Loading Data & Reloading Procedures / Primer seating problerm
« on: June 04, 2020, 07:55:33 am »
Put the 9mm head back on the Star. Adjusted the seating die. Noticed that the primers were not seating flush with the case and were a few thousands recessed. Loaded 50 as they were and found they worked in a Springfield 1911, but not all worked in a Kahr carry gun. Not even an indication of a light hit on the primer from those that did not work.
Head is mounted correctly, shell plate is installed correctly, as well as primer seat. Machine is over 50 years old, and I have never experienced this problem before in any of the four calibers I reload. Cannot fathom that adjustment of the seating die would be contributing to this problem. What say members?
Plan to dis-assemble and re-assemble the press and head to see if I can determine what the problem might be.
Thought perhaps a slight difference in primer seat height ? I Intend to measure with another before I would consider shortening, but have generally found minimal if any variance in Star parts. Is possible the primer seat could be an aftermarket that came with the 9mm toolhead and be too long? I do not recall this issue the last time I reloaded 9mm (2018 )Maybe will have to get another from RBWillNJ just in case.
Will not have time to do anything before Saturday, so thought I might get some feedback and suggestions.
