[QUOTE="clownbuster, post: 1634236, member: 22486"] Great question Dirtdevil. Correct, ditch the expander ball. My typical setup for controlling my TIR (Total Indicated Runout): -Anneal -A Forster FL sizing die honed to size neck .004" under final sized neck diameter with the expander ball removed[B].[/B] -Set neck tension running cases thru a TiN [B][U]Turning[/U][/B] Mandrel (21st Century) for a final neck diameter of .002" neck tension. Runout hangs in the 0.0005"-0.0015" TIR range, which means actual runout is half that. [/QUOTE]
