The RCBS 6.5 Rem Mag Full Length Die Set (Model: R33401) is a precision-engineered reloading tool designed for bottleneck rifle cartridges. This two-die set resizes fired 6.5mm Remington Magnum brass and seats new bullets to SAAMI minimum cartridge dimensions, ensuring reliable chambering and cycling. Machined from polished and heat-treated proprietary steel, these dies are built to withstand the high pressures of the reloading process while maintaining tight tolerances.

The set consists of a Full-Length Sizer Die and a Bullet Seating Die. The sizer die features an integrated expander-decapping unit to de-cap spent primers and expand the case mouth, alongside built-in air vent holes that prevent case shoulder buckling or dimpling from trapped air or excess lubricant. The bullet seating die is equipped with a finely machined seater plug and an integrated roll crimper to guide, seat, and secure the bullet at the correct depth.

Key Features

• Full-Length Sizing: Sizes the entire exterior of the fired brass case back to factory dimensions, making it compatible with any standard chamber.
• Integrated Decapping and Expanding: The sizer die depresses the spent primer and expands the neck mouth in a single stroke.
• Air Vent Holes: Machined vent holes in the sizer die prevent damage to the case shoulder caused by trapped air or pocketed lubricant.
• Bullet Seating and Crimping: The seating die features a built-in roll crimper and adjustable seater plug to secure the bullet firmly.
• Steel Construction: Made from polished, heat-treated proprietary steel for long-term durability.

Who is the Rcbs 6.5 Rem Mag Full Length Die Set for?

• Handloaders reloading for multiple hunting rifles — requires returning fired brass to SAAMI minimum dimensions using the RCBS 6.5mm Remington Magnum full-length die set, ensuring reliable chambering and smooth cycling across various semi-automatic or bolt-action firearms.
• Reloaders utilizing standard reloading presses — integrates seamlessly with standard single-stage and progressive reloading presses via the industry-standard 7/8"-14 thread specification featured on this RCBS 6.5mm Remington Magnum die set.

Less suitable for: Handloaders who shoot brass exclusively out of a single, dedicated bolt-action rifle and want to maximize brass life by avoiding working the shoulder; for this application, a neck-sizing-only die is more suitable than a full-length sizing set. Additionally, because these heat-treated steel dies require case lubrication for every sizing cycle to prevent stuck brass, they are not suitable for users seeking a lubrication-free reloading process.
