RCBS 9805 Expander/Decapping Unit for 6mm
RCBS expander/decapping assembly for 6mm cartridges features a carbide expander button with adjustable positioning sleeve. Removes primers and expands case necks in bottleneck cartridges.
RCBS 9805 Expander/Decapping Assembly
This precision reloading component is an essential tool for handloaders working with 6mm bottleneck cartridges. The assembly performs two critical functions in the reloading process: decapping (primer removal) and neck expansion.
Key Features
- Ultra-hard carbide expander button resists wear and maintains consistent performance across thousands of rounds
- Adjustable positioning sleeve allows fine-tuning of neck expansion for optimal fit and concentricity
- Integrated decapping pin efficiently removes spent primers from fired cases
- Compatible with RCBS sizing dies for seamless integration into your reloading setup
How It Works
The expander/decapping assembly mounts in your sizing die and performs its functions as the ram rises. The decapping pin punches out the spent primer while the carbide expander button simultaneously opens the case neck to the proper diameter. The adjustable sleeve gives you control over expansion depth, critical for achieving consistent, accurate ammunition.
Why This Matters
Proper case preparation is foundational to reloading success. This RCBS assembly ensures your cases are properly decapped and expanded, setting the stage for precise bullet seating and reliable performance downrange.
