L.E. Wilson Neck Sizing Die Bushing .335" - B-335

This neck sizing die bushing is designed to fit into L.E. Wilson neck dies and precisely sizes the case neck to grip the bullet. The .335" bushing is calculated by measuring a loaded round's neck diameter and subtracting .002" to .003", or by calculating wall thickness × 2 plus bullet diameter, then subtracting the same amount. It is an essential component for reloaders seeking consistent neck tension and bullet seating.
