Works great with a few concerns - RCBS Pro Chucker 7 Progressive Presses

When I have everything adjusted correctly the press works great. When I toss in a little operator error, that's when things can get messy. Press operation requires complete attention to detail without any daydreaming about fun at the range or elsewhere.
My concerns are related to manufacturing errors. The original QCM powder measure was defective due to poor machining and needed to be replaced. I have purchased shell plates for 9mm, 10mm, and .223/5.56. Only the #16 shell plate for 9mm was machined correctly. The #10 shell plate for .223 was replaced twice before I received one that functioned. All that was 9 months ago.
Now I am in the process of obtaining a replacement #27 shell plate. The one I just purchased wasn't machined correctly.
It is frustrating, but RCBS has great customer service. I don't know why there are so many machining errors in their manufacturing processes. It is good the RCBS customer service is so excellent, it's too bad they are getting so much practice dealing with grumpy customers due to defective parts.
