Hornady 546283 Custom Grade Series IV 2-Die Set 6.5-300 Wby Mag

The Hornady 546283 Custom Grade Series IV 2-Die Set delivers precision reloading capabilities specifically engineered for the 6.5-300 Weatherby Magnum cartridge. This professional-grade die set combines full-length sizing and bullet seating operations with the exacting tolerances demanded by long-range shooters and competitive marksmen.

What Makes This Different

Custom Grade Series IV dies feature Hornady's most precise manufacturing tolerances, held to specifications tighter than standard production dies. The elliptical expander reduces case neck tension variations while the Sure-Loc lock rings eliminate the movement common with standard lock ring designs. Each die undergoes individual inspection and hand-polishing to ensure consistent cartridge dimensions shot after shot.

Key Features

• Full-length sizing die with elliptical expander for uniform neck tension
• Bullet seating die with built-in crimping capability
• Sure-Loc lock rings prevent die movement during adjustment
• Hand-polished interior surfaces for smooth case extraction
• Zip-Spindle design on seating die for easy bullet alignment
• Includes detailed reloading data and instructions
• Compatible with all standard 7/8-14 thread reloading presses

The 6.5-300 Weatherby Magnum's extreme velocity potential requires dies capable of handling the cartridge's unique case geometry and pressure characteristics. These dies maintain consistent shoulder positioning and neck concentricity essential for accuracy at extended ranges. The seating die's micrometer adjustment allows precise bullet depth control, critical when developing loads for different bullet weights and profiles common to this versatile long-range cartridge.
