Hardened stainless steel neck bushing by L.E. Wilson with a .003” taper, allowing for adjustable sizing by flipping the bushing.
Not interchangeable with Forster or RCBS dies, and available in .001” increments for precision reloading.
To select the correct bushing size, subtract .002"-.003" from the loaded cartridge's outside neck diameter or add twice the neck wall thickness to the bullet's diameter and subtract .002"-.003".
