Sir Ron,
After reviewing the prints and description of the Manson vs. Clymer reamers it’s clear that there would be a difference in the rifle chambers cut with one vs the other. But only in the throat & leade dimensions, not in the case dimensions.
However, the FL sizing die needed would seem to be the same regardless of which chamber the cartridges were fired in. Although loads required for equal MVs would probably be slightly different due to the effect of throat length ane diameter as well as leade angle on chamber pressures, headspace and fired case diameters shouldn’t vary, given equal PSI.
This will probably simplify acquisition of resizing die, if it were cut with a resizing spec reamer based on the original 460G&A reamer dimension.
Do you think these are valid asumptions?
