Hornady 545100 Match Grade Die Set .223 Rem 2-Die Reloading Kit

The Hornady 545100 Match Grade Die Set delivers precision reloading capabilities for .223 Remington cartridges, engineered to produce match-quality ammunition with consistent case preparation and bullet seating. This professional-grade die set enables handloaders to achieve superior accuracy and case life through Hornady's proven manufacturing standards.

What Makes This Different

The Match Grade series incorporates tighter manufacturing tolerances compared to standard reloading dies, with chambers honed to within 0.0002 inches for consistent case sizing. The full-length sizing die features an elliptical expander that reduces case neck tension variations by up to 50% versus conventional expanders. Heat-treated steel construction and precision-ground surfaces ensure dimensional stability across thousands of reloading cycles.

Key Features

• Full-length sizing die with elliptical expander for uniform neck tension
• Competition-grade bullet seating die with micrometer adjustment
• Heat-treated alloy steel construction rated for 10,000+ sizing operations
• Sure-Loc lock rings prevent die movement during high-volume reloading
• Internal case neck polishing reduces brass work hardening
• Compatible with all standard 7/8-14 TPI reloading presses
• Includes detailed setup instructions and load data references

Match-grade reloaders report improved group consistency when switching from standard dies to this precision set, particularly beneficial for competitive shooting and long-range applications. The micrometer seating die allows bullet depth adjustments in 0.001-inch increments, enabling fine-tuning for optimal accuracy in bolt-action rifles and AR-15 platforms. Case life typically increases 20-30% due to the controlled sizing process that minimizes brass stress.
