mrdon Posted July 1, 2012 Share Posted July 1, 2012 I ran my first 100 consecutive rounds and about 10 of them had slightly high primers. Sitting them on a flat surface they were high in the center.Im using a 650 and making sure to push all the way up and down on the handle.The other thing is after setting OAL at 1.259 it varies from 1.257 to 1.261.I'm thinking thats probably acceptable but is it a normal occurance? Loading Precision 230 Gr.FMJ and used cases. Just trying to work the bugs out.I would really like to be able to run a thousand rounds without worrying about out of spec. issues.I'm new so don't know whats normal or not on this machine.

DerrickJ Posted July 1, 2012 Share Posted July 1, 2012 Are the head stamps of the cases with the high primers the same? My Hornady LNL hates Winchester brass with Winchester small pistol primers (ironic really). Link to comment Share on other sites More sharing options...
Youngeyes Posted July 1, 2012 Share Posted July 1, 2012 (edited) 10% is 10% too many. Check for crimped pockets or anything that would stop a primer from entering fully. Your variations on OAL are fine. Edited July 1, 2012 by Youngeyes Link to comment Share on other sites More sharing options...

Your oal fluctuation is within normal expectations. As for the high primers I have no issues on my 650 in 9mm. The brass may have crimped pockets. See if your high primers are all in the same headstamp brass. If so that rules the press out. Link to comment Share on other sites More sharing options...

Case brands vary and I'm using large primers.Youngeyes I can't see anything unusual about the primer pockets. Guess I'll call Dillon tomorrow. Going to order some new brass soon and see if there is an improvement. Link to comment Share on other sites More sharing options...
DerrickJ Posted July 1, 2012 Share Posted July 1, 2012 FWIW, my Starline brass seats the primers the best, just a nice positive feel when they seat. The Winchesters seem to be a bit tight. For me only the Winchesters give me issues though, just tighter pockets IMO. Link to comment Share on other sites More sharing options...
RNshooter Posted July 1, 2012 Share Posted July 1, 2012 I might be way off here, but check for a crack in the link arm. Just had to replace one on SDB. HIgh primers was the first symptom prior to it breaking completely. Link to comment Share on other sites More sharing options...

mlmiller1 Posted July 2, 2012 Share Posted July 2, 2012 For the primers, be sure shell plate is adjusted properly. Too loose & primers arent fully seated. MLM Link to comment Share on other sites More sharing options...
mrdon Posted July 2, 2012 Author Share Posted July 2, 2012 I'm starting to think it's operator error.I noticed the handle was jamming up against the cartridge bin.I had the bin pushed too far to the front. Duh. That and trying to pay attention to too many things at once. I did check everything you guys suggested.I'm thinking time and practice will work it out.Thanks for jumping in to help.

PJones1911 Posted November 6, 2012 Share Posted November 6, 2012 I usually double tap the primer seating. I used to get some slightly high primers and realized that when I seat the primers quickly, I think the surface resistance of the primer against the primer pocket binds up a little so when I relax the arm a little and give it another push I get it in much deeper. I find this particularly important when loading for a revolver with a light trigger. Paul Link to comment Share on other sites More sharing options...
