The L.E. Wilson Steel Neck Sizer Die Bushing .256 is a precision reloading component built for handloaders who demand control over neck tension and bullet fit. Wilson's hardened stainless steel bushings are manufactured in .001" increments, letting you dial in exactly the amount of neck squeeze your loads need. Whether you're fine-tuning a match-grade rifle load or solving a problem with work-hardened brass, this .256 bushing gives you the adjustability that separates good reloads from great ones.
Unlike one-size-fits-all sizing methods, neck bushings let you match your die to your specific brass and bullet combination. The marked diameter on this bushing represents the middle section, which is reamed with a .003" taper to engage the case neck progressively. For standard sizing, use it as marked; for tighter control (useful when brass has hardened and lost tension), you can flip the bushing and run it upside down with the markings facing the case to gain an extra .001" or so of squeeze. It's a simple trick that can save fired brass and keep precision loads running when other methods fall short.
Wilson bushings are made to specs similar to Redding's respected design and are compatible with Wilson neck-sizer dies. Note: these bushings will not work with Forster or RCBS dies, so verify your die brand before ordering. If you're already running a Wilson die or considering one, this bushing offers the fine-tuning capability serious reloaders expect.

Frequently Asked Questions
What die brand does this bushing work with?
This L.E. Wilson bushing is designed for L.E. Wilson neck-sizer dies only. It will not fit or function with Forster or RCBS dies. Always confirm your die brand before purchasing.
How do I choose the right bushing size for my loads?
You have two methods: (1) Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003" to allow for brass spring-back and proper neck tension. (2) Measure your case neck wall thickness, multiply by two, add your bullet's diameter, then subtract .002" to .003". Either approach gives you the correct sizing for your specific brass and ammunition.
Can I flip this bushing upside down for a tighter fit?
Yes. Running the bushing upside down (markings facing toward the case) reduces the squeeze slightly compared to the next smaller bushing size. This is useful when brass has hardened from repeated firing and has lost tension, or when you need fine-tuning that the standard increments don't quite provide.
What's the difference between Wilson bushings and other neck-sizing methods?
Bushings give you precise, adjustable control over how much squeeze your die applies to the case neck. Unlike standard sizing dies, bushings let you match the exact amount of tension to your specific brass and bullet, improving consistency and allowing you to salvage work-hardened brass that might otherwise be unusable.
