RCBS 20704 Roll Crimp 3-Die Set Group C .444 Marlin Reloading Dies

The RCBS 20704 Roll Crimp 3-Die Set delivers precision reloading capabilities specifically engineered for .444 Marlin cartridges. This Group C die set provides handloaders with the tools needed to produce consistent, accurate ammunition for hunting and target shooting applications.

What Makes This Different

RCBS Group C dies feature hardened steel construction with precise machining tolerances that ensure consistent case dimensions and bullet seating depth. The roll crimp design creates a secure bullet hold while maintaining proper case mouth tension, unlike standard taper crimp dies that can distort case walls. Each die undergoes individual inspection and testing to meet RCBS quality standards for dimensional accuracy and surface finish.

Key Features

• Three-die set includes full-length sizing die, expander die, and roll crimp seating die
• Hardened steel construction with carbide sizing ring for extended service life
• Roll crimp design provides secure bullet retention without case distortion
• Precision-machined threads and chambers ensure consistent case dimensions
• Compatible with all standard 7/8-14 thread reloading presses

The roll crimp seating die creates the proper case mouth crimp essential for .444 Marlin performance in lever-action rifles. The full-length sizing die returns fired cases to SAAMI specifications, while the expander die ensures proper bullet seating tension. This combination produces ammunition that feeds reliably through tubular magazines and delivers consistent chamber pressure for optimal accuracy.
