Sewwhat89, Back off your die and then run your fired cases into your chamber. Bolt will close hard. Keep screwing down your die in small quarter turns, you'll feel the die moving the case. Keep chambering, until the bolt closes with just a slight pressure. If you keep going your bolt will close easy because you have no pressure left on the brass case. Redding makes a set of shell holders that are .001 steps. Using these shell holders lets you run down your die to contact the shell holder each time, but the thickness of the shellholder keeps from moving the shoulder too far back. If you only load one caliber on one press, you can just lock down the die and you should be OK. Good luck. /ubbthreads/images/graemlins/smile.gif

The stoney point headspace gauge kit from sinclairs makes it cake to check headspace (shoulder bump)
then get yourself a set of redding comp shellholders -- they are 0.002" increments, not 0.001"
you set the die to cam of the +0.010 shellholder then swap shellholders till you get the desired bump.
