Neck Sizing Bushings - Steel Neck Sizer Die Bushing .309

Hardened stainless steel neck bushing from L.E. Wilson. Wilson makes their bushings in .001" increments. The size marked on them refers to the middle of the bushing, which is reamed with a .003" taper. Since the case neck only reaches the middle, a slightly tighter sizing can be achieved by turning the bushing over, with the markings facing toward the case (markings facing down). This is mainly an emergency step to be taken if the brass has hardened, springing back more, and will no longer hold
