Description
This is the .263 diameter Titanium Nitride neck sizing bushing from Redding, part number 76263. If you're running a bushing style die and chasing tighter, more repeatable groups, this is the kind of small part that makes a real difference at the bench. It lets you control neck tension precisely instead of sizing the whole neck down and springing it back out, which is easier on your brass and better for concentricity.
What the .263 TiN Bushing Brings to the Bench
Redding starts with heat treated steel bushings that are hand polished to a surface hardness of Rc 60-62, then adds a Titanium Nitride surface treatment. That TiN coating bumps up the effective surface hardness even more and cuts down sizing friction, which means smoother strokes and less drag as the neck passes through. The gold colored finish is how you'll spot the TiN versions apart from the plain steel ones in your kit.
Fitment and Sizing for the .263 Bushing
The external dimensions are the industry standard 1/2 inch outside diameter by 3/8 inch long, so this bushing drops right into any Redding bushing style die, including the Type S neck and full length sizing dies, and it interchanges with L.E. Wilson style bushings too. Redding offers these in .001 inch increments across the full range, covering calibers from 17 up to 338, and every bushing is clearly marked with its size. To figure out the right size, measure the outside neck diameter of a loaded cartridge with a precision micrometer and subtract about .001 to .002 inch to allow for brass springback and proper bullet tension.
A Note on Getting the Most From It
Many precision loaders keep two or three bushings a thousandth apart on hand so they can fine tune tension as their brass changes over firings. A good neck lube helps the TiN surface do its job and keeps things running clean. Made in the USA, this is a buy once, use for years kind of component.

Frequently Asked Questions
What dies does the Redding .263 Titanium Nitride bushing fit?
It fits all Redding bushing style neck sizing dies, including the Type S neck and full length sizing dies. Because it uses the standard 1/2 inch outside diameter by 3/8 inch long dimensions, it also interchanges with L.E. Wilson style bushings. Bushings are sold separately from the dies, so this is the part you add to get your die working.
How do I know if the .263 is the right bushing size for my brass?
Measure the outside neck diameter of a loaded cartridge with a precision micrometer, then subtract about .001 to .002 inch to allow for brass springback and bullet tension. If that math lands you right around .263, this is your bushing. Many loaders keep a bushing or two on either side so they can fine tune neck tension as their brass changes.
What's the difference between the Titanium Nitride bushing and the plain steel version?
Both start as heat treated steel hand polished to Rc 60-62 hardness. The Titanium Nitride version adds a TiN surface treatment that increases effective surface hardness and reduces sizing friction, giving you smoother strokes. The TiN bushings are gold colored, which makes them easy to tell apart from the plain steel ones.
Do I still need neck lube with the TiN bushing?
Yes, a quality neck lube is still a good idea even with the slicker Titanium Nitride surface. It helps everything run smoothly, keeps sizing effort low, and protects your brass. A dry neck lube or application media works well with this type of bushing.
