RL550 Priming Issue
I changed over from 9mm to .45ACP this evening. Things were going along great and suddenly I started having problems priming.
I would decap and size, then on the downstroke it would feel as if the primer would set a little hard, and I couldn't advance the case to the next station. So I'd take the case from the powder dump station, and cycle it again, removing the case after it was decapped. This happened about every 10 to 15 cases.
After about the fourth go round I took the tool head off and loosend the shell plate enough to get the case out. The primer was trying to seat sideways. I'm using primarily once-fired Speer and R-P brass. It seemed to be R-R cases that were doing it.
This 550 has a Dillon case feeder and a JW Primer Track Plate, the one with the bearing. Worked fine on 9mm.
I readjusted everything, made sure the primer seating pin and cup were centered and went back to loading. Same problem kept cropping up.
Sometimes I'd 'feel' that the case wasn't aligned for priming and sure enough, when I eased back I could generally push the case it a little deeper into the shell plate. When I'd check the primer slide on these cases the primer was in place, not sideways in the cup.
I thought maybe it was something with the case feed, but the case should be properly located after it has been sized, correct? I've tried loosening and tightening the shell plate, doesn't seem to make a difference.
I'm stumped, any suggestions? At this point I've become pretty adept at moving cases in and out of the powder drop station, and holding the slide on the case feeder to the rear as I clear the occassional sideways primer, but it is slowing me down quite a bit.
Monday I'll call Dillon if nobody can solve my dilemma.

Every Communist must grasp the truth. Political power grows out of the barrel of a gun. Our principle is that the Party commands the gun, and the gun must never be allowed to command the Party Mao Zedong, 6 November, 1938 - speech to the Communist Patry of China's sixth Central Committee
