Pat Reagin of PMA tools sent a neat item for adjusting dies without shims, or removing the die from the press. It is called a Micro-riser unit and it features two rings threaded together. One ring is locked to the die and has .001" graduations. The other ring can be moved up or down by as little as .0005"....hence "micro". Below is a picture of the unit with my .30 BR Whidden Fl die set up. I put the black mark on the ring to indicate "zero". Good shooting ....James PS- It will also work with a press-type seating die.
