Primer stops shell plate from rotating

I've had my 550 for a few months and it is working fine with one minor issue. With both the small pistol and large pistol primer hardware if I have some sort of issue that results in me doing something a little out of sequence I may wind up with a primer in the primer cup when I don't have a case sitting there. When this happens the primer sticks up just slightly above the top of the cup but it is just enough that I can not rotate the shell plate or slide a new case into the first postion without pulling the handle a little to raise the shell plate. In normal operation this is no problem as there is no primer in the cup when you put the brass on the press or when you are ready to rotate the shell plate, I was just wondering if this is normal or if I have something that needs adjustment

 

Thanks

RE: Primer stops shell plate from rotating

This is normal. When the machine is operated normally, there is never a primer in the cup when you advance the shellplate. The primer anvil is often at irregular heights on live primers, as a safety precaution. The easiest solution is to pull the handle down slightly when advancing the shellplate if you haven't primed a case. This elevates the shellplate above the primer, so it can be indexed.

This issue is easily resolved by tightening the wing nut on the failsafe rod from the automatic powder system. The force from the spring will raise the shellplate platform above the primer. You may also want to verify that the primer sits down into the seating cup and does not protrude above it. This can be adjusted by loosening the set screw and pushing the primer seating punch down slightly and then tightening the set screw.

This seems to be normal.  Take the primer on the ram and start over with a fresh unprimed shell.
