RCBS Small Base Die Set .243 Winchester - 11403

This two-die reloading set is designed for .243 Winchester bottleneck cases used in semi-automatic, pump, and lever-action rifles. The set includes a Small Base Sizer with Expander-Decapping Unit that resizes cases below SAAMI minimums and removes primers, plus a Regular Seater Die with built-in roll crimper for secure bullet seating. The Small Base design is specifically for tight-chambering firearms requiring minimal case dimensions.
