The PMA Tool Micro Die Adjuster (MDA) replaces your existing lock ring and can be used with nearly any 7/8-14 full length sizing die. This tool is used successfully with sizing dies from Redding, RCBS, Hornady, Lee, Harrells Precision and those made from Newlon Precision die blanks. It allows you to easily make adjustments to as fine as .0005”. The engraved marks on the MDA are equal to approximately .001” (true adjustment .000992”) of adjustment to the shoulder bump. Splitting the engraved marks is therefore approximately equal to .0005”. The design of the MDA does not allow it to work with the Forster Co-Ax press and is not intended for use with turret presses, progressive presses or the RCBS Summit press. Some custom dies for very short cartridges may require the use of an extended shellholder.Micro Die Adjuster shown in use installed on Custom Newlon/Scott 6mm PPC Die and Harrells Precision Compact Press.

**Includes Thumb Screw Upgrade for locking the adjustment in place
