Redding Titanium Nitride Bushing/.330
The Redding Titanium Nitride Bushing/.330 is a precision reloading die component engineered to give you tighter, more consistent neck sizing on your rifle cartridges. Built from heat-treated steel and finished with a titanium nitride coating, this bushing reduces sizing friction and boosts surface hardness—meaning smoother operation, longer service life, and repeatably precise results at the reloading bench.
Redding's bushing system lets you fine-tune neck fit to your specific brass and rifle, improving concentricity and case longevity compared to fixed-die sizing. The .330" diameter bushing works with Redding's bushing neck-sizing dies to give you the control serious reloaders demand. Whether you're loading for precision rifle competition, hunting, or long-range shooting, a quality bushing matched to your brass dimensions is one of the highest-value upgrades you can make to your reloading setup.
The titanium nitride surface treatment isn't just about durability—it also reduces the amount of sizing compound needed, keeps the bushing cleaner during the reloading cycle, and resists the micro-wear that can gradually enlarge neck fit over thousands of rounds. This is the kind of detail that separates careful handloading from casual reloading.

Frequently Asked Questions
What is a neck sizing bushing and why do I need one?
A neck sizing bushing is a wear surface that precisely sizes only the neck of your brass, leaving the body and shoulder untouched. This reduces case work, extends brass life, and improves concentricity compared to full-length sizing. Bushings come in .001" increments, so you can match your specific brass dimensions for a custom fit.
Will this .330" bushing work with my Redding die set?
This bushing is designed to work with Redding bushing neck-sizing dies. Confirm your die model accepts interchangeable bushings before ordering. The bushing simply screws into the die body.
Why choose titanium nitride over standard steel bushings?
The titanium nitride coating increases surface hardness and reduces friction compared to uncoated bushings. This means smoother sizing cycles, less lubrication needed, less wear buildup over time, and longer overall bushing life—making it a smart investment for high-volume reloaders.
