The RCBS Neck Sizer Die (RCBS part no. 10630) is a standalone die for .22-250 Rem that resizes only the neck of a fired case, leaving the body and shoulder alone. It’s built for reloaders who fire and reload brass in the same bolt-action rifle and want to minimize how much the case gets worked on each pass through the press. Because the die only touches the neck, brass tends to last longer and chambers tighter around the case for a more consistent, accurate reload at the bench.

Key Specifications

• Sized specifically for .22-250 Rem brass.
• Resizes the case neck only, leaving the body and shoulder dimensions the fired chamber already formed.
• Includes a built-in Expander-Decapping Unit that de-primes the case and expands the neck to the correct inside diameter in one pass.
• Working only the neck reduces brass stress on each firing, which can help extend case life over repeated reloads.
• Machined from hardened steel for long service life at the bench.
• Backed by RCBS’s lifetime guarantee on materials and manufacturing.
• Sold as a die only — no seater die or shell holder is included in the box.
• Threads into any standard 7/8-14 single-stage or turret press.

Frequently Asked Questions

How is a neck sizer die different from a full-length die? It resizes only the case neck and leaves the body and shoulder as formed by the chamber, instead of resizing the whole case.

Is a shell holder included? No. This is a die only; a shell holder matching the cartridge is sold separately.

What cartridge does this die fit? It’s machined specifically for .22-250 Rem and isn’t interchangeable with other chamberings.
