cheby Posted May 18, 2020 Share Posted May 18, 2020 I recently got a new 750. Really frustrated with the primer system. Primers are not picked consistently but a single primer test is fine. When I pushed the rod the live primer is flying all over the place. Called Dillon a few times. Replaced the blue tip, checked the alignment, cleaned up everything. Now I ran out of options. What's happening? Link to comment Share on other sites More sharing options...
Nc1911 Posted May 18, 2020 Share Posted May 18, 2020 Check the overall installed height of the primer cup on in the primer bar. I believe it is 1.385” +/- .005 If it is too low the primers will flip out of the cup or if too high be knocked out of the plastic fingers. The manual gives a good picture and text of the procedure.

Nc1911 Posted May 20, 2020 Share Posted May 20, 2020 Cheby, did you get the system to work properly? Link to comment Share on other sites More sharing options...

I have a working theory that it may be related to the overall height of the primer cup on in the primer bar as you mentioned. I actually played with that before and it seemed to be more reliable when the height within the spec. However, it is impossible to keep it at the this height. No matter how much I tighten the screw, after 200 rds or less, it goes back to 1.370. I called Dillon and they told me it should not be a problem at that height.... Thanks Edited May 22, 2020 by cheby Link to comment Share on other sites More sharing options...

Nc1911 Posted May 22, 2020 Share Posted May 22, 2020 (edited) Well if you are going to upgrade go to a Mark 7 so you can run a powder check. The Dillons, 1050 and 1100, just don’t have enough stations. Edited May 22, 2020 by Nc1911 Link to comment Share on other sites More sharing options...
