Redding Neck Sizing Bushings .289"

The Redding Neck Sizing Bushings .289" (part number 76289) are precision reloading components engineered for handloaders who demand consistency and minimal neck tension variation across cartridge batches. These bushings represent the critical interface between your sizing die and cartridge neck, directly controlling how uniformly your ammunition chambers and performs downrange.

Built from heat-treated steel and finished with titanium nitride coating, the .289" bushing reduces friction during the sizing stroke while increasing effective surface hardness—a combination that extends bushing life and produces more consistent neck tension shot-to-shot. The titanium nitride treatment is particularly valuable during high-volume loading sessions where repeated sizing cycles generate friction and wear. Redding manufactures neck sizing bushings across a comprehensive range of diameters to accommodate calibers from .17 to .338, allowing precision reloaders to match exact neck dimensions to their specific cartridges and seating requirements.

This .289" bushing is designed for reloaders working with cartridges requiring neck control in that diameter specification—whether full-length sizing, neck-only sizing, or use with Redding's full bushing-style sizing die systems. Handloaders focused on precision rifle ammunition, match-grade loads, or high-round-count training programs benefit most from bushing-based sizing because it isolates neck tension from variations in body diameter, producing tighter velocity spreads and improved grouping consistency compared to conventional die-only sizing.
