The L.E. Wilson Neck Sizing Die Bushing 311 is a hardened stainless steel neck bushing designed for reloaders who demand precision and control over case neck tension. Built to match the specifications of Redding neck bushings, Wilson's offering gives you a versatile tool for fine-tuning ammunition that chambers properly and shoots consistently—whether you're chasing sub-MOA groups at the range or preparing reliable field ammunition for hunting.
What sets Wilson bushings apart is their engineering and versatility. Manufactured in .001" increments, each bushing is reamed with a .003" taper that allows the case neck to reach only the middle of the bushing. This design opens up a secondary sizing option: flip the bushing over so the markings face the case, and you gain the ability to achieve a slightly tighter fit without stepping down to the next smaller bushing. It's a practical solution when brass has hardened and lost its grip on the bullet, or when you want fine-tuning adjustment beyond what a standard orientation provides.
The 311 bushing integrates into your existing L.E. Wilson neck sizing die setup—just note that these bushings are not compatible with Forster or RCBS dies. Whether you're building precision rifle ammo or maintaining consistent loads across multiple firings, Wilson's straightforward design and quality stainless construction make this a reliable choice for handloaders who value control and repeatability.

Frequently Asked Questions
What size bushing do I need for my cartridge?
Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003". This allows approximately .001" of brass to spring back for correct neck tension. Alternatively, measure your case neck wall thickness, multiply by two, add the diameter of your bullet, and subtract .002" to .003".
Can I use this bushing with my Forster or RCBS die?
No. L.E. Wilson neck bushings are not compatible with Forster or RCBS dies. These bushings are designed for use with L.E. Wilson neck sizing dies only.
How do I get a tighter fit without buying the next smaller bushing?
The 311 bushing can be flipped over so the markings face toward the case (markings facing down). Since the case neck only reaches the middle of the bushing, this reversal allows you to achieve a slightly tighter sizing. This technique is useful when brass has hardened and sprung back more than desired, or for fine-tuning neck tension without stepping to the next smaller bushing size.
Are these bushings the same as Redding bushings?
L.E. Wilson neck bushings are made to similar specifications as Redding neck bushings, though they are L.E. Wilson products and should only be used with L.E. Wilson neck sizing dies.
