i have a 1980's cva hawken 54cal and i'm trying to find a good load for (triple 7 fffg & .530 round ball/pillow patch) (the guy i got it from said his load for this rifle was "60gr fffg and .530 rb") the only data i can find is for 2ff powder... Is there a chart for fffg with .530 ball? Any and all help is greatly appreciated...
Thanks,
