Description

This professional-grade reloading die set was manufactured by RCBS for the .257 Weatherby Magnum cartridge. Identified as Part Number 12601 and designated as a Group A set, the kit is constructed from precision-machined steel. It includes a full-length sizer die and a seater die, both featuring knurled sections for improved grip during adjustment and black-finished lock rings with brass set screws. The components are housed in the manufacturer’s signature green textured plastic storage case with an embossed RCBS logo on the lid. The interior of the lid contains a pre-printed reloading data grid for user record-keeping. This set is designed for use with a #04 shell holder. No ruler or scale was provided for precise measurements.
