Hornady Custom Grade Series III Features The Hornady Custom Grade Series III 2-Die Set is machined for the 6mm GT cartridge with a .243 inch bullet diameter giving handloaders a dedicated sizing die and bullet seater die matched to this bottleneck rifle round. The Zip Spindle design positively locks to eliminate slippage during adjustment while a series of light threads cut into both the spindle and spindle collet let reloaders make fine incremental changes or quickly zip through larger movements. An elliptical expander smooths brass necks during sizing reducing the runout that can hurt accuracy downrange. The seater die includes an in-line bullet seating system and a built-in crimper for consistent bullet seating depth and crimp across a batch. Every die in the set carries one of the finest internal finishes in the industry a level of polish that reduces friction and case scoring during resizing operations. Smooth lock rings with wrench flats make mounting and adjusting the dies in a press straightforward and easy access die boxes keep the set organized on the bench. Hornady backs these dies with a guarantee that they will never break or wear out under normal use reflecting the craftsmanship behind the Custom Grade line. For reloaders working up loads for the 6mm GT this Series III die set delivers precision and durability in a two-die package.
