Here's a link to something that'll make adjusting dies very precicely:
Yes, Mr. Guffey, there is a conversion for fractional adjustments converted to thousandths. Multiply the fraction of die rotation by 1/14 and the answer's exact. 1/4 x 1/14 = 0.0178571428571429". .018" for 1/4 turn of the die is close enough for reloaders' use. 1/7th of a turn moves the die 0.0102040816326531"; .010" for all practical reloading use.
