RCBS Full Length Die Set .25 WSSM 2-Die Group A

The RCBS Full Length Die Set is a two-die reloading set built specifically for the .25 Winchester Super Short Magnum bottleneck rifle cartridge. Part of RCBS's Group A sizing classification, this die set includes a Full-Length Sizer Die with an integrated Expander-Decapping Unit and a matching Seater Die with a bullet seater plug, giving handloaders everything required to deprime, resize, expand the case mouth, and seat projectiles on a single-stage press.

Both dies are machined from hardened steel and cut with the industry-standard 7/8x14 thread pattern, making them compatible with the vast majority of reloading presses. The full-length sizer pushes fired .25 WSSM brass all the way back to factory specifications, while the seater die seats bullets to your chosen overall length with consistent depth. Identified as RCBS part number 12401, this Group A die set provides a reliable foundation for handloading accurate .25 WSSM ammunition.
