RCBS Full Length 2 Die Set .223 Rem. / 5.56mm Nato

• Full-Length Sizing for Reliable Chambering: The full-length sizer returns .223 Remington and 5.56 NATO brass to minimum cartridge dimensions, which helps loaded rounds chamber smoothly in a wide range of rifles and supports dependable feeding in repeat-use brass.
• Two-Die Rifle Set: This set combines a sizing die and a seating die in a straightforward format that covers the core steps of bottleneck rifle reloading without adding unnecessary complexity to the bench.
• Expander-Decapping Unit: The sizing die de-primes the case and expands the neck in the same operation, reducing handling between steps and helping maintain consistent neck condition before bullet seating.
• Built-In Roll Crimp Seating Die: The seater die can apply a roll crimp as the bullet is seated, which is useful when loading ammunition that benefits from added bullet retention during handling, transport, or cycling.
• Standard 7/8"-14 Thread: The industry-standard thread pattern makes the die set compatible with a broad range of reloading presses, so it integrates easily into existing single-stage or progressive setups.

About the RCBS Full-Length Die Set Series

RCBS Full-Length Die Set models are built as practical, general-purpose rifle dies for handloaders who want a conventional two-die setup for bottleneck rifle cartridges. In the RCBS lineup, this series sits as the standard full-length sizing option, offering a simpler and more traditional alternative to specialized bushing, match, or small-base die systems. The design is intended for reloaders who value repeatable case preparation, broad press compatibility, and straightforward adjustment.

Across the series, the core format remains consistent: a full-length sizer die with an expander-decapping unit and a seater die with a bullet seater plug. This layout supports the main operations needed to turn fired brass back into reloadable cases and then seat bullets to the desired depth. RCBS also uses proprietary die steel and holds the sizing geometry to minimum cartridge dimensions, which helps produce ammunition suited to rifles that need dependable chambering rather than brass fitted only to one chamber. For rifle reloaders working with hunting or general shooting ammunition, the series is known for durable construction, conventional setup, and a focus on consistent case sizing and bullet seating.

About the RCBS Full Length 2 Die Set .223 Rem. / 5.56mm Nato

The RCBS Full Length 2 Die Set .223 Rem. / 5.56mm Nato is configured for one of the most widely used small-bore rifle chamberings, making it a practical choice for reloaders building ammunition for sporting rifles, bolt-actions, and other platforms chambered in .223 Remington. Its two-die format keeps the workflow direct: one die handles full-length sizing, decapping, and neck expansion, while the second seats the bullet and can apply a roll crimp in the same step.

The main advantage of this set is its emphasis on full-length sizing. By bringing brass back to minimum cartridge dimensions, the sizing die supports reliable chambering when brass may be used across more than one rifle or when dependable feeding matters more than chamber-specific neck sizing. The integrated expander-decapping unit also reduces extra bench operations, helping maintain an efficient loading routine for high-volume .223 ammunition.

The seating die adds flexibility by combining bullet seating with a built-in roll crimp. That makes it useful for loads where firmer bullet retention is preferred, while still keeping the die set compact and easy to set up. With its steel sizing die, standard 7/8"-14 thread, and conventional adjustment system, this RCBS rifle die set fits naturally into established reloading benches and suits handloaders who want durable tooling for routine .223 Rem. and 5.56 NATO case preparation and bullet seating.

About RCBS

RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. The company name came from Rock Chuck Bullet Swage, Huntington’s original bullet-swaging die, and that origin still reflects the brand’s close connection to practical handloading tools. RCBS focuses on ammunition handloading and reloading equipment for rifle and pistol cartridges, with a product range that includes presses, dies, shell holders, powder measures, and priming tools.

RCBS also offers single-stage, turret, and progressive reloading presses, giving the brand a broad presence across different loading styles, from careful batch work to higher-volume production. The company manufactures reloading tools in Oroville, California, and it became a brand of Hodgdon Powder Company in 2024 after its sale by Revelyst. In the reloading category, RCBS is known for durable bench equipment, conventional die systems, and a long-standing focus on practical tools for cartridge assembly.
