The L.E. Wilson Steel Neck Sizer Bushing is made of hardened stainless steel and is designed to size case necks with precision in .001” increments.
Bushings feature a .003” taper and can be flipped to achieve a tighter sizing in emergency situations or for fine-tuning.
Compatible exclusively with L.E. Wilson dies and not interchangeable with Forster or RCBS dies; bushing selection is based on cartridge neck diameter or case neck wall thickness calculations.
