Using two cases, you can accurately measure shoulder setback. I shoot for 20 thousands. I tuned my die to this and locked it in. However In this video it shows more, as I didn’t zero my calipers properly. I think you’ll still get the tip.
I am using:
a hornady lnl press.
a universal hardened steel decapper die
Lee 300 aac die
Cheap calipers
Fireformed brass
