Thread: Expander ball coming loose on Hornady precision dies

Leave it loose, you get far less runout in your brass

You also get less runout if you use the expander as a seperate job

Don’t pull it out through the neck after depriming, push the expander down into the brass as a seperate task

Redding expanders are bad for this and the taper is actually the wrong way around and favours the expander being pushed into the brass from the outside in

If your detecting runout in your sized brass that’s two of the largest contributors and fixes….
