Redding Titanium Nitride Bushing/.331
The Redding Titanium Nitride Bushing/.331 is a precision neck-sizing bushing designed for reloaders who demand reduced friction and maximum die longevity. This .331-inch bushing is built from heat-treated steel and coated with titanium nitride—a hard surface treatment that lowers sizing resistance and extends bushing life compared to uncoated alternatives. If you're running a full-length or neck-sizing press and want smoother operation with less wear on your dies and brass, this bushing delivers the performance.
Redding's bushing system lets you fine-tune neck tension by swapping in different sizes in .001-inch increments. The titanium nitride coating isn't just a cosmetic upgrade; it materially reduces the friction between case neck and bushing, which means easier lever pulls, less heat buildup, and more consistent sizing stroke-to-stroke. That matters when you're processing hundreds of rounds and trying to maintain uniformity.
This is the .331-inch size, so verify your cartridge's neck diameter before ordering. Redding bushings are industry standard in precision reloading—trusted by handloaders across rifle calibers. Whether you're prepping match ammo, hunting rounds, or volume rifle brass, a titanium nitride bushing is a smart upgrade from basic steel.

Frequently Asked Questions
What cartridges use a .331-inch neck bushing?
The .331-inch bushing is sized for cartridges with .331-inch neck diameters. Check your specific cartridge's reloading manual or SAAMI specs to confirm the correct bushing size before purchase.
How does titanium nitride coating improve reloading performance?
Titanium nitride increases surface hardness, which reduces friction between the case neck and the bushing during sizing. This means smoother lever operation, less wear on both the bushing and your die, and more consistent sizing pressure over many reloading cycles.
Can I adjust neck tension with this bushing?
Yes. Redding's bushing system is built on the principle of swappable sizes in .001-inch increments. By changing bushings, you can fine-tune how tightly the bushing sizes your case necks, which directly controls neck tension on your finished rounds.
Is this bushing compatible with all Redding dies?
Redding bushings are designed for Redding's bushing-style dies. Verify that your die is a bushing-compatible Redding model before ordering. Consult Redding's product specs or your die documentation for compatibility.
