The RCBS 6.5x55 X Full Length Die Set (Model: R38412) is a premium mechanical reloading toolset designed specifically for the 6.5x55mm Swedish Mauser bottleneck cartridge. Machined from heat-treated proprietary steel, this two-die set is engineered to solve the common issue of case stretching during the resizing process. By utilizing a patented internal mandrel system, the set controls the flow of brass during sizing, effectively eliminating the need for repeated case trimming after an initial preparation step. This system extends the overall service life of your brass cases while maintaining highly consistent dimensions for reliable chambering.

Key Features

• Patented X-Die Mandrel: Controls case growth during sizing by making contact with the case mouth, preventing the brass from flowing forward and lengthening.
• Two-Die Set Components: Includes one X-Die Full-Length Sizer featuring an integrated decapping pin with an expander mandrel, and one Standard Bullet Seating Die.
• Extended Brass Life: Minimizes the thinning of the brass neck and shoulder area by stopping the continuous cycle of growth and trimming.
• Universal Press Compatibility: Features standard threading to fit seamlessly into the vast majority of single-stage and progressive reloading presses.

Who is the Rcbs 6.5x55 X Full Length Die Set for?

• Precision rifle reloaders shooting 6.5x55mm Swedish Mauser — who require a specialized 6.5x55 reloading die set compatible with standard 7/8"-14 thread presses to maintain highly consistent headspace and neck tension for accurate handloads.
• High-volume handloaders — who want to streamline their workflow by eliminating the repetitive step of case trimming, utilizing an X-Die system that requires trimming the brass .020 inches below maximum case length only once before the first resizing.

Less suitable for: Handloaders reloading alternative 6.5mm cartridges, as this 6.5x55 reloading die set cannot be adjusted or modified to size 6.5 Creedmoor or 6.5 PRC brass; it is also unsuitable for dry, non-lubricated operation, which requires a carbide-style straight-wall sizing die instead.
