RCBS 28001 Full-Length 2-Die Set 6mm ARC

The RCBS 28001 Full-Length Die Set is a two-die reloading set purpose-built for the 6mm ARC bottleneck cartridge. The set is built around a Full-Length Sizer Die with an integrated Expander-Decapping Unit and a matching Seater Die, covering case sizing, decapping, and bullet seating in a single matched pair.

The Full-Length Sizer Die resizes the full case body and shoulder back to spec, while the built-in expander-decapping unit knocks out the spent primer and sets correct neck tension in the same stroke. The Seater Die then seats bullets to your chosen depth with repeatable, concentric alignment. As with all RCBS dies, the 28001 is machined to tight tolerances for consistent performance and is intended for bottleneck case reloading only.

The 6mm ARC was developed as an efficient, high-ballistic-coefficient round for the AR-15 platform, and this RCBS set gives handloaders the dedicated tooling to bring fired brass back to spec and reload it accurately. Dies ship with a factory rust-inhibitor coating that should be wiped off before use. This RCBS 28001 is sold as a complete two-die set for the 6mm ARC cartridge.
