L.E. Wilson Steel Neck Sizer Die Bushing .326 – B-326

Description

The L.E. Wilson Steel Neck Sizer Die Bushing in .326 is one of those small pieces of gear that makes a real difference once you start chasing consistency on the loading bench. It sizes the outside of your case neck to the exact dimension you want, so you can tune neck tension to your brass and bullet combo instead of settling for whatever a standard die hands you. Wilson has been building precision handloading tools for generations, and that attention to finish shows up in how smoothly these bushings do their job.

How the .326 Steel Neck Sizer Bushing Works

This bushing drops straight into a Wilson neck sizing die or a Wilson bushing-type full-length sizing die, and it sizes the neck without a traditional expander ball pulling through on the way out. That approach keeps your brass more concentric and tends to stretch out case life over repeated firings. The .326 marking refers to the diameter at the middle of the bushing, which is where your case neck actually contacts it, so you get precise, predictable sizing every time.

Picking the Right Wilson Neck Sizer Bushing Size

Getting the size right is the whole point. The common method is to measure the outside neck diameter of a loaded round and subtract about .002 to .003 inches, which leaves room for brass spring-back and gives you proper neck tension. You can also measure your neck wall thickness, multiply by two, add your bullet diameter, and subtract that same .002 to .003. Wilson makes bushings in .001 inch increments, so you can fine-tune right down to your exact load.

Built in the U.S.A. for Precision Reloaders

Machined from hardened steel and ground to a clean finish, this bushing is made in the United States and freely interchanges across Wilson bushing-style dies. If you shoot for groups and want repeatable bullet grip from case to case, having a few bushing sizes on hand lets you dial in tension as your brass works and changes over its lifespan.
