Ok guys i have head-spaced with gauges and with a case sized in my dies and then go back with 2 pieces of scotch tape for a no go gauge and i have used actual no-go gauges. I have been thinking about this and if .002 setback is what we are looking for when we resize would it not stand to reason when we set head-space with a case sized in our die that a single piece of scotch tape on the base would set head-space at approx .002 over case length which should let us leave our die setup alone and have .002 shoulder setback every time we reload.
If my math is wrong correct me but it all seems to come to the same conclusion. What are your thoughts guys.
