RCBS 10301 Full-Length Die Set for 204 Ruger

The RCBS 10301 Full-Length Die Set is designed for reloading .204 Ruger bottleneck cases with consistent, reliable results. This two-die set includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with Bullet Seater Plug. Together, these dies support essential case preparation and bullet seating operations for reloaders who need dependable performance from their .204 Ruger ammunition.
The Full-Length Sizer Die returns cases to SAAMI minimum cartridge dimensions while sizing the outside of the case, removing spent primers, and expanding the neck to accept a new bullet. Its vented design helps prevent case damage caused by trapped air or excessive lubricant during the sizing process. The die also maintains headspace within minimum tolerances, helping avoid unnecessary changes to case body length during full-length sizing. This makes the RCBS 10301 a practical choice for routine case preparation and reliable chambering.
The included Seater Die features a built-in roll crimper that secures the bullet as it is seated. This integrated operation helps streamline the reloading process while supporting consistent bullet placement and cartridge assembly. Built for use with .204 Ruger cartridges, the RCBS 10301 die set combines sizing, decapping, neck expanding, bullet seating, and crimping functions in one purpose-built package. Its full-length configuration is well suited to reloaders who want a complete two-die solution for bottleneck rifle cases. Always follow established reloading procedures, consult current load data, and use the dies only with the appropriate cartridge and equipment.
