Neck tension is one of those details that separates good handloads from great ones, and the Redding .248 Titanium Nitride bushing gives you direct control over it. This is the .248 inch size from Redding's TiN bushing line, built to drop into any Redding Bushing-Style neck sizing die. The bushing starts as heat-treated steel, hand polished to a surface hardness around Rc 60-62, then gets a titanium nitride coating that pushes the effective surface hardness higher and cuts down the friction you feel on the downstroke. The result is smoother sizing and a bushing that holds its dimension over a long reloading life.
Instead of squeezing the whole case neck down and then pulling it back open with an expander, a bushing die sizes the neck to the exact diameter you choose. By picking the right bushing, you set just enough tension to hold the bullet firmly without overworking the brass. That means less work hardening, longer case life, and more uniform seating from round to round. The .248 fits the .248 outside neck diameter you're targeting, which falls into the 22 and 6mm caliber range depending on your brass and bullet combo.
All Redding neck sizing bushings share the same external dimensions, one half inch outside diameter by three eighths inch long, so they freely interchange across Redding bushing dies and also work with Wilson-style bushings. Every bushing is marked with its size for quick identification in your kit. To find the right number, measure the outside neck diameter of a loaded cartridge with a precision micrometer, then subtract about .001 to .002 inch to allow for brass spring-back and proper bullet grip.
These are made in the USA and sold as a single bushing, so it's easy to build a small range of sizes and fine-tune tension for different loads. Dies and shellholders are sold separately.
It drops into all Redding Bushing-Style neck sizing dies, including the Type S Full and Neck Sizing dies. Because it shares standard external dimensions, it also interchanges with Wilson-style bushings. The die itself and a shellholder are sold separately.
Measure the outside neck diameter of a loaded cartridge with a precision micrometer, then subtract about .001 to .002 inch. That subtraction accounts for brass spring-back and gives you proper bullet grip. If your measurement lands around .250, the .248 bushing is a common choice, but always verify with your own loaded rounds.
The TiN coating raises the effective surface hardness beyond the already hardened steel and adds lubricity, so the neck slides through with less friction on the downstroke. That means smoother sizing and a bushing that resists wear and holds its dimension over the long haul. Function-wise it sizes the same as a steel bushing, just slicker.
A bushing sizes only the neck to a diameter you select, so you set exact neck tension without overworking the brass. Standard dies squeeze the neck down and then pull it back open with an expander, which works the metal more and shortens case life. Bushing sizing gives you more consistent tension and longer-lasting cases.
