I have the instructions for the die, but there is no mention of adjustments to counter an issue like this. The instructions seem to cover basic set up and usage.
I was hoping for a voice of experience with this one, in my head, it doesn't make sense to make something smaller and develop issues as though I had made it larger.
Also, die adjustments aside, I would like to know what is happening, not only to fix this issue but to better understand the logic behind the adjustments.
You are only partially sizing the brass. Put the ram in the full up position and screw the die down so it touches the shell holder. Drop the ram and screw the die in a 2 more revs. Now when you size the die will bottom out on the shell holder and you will fully size the case.
The next time you size the cases, back out the die 2 revs from touching the shell holder, and you will then be partially sizing the case.
