RCBS 11408 MatchMaster Full-Length Bushing Die Set .243 Winchester

The RCBS 11408 MatchMaster Full-Length Bushing Die Set delivers precision neck tension control for .243 Winchester cartridges. This advanced die system allows handloaders to fine-tune bullet grip through interchangeable bushings, producing ammunition that consistently outperforms factory loads.

What Makes This Different

Unlike standard full-length dies that overwork brass necks, the MatchMaster system uses precision bushings to control neck tension within 0.001 inches. The modular design eliminates the guesswork in achieving optimal bullet seating force. Competition shooters report improved ES/SD numbers and extended brass life compared to conventional die sets.

Key Features

• Interchangeable bushing system for precise neck tension control
• Full-length sizing maintains proper headspace and chamber fit
• Hardened steel construction with precision-ground surfaces
• Compatible with standard 7/8-14 thread presses
• Includes sizing die, seating die, and shell holder
• Micrometer seating stem for repeatable bullet depth
• Heat-treated components resist wear and maintain tolerances

The MatchMaster system excels in precision rifle applications where consistent ammunition performance matters. Benchrest competitors rely on the controlled neck tension to minimize velocity variations shot-to-shot. The full-length sizing ensures reliable feeding in semi-automatic platforms while maintaining the accuracy benefits of neck bushing technology. Cases sized with this die set chamber smoothly in match-grade barrels without excessive bolt force.
