The L.E. Wilson Steel Neck Sizer Die Bushing is made of hardened stainless steel and designed in .001” increments for precision sizing.
It features a .003” taper with the ability to reverse the bushing for a tighter fit or fine-tuning when brass has hardened or to adjust neck tension.
These bushings are specific to L.E. Wilson dies and are not interchangeable with Forster or RCBS dies, with sizing selection based on cartridge measurements.
