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

Brilliant Product!
I can keep brass for multiple guns and barrels in perfect bump and return to that adjustment within seconds. Beats the hell out of shims.

Innovative backed with Quality
I fortunately learned of your Micro Die Adjuster, arranged to have a friend add 3 to his order and subsequently purchased 4 more to outfit all my dies with this incredible device.

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.
