sasquatch981 Posted December 7, 2019 Share Posted December 7, 2019 So I have a set of Dillon dies for my 650, but want to adjust the depth of the bullet for load development in .308. I want to use a micrometer adjuster and was wondering if anyone has or if you can use this: https://www.amazon.com/Redding-Bullet-Seating-Micrometer-Remington/dp/B00RY9RHC4/ref=sr_1_9?crid=2HK7DBG3GSIG5&dchild=1&keywords=hornady+micro+adjust+seating+stem&qid=1575742387&sprefix=hornady+micr%2Caps%2C226&sr=8-9 I can't seem to find dimensions on dillon dies to see if they use ½-20 threads. And I don't really want to spend $120 on a seating die, when I already have a seating die, I just want more adjustability. Link to comment Share on other sites More sharing options...
OleGreyGhost Posted December 8, 2019 Share Posted December 8, 2019 The Dillon dies are 7/8 x 14nc. They are the same thread size as the RCBS & Lee dies, that I am using. RCBS makes a micrometer seating die that should work & can be found on Amazon for around $ 85.00. Hope this helps..... Link to comment Share on other sites More sharing options...

The Dillon (PISTOL) dies have an internal sleeve that floats, so the interior is smooth - no threads for the Redding or Hornady micrometer head to thread into. EDIT - Actually I am referring to pistol above. The RIFLE Seating die does have threads, but I'm not certain of the thread size/pitch...

Laxman2809 Posted December 8, 2019 Share Posted December 8, 2019 Yeah, I would be surprised if this worked. I think you would have to have had one of these Looking at the site i think it will only work with the redding dies. https://www.redding-reloading.com/online-catalog/126-micrometer-seat-stems-for-standard-dies Link to comment Share on other sites More sharing options...
markcic Posted December 9, 2019 Share Posted December 9, 2019 (edited) The direct answer to you question is no, a Redding insert will not fit in the Dillon die. If you look at page 19 on the Redding catalog the part you referenced in the Amazon link, 9183, fits in a Redding seating die and is not a complete seating die and will not work in the Dillon seating die. You can replace the entire Dillon seating die with a Redding seating die. Dillon sells the Redding micrometer seating die.

RGA Posted December 10, 2019 Share Posted December 10, 2019 (edited) FWIW, I measured the Dillon rifle seating stem and it is .485 inches wide and the pitch is 20tpi Checked with a standard Redding seating stem and it will not fit. It is .556 inches wide. Edited December 10, 2019 by RGA Link to comment Share on other sites More sharing options...
sasquatch981 Posted December 12, 2019 Author Share Posted December 12, 2019 Thanks Guys, I guess I will just go separate seating die, whether that be Redding, Whidden, or Forster. Link to comment Share on other sites More sharing options...
Laxman2809 Posted December 12, 2019 Share Posted December 12, 2019 Redding and Forster are the top 2 IMO for seating dies. Link to comment Share on other sites More sharing options...
jim m Posted December 28, 2019 Share Posted December 28, 2019 Just put the redding mic seating die on my 1050. The redding die is shaving brass, the dillon die did not. Anyone have this issue? Thanks in advance Jim Link to comment Share on other sites More sharing options...
