.6 of TITEGROUP (not Clays),230 gr Rainier, 1.21 OAL and get a power factor of approx.173.
