Small Base Die Set - Group A - .223 Rem

This two-die set is for bottleneck type cases used in tight-chambering semi-automatic, pump or lever-action rifles. It consists of a Small Base Sizer with an Expander-Decapping Unit and Regular Seater Die with Seater Plug. The sizer resizes cases below SAAMI minimums, reducing the shoulder and body by a few thousandths. It also de-primes the case. The included Seater Die has a built-in roll crimper to secure the bullet at the same time it's seated. To seat bullets without crimping, simply unscrew the die until the crimp ring no longer engages the case mouth.

FAQ

What's the difference between full-length sizing, neck sizing, and small-base sizing dies?

• Full Length Sizing Dies: Resize the entire case to SAAMI minimum dimensions; best for reliability, semi autos, or brass used in multiple rifles.
• Neck Sizing Dies: Resize only the neck; reduces the chances of case head separation and can improve accuracy in bolt action rifles fired in the same chamber.
• Small Base Dies: Resize slightly more than standard full length sizing dies; ideal for semi autos or tight chambers where feeding reliability matters most.
