Lee Precision Pacesetter Micrometer Breech Lock 3-Die Set Features The Lee Pacesetter Micrometer Breech Lock 3-Die Set starts with a full length sizing die that returns mixed range .243 Winchester brass to factory specification ensuring reliable chambering regardless of what rifle the brass was originally fired in. The micrometer bullet seating die allows precise repeatable adjustment of seating depth which is critical for reloaders chasing tight groups or matching a specific load recipe. A factory crimp die finishes each round with a firm uniform crimp that improves the pressure curve and reduces velocity variation. Color coded quick change bushings are factory installed on each die so switching between sizing seating and crimping on a Breech Lock press takes only a twist rather than a full die change. This set includes a universal shell holder sized for .243 Winchester along with a powder dipper and printed instructions and load data to help reloaders get started safely. Choosing this die set makes the most sense for shooters running mixed range brass since the full length sizing die resets case dimensions rather than relying on a neck only approach. The Breech Lock quick change bushings save real time at the bench for reloaders who load multiple calibers or switch dies frequently during a session. For .243 Winchester shooters looking for a complete ready to use die setup this kit covers every station needed to turn brass into finished ammunition.
