For reloaders who choose to retain the fire formed dimensions of cases rather than resizing the entire case, neck sizing-only dies fit a definite need. Although they only work the necks of cases, they do eliminate some problems associated with excessive headspace. Neck sizing can also prolong case life. All Forster Sizer Dies are equipped with the exclusive E-Z Out Expander. The floating E-Z Out Expander corrects misalignment of the centre spindle assembly and prevents the case neck from pulling off-centre during the expanding procedure. Shell holder sold separately.
