RCBS 9802 Expander Decapping Unit 5.56mm/.223 Rem Reloading Tool

The RCBS 9802 Expander Decapping Unit streamlines case preparation for 5.56mm/.223 Remington cartridges by combining primer removal and case mouth expansion in a single operation. This precision-engineered tool eliminates the need for separate decapping and expanding steps, reducing reloading time while maintaining consistent case preparation quality.

What Makes This Different

Unlike basic decapping pins that only remove primers, the RCBS 9802 incorporates an expander ball that sizes the case neck to proper dimensions during the decapping stroke. The hardened steel construction resists wear from repeated use across thousands of cases. The unit's precise tolerances ensure uniform neck tension, contributing to more consistent bullet seating and improved accuracy potential.

Key Features

• Combined decapping pin and expander ball eliminates separate processing steps
• Hardened steel construction withstands high-volume reloading operations
• Precision-ground expander ball maintains consistent neck tension
• Compatible with RCBS single-stage and progressive reloading presses
• Caliber-specific design optimized for 5.56mm/.223 Remington cases
• Standard 7/8"-14 thread pattern fits most reloading press ram assemblies
• Replaceable decapping pin reduces long-term maintenance costs

The unit handles both military 5.56mm and commercial .223 Remington brass with equal effectiveness. Reloaders processing mixed headstamp brass benefit from the consistent case preparation this tool provides. The expander ball's controlled expansion prevents case mouth cracking while ensuring proper bullet grip. Competition shooters and high-volume reloaders appreciate the time savings and consistency this combination tool delivers.
