The L.E. Wilson Steel Neck Sizer Die Bushing .293 is a precision reloading component for handloaders who demand consistent neck tension and concentricity. These hardened stainless steel bushings work with L.E. Wilson neck sizing dies to control how tightly your brass hugs the bullet, a critical factor for accuracy and case longevity. Wilson manufactures bushings in .001" increments, giving you fine-grained control over sizing that you won't find with generic one-size-fits-all approaches.
Neck tension directly affects how well your loaded rounds perform on the range or in the field. Too loose, and bullets can shift in the case; too tight, and you're working the brass excessively and shortening case life. The .293 bushing is marked on its outside to denote its nominal size, which corresponds to the middle of the bore—reamed with a .003" taper to match the typical geometry of a neck sizing die. If you need slightly tighter sizing for hardened brass that's sprung back, or for fine-tuning without dropping to the next smaller bushing size, you can flip the bushing over so the markings face toward the case. That trick gives you an additional squeeze without buying new tooling.
Wilson neck bushings are engineered to comparable standards as Redding bushings and fit L.E. Wilson neck sizing dies. They will not work with Forster or RCBS dies, so confirm your die manufacturer before ordering. Choosing the right bushing size requires a measurement or two: either measure your loaded round's neck OD and subtract .002" to .003" for spring-back allowance, or calculate from case neck wall thickness and bullet diameter. If you're serious about repeatable, book-accurate neck tension, these steel bushings are the foundation.

Frequently Asked Questions
Will this bushing work with my Forster or RCBS neck die?
No. L.E. Wilson neck bushings are not compatible with Forster or RCBS dies. Confirm that you have an L.E. Wilson neck sizing die before purchasing this bushing.
How do I choose the right bushing size for my brass?
Wilson recommends two methods: (1) Measure the outside neck diameter of a loaded cartridge and subtract .002" to .003" to allow for spring-back and correct neck tension. (2) Alternatively, measure your case neck wall thickness, multiply by two, add your bullet diameter, then subtract .002" to .003". Either approach will get you close; you can fine-tune from there.
What does it mean to flip the bushing, and when would I do that?
The bushing is marked on the outside with its nominal size, which refers to the middle of the bore. If you flip it over so the markings face toward the case, the neck will contact a slightly tighter portion of the bore, providing additional squeeze without switching to a smaller bushing. This is useful for hardened brass that has lost tension or when you need fine-tuning between bushing sizes.
Do these bushings come with an L.E. Wilson neck die, or are they sold separately?
These are replacement or additional bushings sold separately. You will need an L.E. Wilson neck sizing die to use them.
