Description
For as long as we've been reloading we've always hated setting up our full length sizing dies. We've been using shims to help this along for quite a long while now, but have not really been pleased with them. It seems we always misplace them, or can't find the ones we need, or grab the wrong ones, and they always seem to be covered in rust. For as many years as we've been doing this we've always been looking for a better way. After searching off and on for a solution to this nagging problem we finally have a workable solution. The PMA Micro Die Adjuster.
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. We successfully used this tool 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 your “shoulder bump” 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

Finally I can get that perfict setting.
A friend told me about the PMA tool. I thought "naw" I can adjust the die just as well. I was totally mistaken. No more do I have to fight a die or lock ring. I can sneak up on a shoulder bump on every case, every time with this tool. I don't use it on a seating die but I can sure see how It could do the same seating < .005 at a time even.

Great Products
The micro die adjuster is a great product and saves a lot of time in getting the proper head space time after time. No more guessing.

Simple and easy
The threads on the micro die adjuster are finer than the standard 7/8-14 and make it easy to make adjustments of .001 or even .0005. I love this tool.

See my first review currently number 9 on the review list and you will see why I bought more of these die lock rings. They are worth every cent you pay for them.

Why did I wait so long !!
Using this tool is like taking candy from a baby !! After watching the video on PMAs' website I decided to give Micro Die Adjuster a try. I went ahead and ordered two so that I had one for each of the calibers that I shoot. Upon arrival I watched the video again on how to set them up properly and within half an hour both units were up and running. Easy to install, easy to adjust and completely adjustable down to .0005". PMA sure hit it out of the park with this one !!
