The Forster Neck Tension Gage NTG-224 is an inspection tool for reloaders to screen and sort .22 caliber brass before the bullet seating operation. It provides measured feedback to help establish consistent inside neck diameters and neck tension for reliable bullet release. The tool features multiple stepped diameters, each etched on the metal body for clear identification.
