One thing I learned a long time ago was that running an expander ball dry thru a case neck was not a good plan.
So I got my hands on some Graphite powder and run a brush in it then put some in the neck. Works slick.
Keeps the work hardening of the brass down to a minimum and thats a good thing.
But from what I'm reading here (thanx to all the contributors btw) I'm gonna get me a collet die and give er a whirl.
