I sized 3000 9mm casing this weekend an discovered a problem. I started to notice something didn't fell right ,the claw wasn't working right ,had to many jams. What I discovered was the quide rods[the ones with the 7/16 " nuts on top] where coming loose. I took my press off the bench an looked under the press there was an allen bolt on each rod that was loose. After tightening them down the press worked great again. Hope this info helps someone.
