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

Proper Set Up.
When setting up the accessory, if the original set up with a 1/4 turn bumps the shoulder to for, as far as I can tell there is no way to bring the shoulder back up to the once fired depth. That make that cartridge out of tolerance. I also don’t remember in the video the narrator mentioning that once you have exceeded your desired bump length, how to remove length from the carriage to desired shoulder length. Is their any thing in the manual or the video that address this matter or is it assumed if you order a device to hold such precision that this person should already understand the complexity of manipulating the device.
