RCBS 18212 Carbine 3-Die Set Group B .357 Mag/.38 Special/.357 Max

The RCBS 18212 Carbine 3-Die Set delivers precision reloading capabilities for three popular revolver calibers in one comprehensive package. This Group B die set handles .357 Magnum, .38 Special, and .357 Maximum cartridges with the reliability RCBS has maintained for over six decades.

What Makes This Different

Unlike standard two-die pistol sets, this carbide three-die configuration includes a dedicated taper crimp die for consistent bullet retention and proper case mouth preparation. The carbide sizing ring eliminates the need for case lubrication during the sizing operation, reducing processing time and preventing contamination. RCBS heat-treats each die to precise specifications, ensuring dimensional stability through thousands of reloading cycles.

The taper crimp die produces uniform bullet seating depth while maintaining proper case mouth tension for reliable feeding in revolvers and lever-action rifles.

The carbide construction resists wear from high-volume reloading sessions.
