The Redding Pro Series Die Set (designed for progressive machines) includes the NxGEN carbide sizing die but does not include an expander die because most popular progressive machines expand the case mouth at the powder drop station. A special seating die is supplied with a large entry radius but does not provide bullet crimping ability. This set is also supplied with a specialized bullet crimping die.
Although designed specifically for progressive reloading Pro series die sets also work exceptionally well with single stage presses if an expander die is purchased separately.
