Description
The RCBS 11131 Small Base Sizer Die is expertly designed for bottleneck cases, ensuring flawless operation in tight-chambering semi-automatic, pump, or lever-action firearms. This precision die resizes your .223 Rem/5.56 NATO cases below SAAMI minimums, effectively reducing the shoulder and body dimensions by a few thousandths. Additionally, it de-primes cases for hassle-free reloading. Please note: this die is not recommended for use with bolt-action rifles, making it ideal for dedicated semi-automatic reloading enthusiasts.
