The L.E. Wilson neck sizing die bushing 287 is a hardened stainless steel bushing designed for reloaders who want precise neck tension control in their handloading process. This bushing works with L.E. Wilson neck sizing dies to achieve consistent case neck diameter sizing, critical for accurate rifle ammunition assembly. The .287\" designation refers to the middle of the bushing, which is reamed with a .003\" taper—a design that gives you flexibility in how you use it depending on your brass condition and sizing needs.

What sets Wilson bushings apart is their .001\" increment sizing, allowing fine-tuned control that's harder to achieve with standard dies alone. If your brass has hardened and lost tension, or if you need to dial in sizing without jumping to the next smaller bushing, you can flip the bushing over (markings facing toward the case) to squeeze slightly tighter. This emergency adjustment can save a batch of brass that's otherwise lost its spring-back, or help you optimize bullet grip without oversizing.

Reloaders choosing Wilson bushings should note that they're built to specs similar to Redding neck bushings but are not compatible with Forster or RCBS dies—confirm your die manufacturer before ordering. Once you've selected your bushing size using either the loaded-cartridge method (measure outside neck diameter and subtract .002\"–.003\") or the case-wall method (double the wall thickness, add bullet diameter, subtract .002\"–.003\"), you'll find the Wilson bushing delivers the repeatable neck tension that separates average ammunition from match-grade loads.
