Description

The Redding Expander Mandrel 0.2230" is a precision reloading tool used to uniform and expand the inside diameter of cartridge case necks. It helps create consistent neck tension, which is critical for achieving accurate and repeatable ammunition performance.
 

Best Suited For

  • Precision reloaders seeking tight control over neck tension
  • Shooters loading .22 caliber cartridges (e.g., .223 Rem, 5.56 NATO variants depending on setup)
  • Users working with turned or annealed brass
  • Benchrest and long-range shooters needing consistent bullet seating tension
  • Reloaders using bushing dies or mandrel-based sizing systems

When To Use It

  • After neck sizing or full-length sizing to set final neck ID
  • When brass necks are inconsistent or slightly undersized
  • During precision load development
  • After neck turning, to restore correct internal diameter
  • When you want repeatable neck tension across batches

👉 Often used as a final step before bullet seating.
