RCBS Full Length Die Set for .416 Remington Magnum

The RCBS Full Length Die Set for .416 Remington Magnum gives you everything needed to reload bottleneck rifle cases with precision and consistency. Built around the demanding requirements of the .416 Rem Mag—a powerful magnum cartridge—this three-piece die set brings your brass back to SAAMI specification dimensions, ensuring reliable feeding, consistent headspace, and uniform round-to-round performance for hunting or long-range shooting.

The Full-Length Sizer Die is the workhorse of the set. It resizes the case body and neck to minimum cartridge dimensions, removing the spent primer in one stroke. The die includes built-in vents that prevent case damage from trapped air pockets and excess lubricant—a detail that protects your brass and keeps your reloading workflow smooth. Because headspace is held to tight tolerances during sizing, you avoid unintended changes to case length that can affect accuracy and bolt fit.

The Seater Die completes the operation with a built-in roll crimper that secures the bullet in place as it's seated. This integrated crimp ensures consistent bullet pull and helps maintain pressure uniformity across your ammunition lot—critical for magnum cartridges where consistency matters. The included Bullet Seater Plug allows you to dial in the exact seating depth your load demands.

Whether you're preparing premium hunting ammunition for the .416 Rem Mag or assembling precision rifle rounds for the range, this RCBS die set delivers the control and repeatability that experienced reloaders expect.
