If you're serious about precision rifle reloading, the L.E. Wilson Neck Sizing Die Bushing 266 is built for shooters who demand tight, repeatable neck tension. This hardened stainless steel bushing works with L.E. Wilson neck sizing dies to control exactly how much the case neck grips your bullet—critical for consistent accuracy, especially at distance. Whether you're working up handloads for a match rifle or fine-tuning a hunting round, the right bushing diameter makes the difference between acceptable groups and outstanding ones.
L.E. Wilson manufactures their bushings in .001\" increments, giving you granular control over neck fit. The marked diameter refers to the bushing's middle section, which is reamed with a .003\" taper. Because the case neck contacts only the middle portion of the bushing, you can flip it over—markings facing toward the case—to achieve slightly tighter sizing when brass has work-hardened and lost tension, or for fine-tuning the squeeze without dropping to the next smaller bushing. It's a practical option when you need a half-step adjustment.
This bushing is made to specs comparable to Redding neck bushings, but it's sized specifically for L.E. Wilson dies and will not work with Forster or RCBS equipment. If you're stepping into precision reloading or upgrading from generic sizing dies, confirm your die brand before purchasing. Selecting the right bushing is straightforward: measure your loaded cartridge's outside neck diameter and subtract .002" to .003" to allow for brass spring-back, or measure case neck wall thickness, double it, add your bullet diameter, and subtract .002" to .003". Either method gives you the bushing size that delivers the neck tension your loads demand.
