The L.E. Wilson 0.284-inch Neck Sizing Bushing is a 0.284-inch neck sizing bushing from L.E. Wilson (brand part no. B-284). The hardened-steel construction holds its size through repeated resizing cycles. Reloaders use interchangeable bushings like this one to size the case neck down just enough for the bullet to seat with the right amount of tension, rather than over-working the brass with a fixed-diameter neck. That control matters most for precision rifle shooters chasing tight, repeatable groups at the range or in competition, where consistent neck tension shows up directly in ammunition consistency.
