Redding Titanium Nitride Bushing/.324

The Redding Titanium Nitride Bushing in .324" is a precision reloading die component built for handloaders who demand consistent neck sizing with minimal friction and wear. This bushing is coated with titanium nitride—a hard ceramic finish that reduces sizing resistance and extends tool life—making it ideal for high-volume reloaders and those working with premium brass who want to preserve case integrity over many reload cycles.

Redding's titanium nitride neck size bushings are engineered to work with Redding's bushing-style die systems. The .324" size covers a wide range of cartridges in that bore diameter range. Because the bushing does the actual sizing work rather than the die body itself, you can swap bushings to fine-tune fit for different brass lots or bullet diameters—a significant advantage over fixed dies when you're chasing tight concentricity or working with mixed brass.

The titanium nitride coating is the key upgrade here. It hardens the steel substrate and reduces the friction between case neck and bushing, which means easier press lever motion, less heat buildup, and less wear on both the bushing and your brass. Over hundreds of reloads, that translates to more consistent neck tension and longer bushing life before sizing characteristics drift.

Key Features

• Titanium nitride coating increases surface hardness and reduces sizing friction
• Precision .324" diameter for compatible cartridge specifications
• Swappable design allows fine-tuning of neck fit and tension
• Heat-treated steel base ensures durability under repeated use
• Reduces case neck wear compared to standard die sizing

Frequently Asked Questions

What cartridges use a .324" neck size bushing?

The .324" bushing is sized for cartridges with a .324" neck diameter. Consult your reloading manual or Redding's bushing size chart to confirm the correct bushing diameter for your specific cartridge.

Do I need a special die to use this bushing?

Yes, this bushing is designed to work with Redding's bushing-style neck size dies. The bushing inserts into the die body and performs the actual sizing work. Standard fixed-die systems do not use interchangeable bushings.

What's the advantage of titanium nitride over a standard bushing?

The titanium nitride coating hardens the surface, reducing friction between the case neck and bushing. This means easier sizing, less heat generation, less wear on your brass, and longer bushing life before sizing characteristics change.

Can I use this bushing with different brass and bullets?

Yes. Because the bushing is swappable, you can select or order different bushing sizes to fine-tune neck fit for different brass lots or bullet diameters, giving you precise control over neck tension.
