RCBS 24212 Carbine 3-Die Set Group B .460 S&W Magnum Reloading Dies

The RCBS 24212 Carbine 3-Die Set delivers precision reloading capabilities for .460 S&W Magnum cartridges. This Group B die set handles the unique requirements of large magnum revolver cartridges with consistent results shot after shot.

What Makes This Different

RCBS Group B carbine die sets feature hardened steel construction specifically engineered for straight-wall magnum cartridges. The three-die configuration includes a full-length sizing die, powder-through expanding die, and bullet seating die with built-in roll crimp. This setup produces more consistent neck tension and bullet alignment compared to standard two-die sets, critical for achieving optimal accuracy with heavy .460 S&W loads.

Key Features

• Full-length sizing die ensures consistent case dimensions and reliable chambering
• Powder-through expanding die allows efficient progressive reloading workflow
• Bullet seating die with integrated roll crimp prevents bullet setback under recoil
• Hardened steel construction withstands pressures up to 65,000 PSI
• Standard 7/8-14 threads fit all major reloading press brands
• Includes detailed instructions and load data recommendations
• Precision-ground surfaces maintain tolerances within 0.001 inches

The .460 S&W Magnum demands precise reloading techniques due to its substantial case capacity and high operating pressures. This die set handles bullets from 200 to 395 grains while maintaining consistent overall length and proper case mouth tension. The integrated crimp feature proves essential for heavy recoiling loads, preventing bullet migration during firing sequences.
