RCBS MatchMaster Full-Length Bushing Die Set .308 Winchester 15508

The RCBS 15508 MatchMaster Full-Length Bushing Die Set delivers precision reloading for .308 Winchester cartridges with interchangeable neck bushing technology. This professional-grade die set enables handloaders to control neck tension with unprecedented accuracy, producing match-quality ammunition that rivals factory premium loads.

What Makes This Different

Unlike standard full-length dies that overwork brass, the MatchMaster system uses interchangeable titanium nitride-coated bushings to size only the neck portion requiring adjustment. The floating carbide expander eliminates the need for case neck lubrication while the micrometer seating die provides 0.001-inch bullet seating adjustments. This modular approach extends brass life by 40-60% compared to conventional sizing methods.

Key Features

• Interchangeable TiN-coated neck bushings for precise tension control
• Floating carbide expander ball eliminates neck lubrication requirements
• Micrometer seating die with 0.001-inch incremental adjustments
• Full-length sizing die maintains proper headspace dimensions
• Compatible with all standard 7/8-14 TPI reloading presses
• Includes sizing die, seating die, and shell holder
• Titanium nitride coating resists wear and corrosion

Competitive shooters rely on the MatchMaster's consistent neck tension to achieve sub-MOA accuracy in F-Class and benchrest competitions. The system maintains uniform bullet grip across multiple firings, critical for long-range precision work where velocity variations of 5-10 fps can mean the difference between center X and outer scoring rings. Hunters benefit from the improved concentricity, extending effective range for ethical shots on game animals.
