9mm Micrometer Die Options - Automated Progressive Compatible

[Sniffer]

I am starting to deck out my new press with dies and as I load multiple different types of 9mm bullets (HP, RN, RNFP) I would like to make any switches as easy as possible.

I have most of the stations figured out already, being automated the dies need to be fairly "forgiving" or be designed in such a way that they can centre the brass (wide funnel type mouth).

1. Case Feed
2. FW Arms decapping die
3. FW Arms Dynamic Hold Down die
4. FW Arms 9mm Carbide Sizing die
5. FW Arms 9mm Expander die
6. Powder drop
7. Powder check
8. Buller drop
9. 9mm seater die with micrometer
10. 9mm bullet crimp die with micrometer

So for 9 & 10 what are good micrometer options that will work with an automated progressive? For the seater and crimp I have found micrometer options from both Redding and Lyman offer:

Looking for recommendations (or indeed issues if there are any). Thanks in advance.

A lot of people will recommend the Redding "competition" die, but because of what it costs and the problems you might encounter, I don't think they're worth buying (search the Brian Enos forum for discussion on the die). My recommendation would be to use calipers with a standard RCBS, Lyman, or Lee die to measure the adjustment knob for a somewhat repeatable OAL setting.

Hmmm, are you referring to the thread where some one had a Redding competition seating die and found that it back off over a long period of time resulting in longer than desired ammo?

If so, I have wondered about this, would the fact that it is easy to adjust with no mechanism to lock mean it would back off over time. There are others in the same thread who did not have any issues despite using the same die in the same way.

I have the Short Action Customs micrometer seating die for my precision guns and the adjustment knob is very stiff / hard to turn. I would be astonished if it backed off / adjusted over time but even so I still spot check on a regular basis.

The issue is inconsistent OAL, to the point where most people remove the internal spring, which in my opinion, defeats some of the purpose of that die.

Like I said, most are going to tell you to get that die, but I guess my personal opinion is that it's stupidly expensive for whatever benefit might be gained by its use. Just my .02, probably not even worth that much.

This is the kind of info I am after.

I don't mind expensive if it is good but it seems that may not be the case with the Redding. I will read up some more on the spring shortcomings but if, like I imagine, the spring is between the top of the die and the bullet seater I can deffo see how that could cause inconsistency.
