Hardened stainless steel neck bushing from L.E. Wilson is marked with a size that refers to the middle and has a .003” taper for precision sizing.
The bushing can be flipped to achieve tighter sizing in emergency scenarios or for fine-tuning when normal sizing is insufficient.
Compatible exclusively with L.E. Wilson dies and not interchangeable with Forster or RCBS dies; selection of bushing size should be based on specific measurements of cartridge or case neck.
