The RCBS .222 Remington Neck Sizer Die (Model: 10930 / R10930) is a precision reloading tool designed specifically for the .222 Remington cartridge. Unlike full-length sizing dies, this neck sizer die resizes only the neck of the fired brass case to snugly hold a new bullet. By leaving the body and shoulder of the case completely untouched, the brass retains the exact fire-formed dimensions of the specific rifle chamber from which it was fired. Manufactured from case-hardened steel, this die features an integrated expander-decapping unit to simultaneously de-prime the case and expand the neck during the sizing stroke.

Key Features

• Targeted Neck Sizing: Resizes only the neck of .222 Remington brass to match a specific rifle chamber, reducing bullet runout and improving overall accuracy.
• Extended Brass Life: Minimizes the working of the brass body and shoulder, dramatically reducing the likelihood of splits and case head separation.
• Integrated Expander-Decapping Unit: Decaps spent primers and expands the case neck in a single manual operation.
• Standard Thread Compatibility: Built with standard 7/8"-14 threading to ensure compatibility with most single-stage and progressive reloading presses.

Who is the Rcbs 222 Rem Neck Sizer Die for?

• Precision target shooters — loading for bolt-action rifles require this neck sizer reloading die to match the precise chamber dimensions of their specific firearm, utilizing the industry-standard 7/8"-14 threading to mount securely into their existing press to minimize cartridge movement upon ignition.
• Varmint hunters — aiming to maximize case longevity during high-volume shooting can use this neck sizer reloading die to process brass with minimal cold-working, utilizing its 7/8"-14 threading to fit their reloading press and prevent premature case head separations in their custom-formed cases.

Less suitable for: Reloaders using semi-automatic, pump-action, or lever-action firearms, reloading brass to be shared across multiple different .222 Rem rifles, or processing brass that has expanded to the point of causing heavy bolt lift and chambering resistance; these scenarios exceed the mechanical limits of neck-only sizing and require a Full-Length Sizing Die or Small-Base Sizing Die instead.
