did you put a mic on the expander? what did it read?
I use Redding National Match die sets on 308, 223 and 220 swift. My first set of Hornady was with 6 ARC. They are working fine for me.
When I have issues I try starting with basics:
Run the press ram completely up, but first back off neck sizer/primer decap several turns or remove it completely, screw size die body down until it touches the shell holder, once it touches back it off 1/4 turn for starters. This amount of back off will vary with the press but is a good place to start. You can always adjust it later for shoulder bump. Next Install a fired and lubed case in shell holder and run it up all the way up into the die stopping at the top of the stroke leaving the case completely in the sizer die and at top of stroke. Next screw the neck sizer all the way down until you feel it touching the the top of the case neck. Next lower the case out of the sizer die, then screw the neck sizer down a few more turns, then run the same case back up and you should be able to feel the resistance of the neck button/expander in contact with the case neck. Continue the above sequence until you can feel the expander exit the bottom of the case neck inside the case.
Let me know if this helps. If you can feel the resistance and extra force needed to move the expander inside the case neck you are there.
