RCP Fab, you're thinking good. But making all those measurements for really good die setting to make really good ammo requires the use of a gauge to measure case headspace. Either the RCBS Precision Mic or Hornady LNL gauge will do well.
Then you can measure the before and after full length sizing case headspace then adjust you die to set the fired case shoulder back about .002".
Hooligan1, I only remember those two numbers that are important for setting dies. For all those those I forget, I can find them with grade school math using the ones I remember just like everyone else who forgets them but does remember the math. One of 'em's the threads per inch on the die. The other's "1" which the threads per inch is divided into to get thousandths per full turn of the die.
