Product Description
The RCBS 12601 Full-Length 2-Die Set (Group A) for .257 Weatherby Magnum is designed for reloading bottleneck rifle cases to consistent, reliable dimensions. The set includes a Full-Length Sizer Die with an expander-decapping unit to resize the case body, deprime, and expand the neck for bullet seating, plus a Seater Die with bullet seater plug and an integrated roll crimp feature to secure the bullet during seating. The full-length sizer brings cases to SAAMI minimum cartridge dimensions and uses venting to help prevent case damage from trapped air or excessive lubricant while maintaining tight headspace tolerances.
