Hardened stainless steel neck bushing designed by L.E. Wilson with a .003” taper for precise neck sizing in .001” increments.
Bushing marked .267" can be flipped for a tighter fit in emergency situations or for fine-tuning when less "squeeze" is needed.
Compatible exclusively with L.E. Wilson dies and not interchangeable with Forster or RCBS dies; selection based on loaded cartridge or case neck wall thickness.
