The L.E. Wilson Neck Sizing Die Bushing .289 is a steel neck sizer intended to fit into Wilson Neck Dies and size the case neck to grip the bullet consistently. It is a focused tool for precision reloading where repeatable neck tension matters. Selection of the correct bushing relies on direct measurement of a loaded round or calculation from neck wall thickness; examples below show both approaches.
To calculate bushing size, measure the diameter of a loaded round at the point where the bullet sits in the neck (example: .268). Subtract .002 to .003 from that measurement to determine the recommended bushing size (example: .268 – .002 = .266 bushing).
Alternatively, measure the case neck wall thickness, multiply by two, add the bullet diameter, then subtract .002 to .003. For example: .012 wall thickness × 2 = .024. Bullet diameter .243 + .024 = .267. Subtract .003 to arrive at a .264 bushing.
