The RCBS 6mm Creedmoor Full Length Die Set (Model 31801) is a premium, mechanical reloading tool designed to resize spent brass cases and seat new bullets for bottleneck 6mm Creedmoor rifle cartridges. Machined from high-grade proprietary die steel, this set provides precision reloading capabilities for handloaders seeking consistent chambering and uniform bullet tension. Operating entirely mechanically, the set is fully compatible with standard Australian handloading setups without requiring electrical power or regulatory compliance approvals.

Key Features

• Full-Length Sizing Die: Resizes the exterior of the brass casing to SAAMI minimum dimensions, ensuring smooth chambering. Features built-in vents to prevent trapped air or excess lubricant from denting the brass.
• Expander-Decapping Unit: An integrated decapping rod removes spent primers while expanding the case neck to the precise inner diameter required to secure a new bullet.
• Bullet Seating Die: Features an integrated roll crimper and bullet seating plug, allowing handloaders to seat the bullet to the correct depth and apply a uniform crimp in a single mechanical stroke.
• Durable Construction & Storage: Built to last a lifetime under standard operating conditions and packaged in the signature RCBS durable green plastic storage box.

Who is the Rcbs 6mm Creedmoor Full Length Die Set for?

• Competitive shooters — requires a standard 7/8"-14 thread interface to consistently resize spent brass cases to SAAMI minimum dimensions on standard reloading presses, ensuring reliable feeding and uniform neck tension during high-velocity precision rifle matches.
• Hunters — need a lightweight 1.18 lbs dual-die reloading kit to produce high-precision, roll-crimped 6mm Creedmoor cartridges that chamber reliably in standard rifle chambers in demanding field conditions.
• Long-range tactical marksmen — utilize the 7/8"-14 thread die system to precisely seat heavy, aerodynamic 6mm Creedmoor bullets to exact overall lengths, optimizing downrange ballistic performance and velocity consistency.

Less suitable for: handloaders reloading parent cases or alternative calibres like the 6.5 Creedmoor, as this 6mm Creedmoor reloading die set is strictly configured for 6mm Creedmoor bottleneck brass and cannot resize other dimensions; these users require dedicated calibre-specific die sets or specialized bushing-style match dies for adjustable neck-tension control.
