Hornady 546351 Custom Grade 2 Die Set 300 PRC Sizing Seater

The Hornady 546351 Custom Grade Series I 2 Die Set delivers precision reloading capabilities specifically engineered for the 300 PRC cartridge. This professional-grade die set includes both full-length sizing and seating dies, enabling handloaders to produce match-quality ammunition with consistent performance characteristics.

What Makes This Different

Hornady's Custom Grade dies feature heat-treated steel construction with precision-machined tolerances that exceed SAAMI specifications. The full-length sizing die incorporates an elliptical expander that reduces case neck tension variations by up to 50% compared to standard ball expanders. Internal geometry matches actual chamber dimensions rather than minimum SAAMI specifications, resulting in improved case life and accuracy potential.

Key Features

• Full-length sizing die with elliptical expander for consistent neck tension
• Seating die with built-in crimping capability and micrometer adjustment
• Heat-treated steel construction with precision-ground surfaces
• Zip-Spindle design on seating die prevents damage to bullet tips
• Sure-Loc lock rings with set screws for repeatable die positioning
• Compatible with all standard 7/8-14 thread reloading presses
• Includes detailed instruction sheet with load data references

The 300 PRC's long-range capabilities demand precise ammunition preparation, and this die set maintains cartridge concentricity within 0.002 inches when properly adjusted. Competition shooters report improved group consistency at extended ranges, while hunters benefit from reliable bullet placement on game at distances exceeding 800 yards. The dies handle both factory brass and once-fired cases effectively, with the sizing die's tapered design reducing extraction force requirements.
