Description
The RCBS 31301 Full-Length 2-Die Set is purpose-built for reloading .270 Winchester Short Magnum bottleneck rifle cases, giving handloaders a matched pair of dies from RCBS’s Group A die family.
This two-die set pairs a Full-Length Sizer Die with an integrated Expander-Decapping Unit for resizing fired brass and prepping spent primer pockets, alongside a Seater Die with a built-in crimp for seating bullets and finishing loaded rounds to consistent overall length.
Both dies are machined from proprietary case-hardened steel, precision-drilled and reamed to exacting RCBS tolerances, and cut with the standard 7/8″-14 thread pattern that fits the vast majority of popular reloading presses. Engineered specifically for the short, fat .270 WSM bottleneck case, this Group A set provides a solid foundation for handloaders building accurate, reloadable ammunition for the Winchester Short Magnum platform.
Set Includes:
- Full-Length Sizer Die with Expander-Decapping Unit
- Seater Die with built-in crimp
