REDDING 9mm Luger Expander Die (93172)

The Redding Expander Die for straight wall cartridge cases is unique in the design of the expander plug itself. Where may such dies simply bell the case mouth, a close examination of the profile of the Redding expander shows the many facets of its design. First is a tapered lead to easily enter the mouth of the case, followed by a parallel section, which expands and trues the internal portion of the case, which will hold the bullet. Next is a slightly larger shoulder to create a "seat" for the bullet to rest in as it is seated and finally there is a taper for flaring the case mouth to ease bullet insertion. All of this extra machining on the Redding Seat Die makes bullet seating very simple and precise with a case has been fully prepared and expanded.
