Hornady Series I Two-Die Rifle Dieset 2 7X57-7Mm Mauser (.284)What makes Hornady dies better?Hornady reloading dies represent the finest in machined craftsmanship. 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.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 from pliers.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.Seater Adjustment ScrewSeater adjustment screw easily adjusts for bullet seating depths.Retainer RingLocking retainer spring removes in seconds for easy disassembly and cleaning of the die.In-line Bullet Seating SystemOur seating system holds the bullet, the case neck and the seating stem in perfect alignment in the sleeve BEFORE the bullet enters the neck of the case. The system includes a floating bullet alignment sleeve, a floating steel seating stem and a built-in crimper for benchrest precision. Bullets are aligned in the sleeve as they enter the die for optimum seating and enhanced accuracy.Built-in CrimperThe built-in crimper gives you the option of crimping without the need for an extra crimp die thus saving a station on your press.Easy Access Die BoxesEvery Hornady die set comes in a convenient box that’s compartmentalized for dies, bushings, shell holders and a taper crimp die. Stackable and clearly labeled, they offer an organized and clean approach to storing your dies.
