RCBS Full Length 2 Die Set .338-06, 338-06 A-Square

• Full-Length Sizing and Seating Set: This 2-die rifle set combines a full-length sizing die with a seating die, giving handloaders the core tools needed to resize brass, remove spent primers and seat bullets for dependable chambering.
• Built-In Roll Crimp: The seating die applies a roll crimp as the bullet is seated, which helps keep bullet retention consistent and is especially useful for hunting ammunition that may see recoil in the magazine or rough field handling.
• SAAMI-Minimum Sizing: The full-length sizer brings cases back to SAAMI minimum cartridge dimensions, helping fired brass feed and chamber more smoothly across different rifles.
• Standard 7/8"-14 Thread: The dies fit presses that use the common 7/8"-14 thread, making the set easy to integrate into many existing reloading benches without special adapters.
• Made in USA Steel Construction: Steel die bodies made in the USA support long service life and repeatable adjustment, which matters when loading batches of rifle ammunition with consistent setup.

About the Full-Length Die Set Series

RCBS Full-Length Die Set models are built for handloaders who want a straightforward, durable setup for bottleneck rifle cartridges. In the RCBS die lineup, these sets sit as the traditional all-purpose choice: a practical option for reloaders loading hunting ammunition, general rifle rounds and repeat batches of brass that need to chamber reliably. The format centers on a full-length sizing die paired with a bullet seating die, covering the essential operations needed for most conventional rifle loading workflows.

The series is designed around dependable case preparation rather than specialized benchrest adjustment. RCBS uses steel die construction and standard press fitment, keeping the system compatible with widely used reloading presses. For bottleneck rifle cartridges, the full-length sizer de-primes, resizes the case body and neck, and expands the neck for bullet seating, while the seater die handles bullet placement and can apply a roll crimp. That combination makes the series well suited to reloaders who prioritize repeatable setup, broad press compatibility and ammunition that feeds and chambers with minimal fuss in the field or on the range.

About the RCBS Full Length 2 Die Set .338-06, 338-06 A-Square

The RCBS Full Length 2 Die Set .338-06, 338-06 A-Square is configured for reloaders working with the .338-06 A-Square, a bottleneck rifle cartridge often chosen for hunting applications where a heavier .338 caliber bullet is paired with a familiar .30-06-based case format. In practical use, this die set is aimed at producing ammunition that chambers consistently and holds up well in rifles used for field shooting rather than only controlled bench work.

The set includes the two core dies most reloaders need. The full-length sizing die resizes the case body, removes the spent primer and expands the neck, helping fired brass return to dimensions suited to reliable chambering. That matters when brass may be used across repeated loading cycles or when dependable feeding is more important than minimizing every bit of sizing. The seating die then seats the bullet and applies a roll crimp, which can help maintain bullet retention under recoil and during transport.

With its standard 7/8"-14 thread, the set works with a wide range of presses, so it fits easily into established reloading setups. The steel sizing die construction supports long-term use, while the standard adjustment layout keeps setup familiar for reloaders who prefer conventional dies over bushing-based systems. For anyone loading .338-06 A-Square ammunition for hunting or general rifle use, this RCBS set focuses on practical, repeatable case sizing and bullet seating without adding unnecessary complexity.

About RCBS

RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. The company built its reputation around ammunition handloading tools and remains closely associated with rifle and pistol reloading equipment. The RCBS name came from “Rock Chuck Bullet Swage”, referring to Huntington’s original bullet-swaging die, and that origin still reflects the brand’s focus on practical tools for serious reloaders.

Today, RCBS is based in Oroville, California, United States, and its product range includes presses, dies, shell holders, powder measures and priming tools. The company is particularly well known for producing equipment that supports complete loading workflows, from case preparation through bullet seating. For die sets such as this one, RCBS is valued for its long-standing specialization in durable, conventional reloading tools made for repeat use on the bench.
