Description
If you're running a Redding bushing-style neck or full-length sizing die, this .247 Titanium Nitride bushing lets you take real control over how much your case necks get worked. Instead of squeezing the neck way down and forcing the expander ball to pull it back out, a bushing sizes the neck to one precise diameter so you set exactly the neck tension your load likes. This one measures .247 inches, which is a popular size for calibers like the .223 Remington depending on your brass and bullet combo.
How the .247 TiN Bushing Earns Its Keep
Redding builds these from heat-treated steel and hand polishes the sizing surface to a hardness of Rc 60-62 to keep the sizing stroke smooth. The Titanium Nitride coating is what sets this version apart from the plain steel bushings. That gold-colored TiN surface bumps the hardness even higher and cuts down on friction, so the neck slides through easier and you get less drag on the brass. A lot of reloaders also find the TiN finish is more forgiving when it comes to how much neck lube they use.
Picking the Right Redding Bushing Size
Getting the size right is the whole ballgame. Measure the outside neck diameter of a loaded cartridge with a good micrometer, then subtract .001 to .002 inches to account for brass spring-back and the grip needed to hold the bullet. That number is your bushing size. Every bushing is clearly stamped with its size I.D. so there's no guesswork once you've got it in hand, and Redding offers them in .001 inch increments covering everything from .17 up through .338.
These bushings share standard external dimensions of 1/2 inch O.D. by 3/8 inch long, so they drop right into any Redding bushing-style sizing die and swap out freely when you move between loads or calibers. Made in the USA, this is a small part that makes a real difference in how consistent your ammo turns out.

Frequently Asked Questions
How do I know if the .247 bushing is the right size for my brass?
Measure the outside neck diameter of a loaded round using a precision micrometer, then subtract .001 to .002 inches to allow for brass spring-back and proper bullet grip. The result is your ideal bushing size. The .247 is commonly used for .223 Remington loads, but your exact number depends on your brass thickness and bullet, so always measure your own loaded ammo.
What's the difference between the Titanium Nitride bushing and the steel version?
Both start as the same heat-treated, hand-polished steel bushing with a surface hardness of Rc 60-62. The Titanium Nitride version adds a TiN coating that increases the surface hardness even further and reduces sizing friction. That gold-colored finish makes the sizing stroke smoother and is often easier on neck lube requirements.
Will this bushing fit my Redding die?
Yes. Redding neck sizer bushings use standard external dimensions of 1/2 inch O.D. by 3/8 inch long and freely interchange in all Redding bushing-style sizing dies. You can swap bushings in and out as you change loads or calibers without any extra parts.
Why use a bushing die instead of a standard full-length sizer?
A bushing lets you size the case neck to one precise diameter so you set exactly the neck tension you want. This avoids overworking the brass by squeezing it down too far and then dragging it back open with an expander ball. The result is more consistent neck tension, which usually translates to better accuracy and longer brass life.
