RCBS Small Base Die Set - Group A - .223 Remington The RCBS Small Base Die Set for .223 Remington is a precision two-die reloading set engineered specifically for bottleneck type cases used in tight-chambering semi-automatic, pump, or lever-action rifles. The set includes a Small Base Sizer Die with an Expander-Decapping Unit and a Regular Seater Die with Seater Plug. The Small Base Sizer resizes cases to slightly below SAAMI minimums, reducing the shoulder and body by a few thousandths of an inch to ensure reliable feeding and chambering in tight-chamber rifles while simultaneously de-priming spent cases. The Seater Die features a built-in roll crimper that secures the bullet at the same time it is seated. For applications where crimping is not desired, simply unscrew the die until the crimp ring no longer engages the case mouth.
