I have an older Square Deal B, and the priming arm no longer picks up a large primer (haven't tried it with small primers) when the press arm is depressed fully. I have to grab the primer arm and give it a tug, and it will pick up a primer every time. I've replaced the plastic tip on the primer magazine, with no improvement.
I called Dillon, and the tech told me that one of the Delrin bushings in the press develops a burr, and that I should remove it with an Xacto knife. I didn't have a burr, but the Delrin was bowed out a bit. I trimmed it, to no effect.
Does anyone have any ideas on what to try next? Dillon offered to rebuild the press for $67. Is it just time to send it back?
Thanks,
-John
