Lee C430-310-RF Load Data?

[Bushrod]

Any good suggestions on Load Data for this 310 gr. cast bullet. I'll be using 7.5" Ruger Superblackhawk at around 950 ft/sec. I have on hand Unique, W-231, Bullseye. Thanks in advance for your help, Bushrod

I loaded many of these in the "long" crimp groove over 18 grains of slow WC-820, (could be H110 or 296 as well), and they shot very well in both my Redhawks and the DW 744, at about 1,100 fps.

The most accurate load I developed for that boolit used a full case of WC-680 for about 1,000 fps. This is a compressed load which has to be seated and crimped hard in one operation. Unfortunately the supply of WC-680 is pretty much gone.

For 950 fps I'd be looking at 2400.

No experience with the fast powders you list. I have had good results with H110/W296 and surplus WC820.

Start with 17.0 grs of IMR4227 , my 7 1/2" Redhawk loves this load.
