Articulated details offer more precise reloading, by offering easier adjustments, better alignment and smoother functioning. With one of the finest internal finishes in the industry, Hornady Custom Grade and Match Grade Dies provide a lifetime of reloading. They’re so well crafted that they’re guaranteed never to break or wear out from normal use. Zip Spindle™ DesignThe Zip Spindle™ design on all full length size dies positively locks to eliminate slippage. A series of light threads cut on both the spindle and spindle collet allows you to make incremental adjustments by turning the spindle or you can easily “zip it” up or down for larger movements. Smooth FinishInternal die profile is precision machined and polished to a smooth finish that delivers reliable functioning without case sticking or excessive friction. Our pistol dies feature a titanium nitride “gold ring” finish that’s harder than carbide and doesn’t require lubrication. The super hard coating is perfect for resizing pistol brass and won’t scratch your cases. Lock Rings with Wrench FlatsThe Hornady Sure-Loc™ lock rings clamp around the entire die applying constant pressure across the threads to hold the ring in place. The locking screw tightens the ring without ever coming into contact with the threads, eliminating possible damage. Elliptical ExpanderSuperior 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 also eliminates the need for a separate expander die for necking-up to the next caliber. Compression WasherThis washer provides the necessary tension to make fine adjustments easier, and keep the die set in place. Retainer RingLocking retainer spring removes in seconds for easy disassembly and cleaning of the die. Titanium Coated Sizing RingNo-Risk Lifetime WarrantyOur Straight Wall Pistol Sizing Dies feature a TiN (Titanium Nitride) coated sizing ring (gold ring). This eliminates case sticking and requires no lubrication. The super hard, smooth coating is used in high-pressure, high-wear tools to reduce abrasion, so it’s perfect for resizing relatively pistol brass, and won’t scratch your cases. Less friction also means less wear on cases, for longer case life. Spindle locks in place with collet lock for positive decap and easy adjustment.
