RCBS Full Length Die Set - .27 Nosler

The RCBS Full Length Die Set for .27 Nosler (MPN 26401) is a precision two-die reloading system engineered for handloaders working with bottleneck rifle cartridges. This set delivers the dimensional consistency and headspace control required for match-grade ammunition, combining a full-length sizer die with expander-decapping unit and a seater die with bullet seater plug. The full-length sizer brings cases to SAAMI minimum cartridge dimensions, sizing the case body, removing spent primers, and expanding the neck to accept bullets.

The sizer die incorporates dual vents to prevent case damage from trapped air and excess lubricant—a design feature that reduces deformation and extends case life across multiple reloading cycles. Headspace is held to minimum tolerances, maintaining consistency without shifting dimensions that can compromise accuracy or create dangerous pressure conditions. The seater die allows precise bullet seating depth control, critical for achieving the tight velocity spreads demanded by long-range precision shooting. This die set is optimized for the .27 Nosler, a modern magnum cartridge known for high velocity and extended-range ballistics.

This set is designed for reloaders who handload for precision rifle applications—competitive long-range shooting, hunting large game at extended distances, and ammunition development where velocity consistency and tight shot grouping are non-negotiable. Serious handloaders working with magnum cartridges depend on RCBS die sets to maintain batch-to-batch uniformity and eliminate variables that degrade accuracy. The .27 Nosler's popularity in the precision rifle community makes a dedicated, properly engineered die set essential for anyone committing to this cartridge.
