Casing gets notched

The second station on my 550b puts a notch in a casing in about one out of 50 casings. This is cleaned range brass that does not follow any one brand with the notching. With no change, the machine works fine before and after the notching. Any ideas?

It sounds like your shell plate needs to be tightened. This will keep everything straight for you.

Thanks for the reply. I called Dillon support and they came through. I knew it was something I was missing but sometimes you need an outsider to find the obvious. I switch back and forth between 9 and 45. I put the 45 brass pins in the shell plate for 9mm, allowing the casing to move. Dillon pointed out that this is documented in the back of the 550b manual and I even found my manual. Good job support.
