L.E. Wilson Neck Sizing Die Bushing .247" - B-247

This neck sizing die bushing is designed to fit into L.E. Wilson neck dies and sizes the case neck to properly grip the bullet. The .247" bushing is used in the reloading process by measuring loaded round diameter and subtracting .002" to .003" to achieve proper neck tension. Installation requires measuring either the loaded round neck diameter or calculating from wall thickness and bullet diameter.
