The RCBS 338-06 Full Length Die Set (Model 16701) is a premium two-die reloading system designed to process bottleneck rifle cartridges back to SAAMI minimum cartridge dimensions. Manufactured in the USA from proprietary hardened die steel, this set includes a Full-Length Sizer Die and a Bullet Seating Die. It provides a highly durable and precise solution for restoring fired brass to factory tolerances, ensuring smooth chambering and consistent ignition in bottleneck rifle chambers.

Key Features

• Full-Length Sizing: The sizer die resizes the case body, pushes back the shoulder, and expands the inner neck diameter of .338-06 brass to the exact tension required for seating new bullets.
• Integrated Expander-Decapping Unit: Easily decaps spent primers while preparing the case neck in a single stroke.
• Vented Case Sizing: Specialized vents in the sizing die prevent trapped air pockets or excess case lubricant from denting the brass case shoulder.
• Bullet Seating and Crimping: The bullet seating die features an adjustable seater plug and an integrated roll crimper to seat the projectile and secure it tightly.
• Universal Threading: Designed with standard 7/8"-14 threads to mount directly into standard single-stage and progressive reloading presses.

Who is the Rcbs 338-06 Full Length Die Set for?

• Handloaders reloading for .338-06 bottleneck rifles — requires a dedicated 2-die set engineered specifically to resize and seat bullets for the .338-06 / .338-06 A-Square calibre using standard 7/8"-14 threads that thread directly into standard reloading presses.
• Reloaders producing ammunition for multiple firearms — requires a full-length sizing capability to return fired cases to SAAMI minimum dimensions, ensuring reliable chambering across different rifle chambers rather than sizing only the neck for a single firearm.

Less suitable for: straight-walled cartridges, which require a 3-die set with a dedicated expanding die to prevent brass buckling, or for reloaders who do not use case lubrication, which is strictly required to prevent cases from seizing inside these steel dies. Reloaders looking to resize only the brass neck for a single bolt-action rifle should use a dedicated neck-sizing die instead.
