RCBS 3-Die Roll Crimp Set for .450 Marlin
This complete reloading die set is purpose-built for handloaders working with .450 Marlin straight-wall rifle cartridges. The set includes everything needed to resize, expand, and seat bullets with precision.
What's Included
- Sizer Die: Steel construction sizes cases to proper dimensions and removes spent primers in one operation. Cases must be lubricated before sizing.
- Expander Die: Expands the case to the correct diameter for bullet acceptance and imparts the necessary case mouth flare or bell for reliable bullet feeding.
- Seater Die: Seats bullets to precise depth while applying a roll crimp for secure bullet retention.
Design Philosophy
RCBS engineered this set specifically for straight-wall cartridges like the .450 Marlin, ensuring each die performs its function with the precision handloaders expect. The roll crimp function eliminates the need for a separate crimping step, streamlining your reloading process.
Getting Started
This is a complete die set—no additional dies required for basic reloading operations. Ensure proper case lubrication before sizing to protect both your cases and dies.
