boltfluter,
I've had one for a few years now. I don't know of any cons. As Boyd Allen explained, it can be removed from the press as well as the die and reinstalled back very close to the original set up by recording some dimensions.
In my case, mine lives around a Kelbly custom 6.5x47L FL die that lives in a dedicated Harrell's press. I load for 4 different rifles chambered for that cartridge that were chambered with 3 different reamers. When I switch from loading for one rifle to another, my die is adjusted in a matter of seconds. Is that quick? I'd say yes. Is it repeatable? Very. Has it saved me a ton of time? Yes sir. Is PMA a great outfit to deal with? Definitely!
There's my opinion from my own firsthand experience with one.
Good luck and also, I'd like you to know that I admire your work a lot, as well.

I realize this thread is old, I bought one of these adjustable die rings today and have a question about it. The instructions specify turning the die away from the ram/shellholder .
I have always tried for a bit of cam over when setting up a sizing die, turning the die out would eliminate this possibility. Is it possible to cam over with this PMA adjuster?
Also, I'll be using it in a Harrells combo press that I also just bought, any concerns camming over on the Harrells press? It seems to have a nice little action there, I'd hate to damage the press.

No matter what method you use for setting your die, if getting the proper bump requires raising the die, your contact with the shell holder will be decreased or eliminated. All the adjuster does is to make adjustments easier to do with great precision and speed, but for me that is enough. If you like splitting hairs and want toggle at every setting, to the thousandth, buy two sets of Redding shell holders and modify one set to give you the in between shell holder heights. AS they come they vary by .002. The problem that I ran into is that one of my dies will not bump a work hardened PPC case with a standard shell holder, so I had to shorten one. All of those in the Redding competition sets are at, or taller than standard.

Your press will cam over if its bumping the shoulder. Die contact is not a necessity unless thats just where it bumps. If it did id be shortening the die because i dont want to be boxed in to a die contact bump
Can anyone recommend what is the easiest way a person could do this themselves and keep it flat and square? Thanks.
You can do it a couple of ways. For small adjustments you can do it by hand using wet and dry abrasive paper on a flat surface, measuring as you go. You wil find that the side with the opening for the case cuts down faster than the opposite side. so you may want to push with the back side forward. The holders are not hard and if you take your time and are careful it is an easy thing to do. For small changes I think that this method would give the best control.
Thank you Boyd.
Boyd Allen answered your question, but before you modify anything, try: (1) Verify that your shell holder is standard, i.e., that its deck height is 0.125 inches; (2) Measure/compare the "bump" (cartridge base to datum (CBTD)) that your die/shell holder/cam over combination yields full length sizing your cases. (When camming over, there should be no gap between the top of the shell holder and the bottom of your sizing die.)
If a sized case is too short CBTD, you're a candidate for Redding Competition Shell Holders (RCSH). In that case, first buy one set and try it. Then if you need to do it, Buy another set of RCSH and modify away.

Can you believe we dont have to melt connectors and polish the ends on fiber anymore? I was floored to see the new ways corning and 3m have devised
