RCBS 31869 Supreme Die Set 6mm Creedmoor Full Length Sizing Dies

The RCBS 31869 Supreme Die Set delivers precision reloading capabilities for 6mm Creedmoor cartridges with RCBS's advanced die technology. This two-die set produces consistent, match-grade ammunition that maximizes the 6mm Creedmoor's inherent accuracy potential.

What Makes This Different

The Supreme series features RCBS's tightest manufacturing tolerances, with dies machined to within 0.0002 inches for exceptional concentricity. Unlike standard die sets that may introduce runout, these dies maintain bullet alignment throughout the sizing and seating process. The precision-ground chambers and expander balls ensure consistent neck tension and optimal bullet release.

Key Features

• Full-length sizing die with precision-ground chamber for consistent case dimensions
• Bullet seating die with built-in roll crimp for secure bullet retention
• Hardened steel construction with corrosion-resistant finish
• Includes shell holder #43 and detailed reloading instructions
• Compatible with all standard 7/8-14 TPI reloading presses
• Precision expander ball maintains proper neck tension
• Lock rings with set screws for repeatable die adjustments

This die set handles the 6mm Creedmoor's moderate case capacity and 30-degree shoulder angle with consistent results across multiple firings. The full-length sizing die accommodates cases fired in different chambers, making it suitable for bolt-action rifles, AR-10 platforms, and precision competition firearms. Proper case preparation with these dies supports the 6mm Creedmoor's capability for sub-MOA accuracy at extended ranges.
