RCBS neck sizer die for .204 Ruger cartridges. Sizes only the case neck for extended case life and improved accuracy. Steel construction with lifetime warranty.
The RCBS Neck Sizer Die represents precision reloading engineering at its finest. This specialized die sizes only the case neck—leaving the body and shoulder untouched—which preserves case dimensions and extends case life significantly.
Full-length sizing works the entire case, which can shorten case life through repeated work-hardening. Neck sizing addresses only what needs attention: the neck that holds your bullet. This approach is favored by precision shooters who demand consistency and economy from their reloading process.
The .204 Ruger is a specialized varmint cartridge that benefits from the careful case management that neck sizing provides. Whether you're loading for prairie dogs or precision target work, this die delivers the control serious reloaders expect from RCBS.
