Lock-N-Load Die Bushing (2 Count)
by HORNADY RELOADING TOOLS

Lock-N-Load lets you switch from one die to another and begin reloading in seconds. No threading dies in and out or adjusting is necessary. The positive locking action of the bushings holds the dies in rock solid, perfect alignment. You'll want a Lock-N-Load bushing for every die you use.
