RCBS Cowboy Carbide Roll Crimp 3 Die Set .38 Special/.357 Mag

The RCBS Cowboy Carbide Roll Crimp 3 Die Set for .38 Special and .357 Magnum is designed for serious handloaders who prioritize precision and durability in their ammunition production. This three-die set is ideal for competitive marksmen and dedicated reloaders who seek consistent and reliable ammunition for revolvers and lever-action rifles. The roll crimping technology ensures that cartridges remain securely assembled under the pressures and vibrations inherent in revolver use.

RCBS carbide dies feature hardened carbide sizing rings that eliminate the need for case lube and significantly extend die lifespan. The roll crimp design seats the bullet while rolling the case mouth inward, creating a mechanical lock that prevents bullet setback, which is crucial for maintaining case integrity during rapid firing cycles. This design enhances the reliability and performance of the ammunition produced.

Reloaders who participate in Cowboy Action Shooting or three-gun competitions will find this set particularly beneficial due to its reliability and quality control. The three-die configuration includes a sizing die, powder-charging die, and roll-crimp seating die, allowing users to efficiently complete loading cycles with minimal setup and maximum consistency between rounds. This set is compatible with standard reloading presses that have a 7/8x14 thread.
