The RCBS 12601 Full-Length 2-Die Set delivers precision reloading capabilities for .257 Weatherby Magnum cartridges. This Group A die set provides consistent case preparation and bullet seating for magnum rifle cartridges. Engineered for high-pressure magnum loads, these dies maintain tight tolerances through thousands of reloading cycles.

What Makes This Different

RCBS Group A dies feature hardened steel construction with precision-ground surfaces that exceed standard die tolerances. The full-length sizing die completely resizes fired cases to SAAMI specifications, ensuring reliable chambering in any .257 Weatherby Magnum rifle. Unlike basic die sets, this configuration includes both sizing and seating dies with lock rings for consistent setup.

Key Features

• Full-length sizing die resizes entire case body and neck to factory dimensions
• Bullet seating die with built-in roll crimp for secure bullet retention
• Hardened steel construction withstands magnum cartridge pressures
• Precision-ground surfaces maintain .001" tolerances
• Standard 7/8"-14 thread fits all major reloading presses

These dies handle the .257 Weatherby Magnum's high-pressure characteristics while maintaining case life and accuracy. The full-length sizing ensures reliable feeding in bolt-action and semi-automatic rifles. Competition shooters benefit from consistent bullet seating depth, while hunters appreciate the reliable crimping for magazine-fed rifles. The hardened steel construction resists wear from abrasive case materials.
