Does taper crimp reduce bullet diameter?
Just curious, has anyone done testing to determine whether or not taper crimp reduces the diameter of the cast bullet inside the cartridge case?
My specific question relates to the 45-70 caliber bullets cast from one in twenty foundry lead. I have always used a roll crimp but just acquired a Redding profile crimp die for the 45-70 and wondered if anybody had a considered opinion whether bullets cast from this pretty soft mix would be reduced in size within the case using such a combo taper/roll crimp?
