Custom-Grade rifle dies begin as specially selected steel that's hand-inspected both before and after it's delivered. The steel is then heat-treated to ensure the durability needed to provide a lifetime of reloading. Then the inside surface of each sizing die is carefully hand-polished to a mirror finish. The result is a die so smooth, guaranteed to never scratch a case. Before assembly, every part of every die is hand-inspected and a protective coating is applied to prevent moisture damage during shipping. The result is the most advanced reloading die set available today. <br /> <br />Elliptical Expander significantly reduces the friction and case-neck stretch associated with other expanders. It threads on so it can't pull loose and eliminates the need for a separate expander die for &quot;necking up&quot; to the next larger caliber. Sliding, In-Line Seating System assures in-line benchrest alignment of every bullet seated. The sliding sleeve vertically pre-aligns the bullet with the case-neck as they enter the die body. As the cartridge is raised, the bullet contacts the floating steel seating stem and is kept in perfect alignment as it's being seated. <br /> <br />Every Custom-Grade New Dimension die set comes in a convenient box which lets you store fully adjusted dies, Lock-N-Load bushings, shell holders and a taper crimp die. Wrench flats located on the die body make adjustments much easier and eliminate damage from adjusting dies with pliers.

Expander spindle improves alignment and enhances accuracy for smoother operation. A solid, one-piece rod guaranteed not to bend or break. Hardened-steel decap pin will not break, bend or crack, even when depriming cases with crimped primer pockets. Elliptical expander significantly reduces friction and case-neck stretch. Threaded and replaceable. Expander die flares the mouth of the case preparing it to receive a bullet. Precision ground and polished.
