Bushing Die
A sizing die that accepts interchangeable neck bushings, letting the handloader dial in an exact amount of neck tension on the bullet.
A bushing die replaces the fixed neck portion of a conventional die with a removable ring, or bushing, of a chosen inside diameter. By swapping bushings the handloader sets precisely how far the neck is squeezed down, which controls the neck tension the case holds on the bullet. This puts a tuning variable that ordinary dies leave fixed directly under the reloader’s control.
Bushing dies come in both neck-only and full-length styles, so a shooter can pair precise tension with whichever body sizing the rifle needs. Choosing a bushing means measuring the loaded neck diameter and subtracting the desired interference, which is why these dies pair naturally with neck turning for uniform wall thickness. Compared with standard reloading dies, they trade a little extra setup for repeatable, deliberate tension.
