Rcbs Full Length Die Set - Group D Bottleneck Rifle Cartridge .416 Rigby
The RCBS Full Length Die Set for .416 Rigby is purpose-built for reloaders working with this powerful bottleneck rifle cartridge. Whether you're handloading ammunition for a dangerous game rifle or precision long-range hunting, this die set handles the full-length sizing and seating operations needed to produce consistent, safe ammunition. RCBS has engineered this Group D set specifically for the geometry and headspace demands of the .416 Rigby, bringing fired cases back to SAAMI minimum dimensions and preparing them for accurate bullet seating.
Full-length sizing is the foundation of reliable ammunition, especially for magnum rifle cartridges like the .416 Rigby. This die set includes a Full-Length Sizer Die that resizes the case body, decaps spent primers, and expands the neck to accept your bullet. The die features air vents to prevent case damage from trapped air and lubricant buildup—a detail that matters when you're working with premium brass and expect consistent performance downrange. Headspace is held to minimum tolerances, so you're not inadvertently stretching case length and compromising case life.
The included Seater Die finishes the job with a built-in roll crimper that secures the bullet as you seat it, creating a uniform, reliable union between bullet and case. This combination—precise sizing plus simultaneous seating and crimping—is the reloader's pathway to ammunition that chambers smoothly, shoots accurately, and handles the recoil of a .416 Rigby without separation or failure.
