Hornady reloading dies represent the finest in machined craftsmanship. Precise machining allows accurate reloading by offering easier adjustments, better alignment and smooth functioning. With one of the finest internal finishes in the industry, Hornady Custom Grade and Match Grade Dies provide a lifetime of reloading. Theyre so well crafted that theyre guaranteed never to break or wear out from normal use. ZIP SPINDLE DESIGN A feature on all full length size dies, the Zip Spindle positively locks to eliminate slippage. A series of light threads cut on both the spindle and spindle collet allows incremental adjustments by turning the spindle or it can easily zip up or down for larger movements. LOCK RINGS WITH WRENCH FLATS The Hornady Sure-Loc lock rings clamp around the entire die applying constant pressure to hold the ring in place. The locking screw tightens the ring without coming into contact with the threads, eliminating possible damage from pliers. SMOOTH FINISH Internal die profile is precision machined and polished to a smooth finish for reliable functioning without case sticking or excessive friction. Most of our pistol dies feature a titanium nitride gold ring finish thats harder than carbide and doesnt require lubrication. The super hard coating is perfect for resizing soft pistol brass and wont scratch cases. ELLIPTICAL EXPANDER Superior to ball expanders, this Hornady exclusive provides extremely smooth neck sizing and significantly reduces friction and case neck stretch. Internal threading prevents it from pulling loose and the elliptical expander eliminates the need for a separate expander die for necking-up to the next caliber.
