All of the instructions I have found for setting up an expander die is just to open the mouth of the neck for bullet seating vs. resizing a bottleneck to a different caliber. I have an RCBS 3-die set. Can someone provide info on setting the die up? How far should I screw the expander down to resize the neck? Thanks.
