Do these dies require the case to be lubed?
Other factors that can improve concentricity:
• Lube case necks, even with TiN coated bushings.
I do not lube when I resize with my bushing dies, but it probably wouldn't hurt to dip the necks in powdered graphite. You might already use it for lubing the inside of case mouths when you resize with an expander ball, if not try it. If you uniform primer pockets, powdered graphite also allows the cutter to work on new brass without chatter.
