I have ascertained the issue is definitely the dies by making use of them in my D1050 Software head, then resizing different 9mm cases like just one stage push. I am only using the press for resizing, and take away the resized cases when the shell plate improvements. That’s ridiculous. https://9mm-bullet-reloading12083.ltfblog.com/35141441/9mm-casing-no-further-a-mystery
