Redding Neck Sizing Bushings .333"

The Redding Neck Sizing Bushings .333" (Part No. 76333) are precision reloading components engineered for handloaders who demand exact neck tension control during the ammunition assembly process. These bushings deliver consistent, caliber-specific sizing for cartridges in the .333" diameter range, a critical specification for maintaining uniform case neck concentricity and repeatable bullet seating force shot after shot.

Constructed from heat-treated steel and finished with a titanium nitride coating, these Redding neck sizing bushings provide significantly reduced friction during the sizing stroke while maintaining hardness and longevity under repeated use. The .333" diameter makes them compatible with cartridges scaled for precision rifle applications where neck runout directly affects accuracy and velocity consistency. The titanium nitride surface treatment protects against wear and corrosion, extending bushing life through hundreds of sizing cycles. This product is part of Redding's comprehensive bushing system, which covers calibers from .17 to .338, allowing reloaders to match bushing size precisely to their cartridge specifications.

Reloaders pursuing match-grade ammunition quality—whether for long-range competition, precision hunting, or ammunition development—depend on neck sizing bushings to standardize the critical interface between case neck and bullet. The .333" specification addresses a specific segment of the cartridge market where off-the-shelf bushing sizes may not deliver the required tension. By selecting the correct bushing diameter, shooters eliminate excessive or insufficient neck grip, which translates to tighter velocity spreads, improved bullet runout control, and more consistent point-of-impact downrange. These bushings represent an essential component in any serious hand-loader's die room.
