RCBS MatchMaster .300 Win Mag Full-Length Bushing Die Set

RCBS MatchMaster Competition Die Set

The MatchMaster full-length bushing die set represents the pinnacle of RCBS reloading technology, purpose-built for shooters who demand precision ammunition for long-range competition and hunting.

Design and Function

This die set builds on the proven foundation of RCBS Gold Metal dies, incorporating a full-length bushing system that provides superior control over case neck sizing. The bushing design allows you to select the exact neck diameter needed for your specific application, ensuring consistent bullet fit and alignment shot after shot.

Key Features

• Full-length bushing die system for precise neck control
• Interchangeable bushings to fine-tune neck tension
• Competition-grade construction for demanding shooters
• Consistent case sizing for improved accuracy
• Compatible with standard reloading presses

Proper Setup

To select the correct neck bushing size, measure the outside neck diameter of a loaded cartridge and subtract .002" to .003" to allow for natural brass spring back. This small clearance ensures reliable chambering while maintaining the tight tolerances necessary for precision shooting.

Whether you're preparing ammunition for F-Class competition, long-range hunting, or benchrest shooting, the MatchMaster die set delivers the consistency that separates good groups from exceptional ones.
