The Hornady Custom Grade Series III 2-Die Set for 6mm ARC gives you the precision reloading dies you need to produce consistent ammunition for this modern intermediate cartridge. Whether you're loading for a new AR platform build or refreshing your 6mm ARC ammo supply, this two-die set includes everything required for full-length sizing and bullet seating—the two essential steps in rifle reloading. Hornady's reputation for quality machining means you get smooth, reliable operation and repeatability that translates directly to tighter groups downrange.
Built to Hornady's exacting standards, these dies feature some of the finest internal finishes in the industry. The full-length sizer and seater are precision-machined to tight tolerances, and the elliptical expander is polished smooth to reduce friction and promote consistent case life. The dies come ready to use in an easy-access die box, so you can organize your reloading bench efficiently and grab what you need without hunting through drawers.
The Series III design includes several user-friendly refinements: the New Zip Spindle makes adjustments faster and smoother, while the Sure-Loc Lock rings feature wrench flats for positive, repeatable adjustments. Once you dial in your loads, these rings lock down securely and stay put. Hornady backs these dies with a lifetime guarantee against breakage or wear from normal use—a testament to their durability and build quality.
