The L.E. Wilson Steel Neck Sizer Die Bushing .261 is a hardened stainless steel neck bushing designed for handloaders who demand precision and control over brass neck tension. If you're working with a progressive or single-stage press and running L.E. Wilson neck-sizing dies, this .261 bushing gives you the fine-tuning capability to dial in exact bullet grip—especially valuable when you're sorting quality brass, working up loads, or managing the hardening that comes with multiple reloading cycles.
L.E. Wilson bushings are manufactured in .001" increments, and the marked size represents the middle of the bushing's reamed bore, which features a .003" taper. This design means the case neck contacts only the middle portion of the bushing during sizing. That tapering geometry is key: you can flip the bushing over (markings facing the case instead of away) to achieve a slightly tighter sizing action—a useful trick when brass has work-hardened and lost tension, or when you want to fine-tune squeeze between bushing sizes without stepping down to the next standard size. It's an elegant solution for handloaders who understand that neck tension directly affects precision and velocity consistency.
Built to specs comparable to Redding neck bushings, this Wilson bushing will not work with Forster or RCBS die bodies, so verify your press setup before ordering. Whether you're loading match-grade ammunition or hunting rounds, this bushing puts the control in your hands—exactly where it belongs when you're committed to consistent, repeatable loads.

Frequently Asked Questions
Will this bushing work with my Forster or RCBS neck-sizing die?
No. L.E. Wilson neck bushings are not compatible with Forster or RCBS die bodies. Confirm your die manufacturer before ordering.
How do I choose the correct bushing size?
Two methods work: (1) Measure the outside neck diameter of a loaded cartridge and subtract .002" to .003" to allow for brass springback and proper neck tension; or (2) Measure your case neck wall thickness, multiply by two, add your bullet diameter, then subtract .002" to .003". Both approaches account for the springback that creates correct tension.
Can I flip the bushing over to size tighter without buying a smaller one?
Yes. The bushing can be flipped so the markings face toward the case (down). Since the case neck only reaches the middle of the bushing, reversing it provides a slightly tighter sizing action—useful for fine-tuning when brass has hardened or when you want adjustment between standard bushing sizes.
What's the difference between the marked size and actual bushing diameter?
The marked size refers to the middle of the bushing's bore, which is reamed with a .003" taper. The case neck contacts only this middle section during sizing, not the full bushing length.
