Redding Titanium Nitride Bushing/.257
The Redding Titanium Nitride Bushing/.257 is a precision neck-sizing bushing engineered for reloaders who demand consistent, friction-free ammunition assembly. Built on a foundation of heat-treated steel and finished with a titanium nitride coating, this bushing reduces sizing friction while maximizing surface hardness—critical factors when you're working toward tight case neck tolerances and repeatable round-to-round performance. The .257 size fits standard Redding reloading dies and is part of Redding's comprehensive bushing lineup, available in .001" increments across the full caliber range.
Titanium nitride coating delivers real benefits for high-volume reloaders and precision shooters alike. The harder surface means less die wear over thousands of cycles, smoother bushing operation, and easier cleanup between sizing runs. If you're loading for match-grade rifles, wildcats, or any situation where neck tension directly affects accuracy, a quality bushing like this one pays for itself in consistency and extended die life.
Redding bushings are sized by the last three digits of the part number (RD76XXX), making it straightforward to swap sizes if your needs change. Whether you're working up loads for long-range hunting, competition, or precision bench shooting, having the right bushing size ensures your dies work as they're meant to—without fighting friction or guessing at proper neck fit.

Frequently Asked Questions
What does the .257 size mean, and will it fit my Redding die?
The .257 designation indicates the internal bushing diameter. This bushing is designed to work with Redding reloading dies and neck-sizing systems that accept standard Redding bushings. Verify your die manual or contact Redding to confirm compatibility with your specific setup.
Why choose a titanium nitride bushing over a standard bushing?
The titanium nitride coating hardens the bushing surface and reduces friction during the sizing process. This means smoother operation, less wear on both the bushing and your die, and easier maintenance—especially valuable if you're loading high volumes or working with tight tolerances.
Are Redding bushings available in other sizes?
Yes. Redding produces bushings in .001" increments across a range from .185" through .368", so you can find the exact size for your cartridge and desired neck fit. The part number format (RD76XXX) makes it easy to identify and order the right size.
