For Cast, with RCBS's 35-200 gr FN/GC, I'm using SR4759 or its equivalent from Jeff Bartlett. I call the latter, clone 4759 and have found it just about identical to the original SR4759...loads run 18 to 19 grains with either. I estimate 18.5 will produce 1600 fps from my 22" bbl. I size to 0.360" and cast with WCWW + 50-50 lube.
Best regards and work up to these loads if interested. Rod
