The RCBS .223 Remington Small Base Sizer Die is designed to size bottleneck-type .223 Remington cases used in tight-chambered, semiautomatic, pump or lever-action firearms. It resizes below SAMMI minimums, reducing the shoulder and body by a few thousandths. It also de-primes the case. Not recommended for ammunition used in bolt-action rifles. Die only.
