These custom-grade pistol dies from Hornady feature the innovative non-slip Zip-Spinlde design, which ensures a precise alignment as well as easy spindle-lock tightening. The internal die profile is precision machined and polished to a smooth finish that delivers reliable functioning without case sticking or excessive friction. The Hornady Sure-Loc rings clamp around the die applying constant pressure across the threads to hold the ring in place. Includes the Hornady exclusive Elliptical Expander to provide smooth neck sizing and significantly reduces friction and case neck stretch. Features a built-in crimper and titanium coasted sizing ring. The ring eliminates case sticking and requires no lubrication.
