Load Data for Hard Cast Lead Vs Jacketed.
I load lots of Hard Cast lead (Commercial - not home cast) for economy.
Many times Load manuals will give load data for Jacketed bullets of a given weight but NOT Lead.
Where the IS corresponding data for similar weight and style bullets in Jacketed and HCL > it seems to me that the HCL Max and Min Load Data is ~ 3 % below that of the Jacketed.
I DO understand start low and build up, but >>
Is >> Jacketed data minus 3% a reasonable starting point when attempting to extrapolate Jacketed Data to into data for Hard Cast Lead ??
