d_striker Posted November 6, 2015 Share Posted November 6, 2015 I've loaded approximately 20k rounds on my 650 since getting it earlier in the year. I was previously able to lightly crush seat federal primers by leaning into the handle after seating. This would yield a primer seat depth between .005"-.012" depending on the primer pocket depth on mixed brass. Recently, I've been having issues with primers not getting seated properly. No matter how hard I lean into the handle, the primer won't crush seat and some are even high. It seams like the primer seating "punch" just isn't traveling as high based on the appearance of the seated primer. I've tried cleaning the shell plate and tightening it down as much as possible to where it will still cycle but nothing changed. Does anyone have any ideas?

dillon Posted November 6, 2015 Share Posted November 6, 2015 First, verify that the primer seating punch has not backed out of the underside of the platform. Use a 9/16" open-end wrench. If it is tight, then remove the primer seatng assembly, disassemble it and clean it. Otherwise, I would examine the cases that don't prime properly to see if they have crimped primer pockets. Additionally, some foreign brands of ammo have tighter primer pockets than domestic brands. Link to comment Share on other sites More sharing options...

I'll try what you outlined. Link to comment Share on other sites More sharing options...
FTDMFR Posted November 6, 2015 Share Posted November 6, 2015 That happened with my 650 too. The punch had backed out. Link to comment Share on other sites More sharing options...
d_striker Posted November 7, 2015 Author Share Posted November 7, 2015 Yup. Punch backed out. I just loaded up a couple hundred and the primers are back where I like them to be. Thanks for the help. Link to comment Share on other sites More sharing options...

Tom S. Posted November 9, 2015 Share Posted November 9, 2015 The priming station gets dirty a lot quicker if you don't tumble your brass deprimed. Link to comment Share on other sites More sharing options...
arnettcw1 Posted November 9, 2015 Share Posted November 9, 2015 This happened to me several time too, a little blue loc-tite prevented any future problems. Link to comment Share on other sites More sharing options...
RiggerJJ Posted November 9, 2015 Share Posted November 9, 2015 I would NOT put blue locktite on the primer punch...having to apply heat to that area to remove the primer punch would not be good... Just snug it up and go, check occasionally. jmho jj Link to comment Share on other sites More sharing options...

Red requires heat from my experience Link to comment Share on other sites More sharing options...
RiggerJJ Posted November 9, 2015 Share Posted November 9, 2015 (edited) Regardless of how it breaks free, I would not use loctite on the primer punch. Its simply not needed there. The threaded portion of the punch is steel and it's screwed into aluminum, no need for loctite. All it will take is some homer dumping a gob on the part and it will never come loose.
