All RCBS Seater Dies have a built in roll or taper crimper as appropriate for the particular caliber. To seat bullets without crimping, simply unscrew the die until the crimp ring no longer engages the case mouth.
Large, easy to adjust hex lock rings utilize hex head setscrews. Unless otherwise noted, all RCBS Precisioneered Dies have the standard 7/8-14 thread. Dies are packaged in stackable, plastic storage boxes specially designed to protect the dies in shipping. Includes loading data label.
