Redding Reloading Pro Series Die Set - 9MM Luger. For the most part they are made to our strictest quality standards employing state of the art single-die titanium carbide technology. The three die in a Redding Pro Series consist of a titanium carbide sizing die (with built-in expander) a reloader's expander die and a bullet seating die with built-in crimp. The bullet seating die has an oversized radius allowing a smooth transition from the seating to the crimping dies. Redding Pro Series progressive die sets don't have expander dies because the powder drop station on a progressive reloading machine normally expands the case mouth. A special bullet seating die with rear rim crimp is used. When the case is seated fully into the chamber a second crimping die can be used to crimp the case closed. A decapping rod is not included. However if you don't have a decapping rod one can be purchased separately. Also see the Redding Pro Series (Progressive) Die Set.
