3gunken Posted November 15, 2013 Share Posted November 15, 2013 I am loading 45ACP and about 10% of the time the primer does not seat properly . . . I assume it is a setup or adjustment issue but not sure how to fix it Link to comment Share on other sites More sharing options...
Sarge Posted November 16, 2013 Share Posted November 16, 2013 Are you sure there are not small primer 45 cases in your brass? Link to comment Share on other sites More sharing options...

Larry White Posted November 16, 2013 Share Posted November 16, 2013 Make sure the primer punch is screwed in tight and be sure to make a full stroke.----------Larry Link to comment Share on other sites More sharing options...
Sarge Posted November 16, 2013 Share Posted November 16, 2013 Crimped pockets maybe? Any WCC or NT stuff? Link to comment Share on other sites More sharing options...

3gunken Posted November 16, 2013 Author Share Posted November 16, 2013 smashed in with one edge sticking out, or flattened too much Link to comment Share on other sites More sharing options...
Sarge Posted November 16, 2013 Share Posted November 16, 2013 Sounds like crimped brass to me. Or more remote possibility of part of the old primer left in the hole. Link to comment Share on other sites More sharing options...
BMartens Posted November 16, 2013 Share Posted November 16, 2013 Make sure the shellplate is indexing properly. Check to be sure it turns freely and can index like it should. if it is slightly off you will get primers flipped sideways and crushed. Clean, lube and adjust shellplate.

Henny Posted November 16, 2013 Share Posted November 16, 2013 Start with the basics. Make sure your press is solidly mounted to a rock solid bench. With my first 650 I had priming problems until I added additional support. Make sure your station locator tab (PN: 13242) is properly adjusted. It's suppose to be about the thickness of a business card from the casing. Make sure the seater assembly is screwed all the way in. If you have an alignment tool, check to see if the shell plate is properly indexing. Use a smooth consistent stroke when operating the press. If you feel resistance when seating the primer stop and see how the case if out of alignment. I've read (not experienced) that Winchester primers as of late haven't been the best quality. I don't know if this is true or not. I heard it on the internet. Bonjour! Good luck diagnosing your problem! Let us know what you came up with!

cohland Posted November 16, 2013 Share Posted November 16, 2013 (edited) I encountered and solved this problem, also loading .45ACP. In my case, I found some damage to the primer disc, a slight burr had developed on top of the holes, and I believe that was a contributing factor. The solution was to completely dismantle, inspect, and clean the primer system, and replace the disc. Now that I think of it, just turning the primer disc over would have had the same effect. That did it, the problem went away, although I confess that I'm not completely certain about how I did it. Replacing parts always makes me feel better, anyway. If I really understood the primer system better, I would be able to identify the source of what may have been a slight timing problem that caused the damage to the disk. Cleaning the system may have solved the timing problem, if there was one, and I also looked for any wear on other parts that had to do with timing.
