The RCBS MatchMaster Neck Sizing Bushing Die Set for .22-250 Rem (RCBS part no. 10610) sizes the case neck only, leaving the body and shoulder at their fired, fire-formed dimensions. That matters for a bolt-gun handloader working brass that’s only ever fired in one chamber: skipping body sizing means less brass work-hardening and more reloads out of the same cases. The set builds on the RCBS Gold Medal die line and uses an interchangeable bushing to size the neck to the exact tension the load calls for, rather than a fixed expander. Part of RCBS‘s line of reloading dies.

Key Specifications

• The die sizes the case neck only, leaving the body and shoulder at their fired, chamber-fitted dimensions.
• It uses an interchangeable neck bushing instead of a fixed expander, so tension can be matched to the brass.
• Neck-only sizing means less brass work-hardening per firing than a full-length die, useful for cases fired and reloaded in the same rifle.
• The set builds on the RCBS Gold Medal die line, carrying that sizing pedigree into the MatchMaster series.
• The die is machined specifically for .22-250 Rem case dimensions.

Frequently Asked Questions

Will this die resize the whole case? No — it sizes the neck only, leaving the body and shoulder at their fired dimensions, which is why it’s meant for brass fired in the same rifle it will be reloaded for.

Do I need to buy a bushing separately? The die uses an interchangeable neck bushing system so tension can be matched to your .22-250 Rem brass and load.

Why choose neck sizing over full-length sizing? Neck-only sizing skips resizing the body and shoulder, which reduces brass work-hardening and can extend case life for rifles firing the same brass repeatedly.
