RCBS 29501 Full-Length 2-Die Set .30-378 Weatherby Mag

Reload the .30-378 Weatherby Magnum with confidence using the RCBS 29501 Full-Length 2-Die Set from RCBS's Group A series. Purpose-built for bottleneck rifle cases, this two-die set gives the reloader everything needed to size, deprime, expand, seat, and crimp in a straightforward, repeatable workflow.

The set includes a Full-Length Sizer Die with an integrated Expander-Decapping Unit that resizes the case body and neck while removing spent primers, paired with a Seater Die fitted with a Bullet Seater Plug for precise bullet seating. Both dies are machined from proprietary RCBS die steel and feature large, easy-to-adjust hex-lock rings for secure, repeatable settings run after run.

Standard 7/8"-14 threading ensures broad compatibility with the vast majority of single-stage and progressive reloading presses. Whether you are loading for long-range benchrest, big-game hunting, or simply chasing the accuracy potential of the belted .30-378 Weatherby Magnum, this Group A die set delivers the precision and durability RCBS is known for.
