RCBS 15569 Supreme Die Set .308 Winchester 2-Die Full Length

The RCBS 15569 Supreme Die Set delivers precision reloading capabilities for .308 Winchester cartridges with advanced carbide technology and enhanced case forming. This two-die set combines full-length sizing and bullet seating operations in one comprehensive package designed for high-volume reloaders.

What Makes This Different

The Supreme series incorporates RCBS's titanium nitride coating on critical surfaces, reducing friction and extending die life beyond standard steel dies. Each die features precision-machined tolerances of ±0.0005 inches, ensuring consistent cartridge dimensions shot after shot. The advanced expander system prevents case neck splitting while maintaining proper bullet tension.

Key Features

• Titanium nitride coating reduces sizing force by 25% compared to standard dies
• Full-length sizing die with carbide expander button for smooth case extraction
• Bullet seating die with built-in roll crimp for secure bullet retention
• Precision-machined from hardened steel for dimensional consistency
• Compatible with all standard 7/8-14 thread reloading presses
• Includes detailed instructions and load data reference guide
• Hex lock rings prevent accidental adjustment during reloading sessions

Bench rest competitors rely on this die set's ability to maintain consistent cartridge overall length within 0.002 inches across hundreds of rounds. The full-length sizing ensures reliable chambering in semi-automatic rifles, while the seating die's micrometer adjustment allows precise bullet depth control. Weather-resistant coating prevents corrosion during long-term storage in humid conditions.
