The Pro Series die set, engineered for progressive machines, incorporates the NxGen carbide sizing die (NX-C) but excludes an expander die (EXP), as the majority of popular progressive machines perform case mouth expansion at the powder drop station. It includes a specialized seating die (PRO ST) featuring a large entry radius, though it lacks bullet crimping capability. Additionally, the set is equipped with a dedicated bullet crimping die (CR).
