The RCBS Small Base Die Set is engineered specifically for the discerning marksman who demands precision and reliability from their .223 Remington cartridges. This expertly crafted two-die set is designed to cater to bottleneck type cases, making it an essential tool for those utilizing tight-chambering semi-automatic, pump-action, or lever-action rifles.
This die set includes a Small Base Sizer with an Expander-Decapping Unit and a Regular Seater Die equipped with a Seater Plug. The innovation of the sizer lies in its ability to resize cases below SAAMI minimums. By reducing the shoulder and body by mere thousandths of an inch, this ensures flawless feeding even in firearms known for tighter chambers.
The sizer also performs another critical function—it de-primes your spent cases efficiently, preparing them meticulously for reloading. On the other hand, the included Seater Die features a built-in roll crimper that secures your bullet firmly as it's seated into place. This guarantees stability during recoil—a crucial factor when accuracy counts.
For shooters preferring not to crimp while seating bullets, simply adjust by unscrewing the die until its crimp ring disengages from the case mouth entirely. Such versatility allows you to tailor each round precisely according to your specific needs without compromising on quality or performance.
In essence, whether you're refining ammunition at home or tailoring loads for competition shooting, trust in RCBS's dedication towards excellence—providing tools that stand up under scrutiny where it matters most: out there on range or field alike.
