Re: 1st timer
you are correct the Lee progressice can be used as a single stage. by removing the indexing rod. you then can leave your dies in place and do 1 die or operation at a time. the turn the top plate containing the dies to the next die and do all the shells for the next stage.
As I get Older, I have come to understand why our Founding Fathers chose our countrys motto to be "IN GOD WE TRUST", somehow they knew in the future WE would come to the point that WE COULD NO LONGER TRUST THE ONES WHO RUN IT!
