L.E. Wilson Neck Sizing Die Bushing 285 Diameter Steel

Overview

The L.E. Wilson Neck Sizing Die Bushing in .285 diameter is precision-engineered from hardened stainless steel to provide reloaders with fine-tuned control over case neck tension. Designed to freely interchange in all Wilson bushing-type neck sizing dies, these bushings help ensure optimal bullet retention, consistent seating, and improved accuracy for bench rest and precision loads. To determine the correct bushing size, measure the outside diameter of a loaded cartridge neck with a precision micrometer and subtract .002" to .003" to account for brass spring-back and achieve a consistent .001" to .002" grip on the bullet. Wilson bushings are made in .001" increments, featuring a middle section reamed with a .003" taper. The bushing can also be flipped for slightly tighter sizing, making it an ideal tool for fine-tuning brass necks.
