Description
The Redding .327 Titanium Nitride Bushing is the small part that makes a big difference when you're chasing tighter groups and better consistency. It's built from heat-treated steel and finished with a titanium nitride surface treatment that pushes the effective surface hardness up around Rc 85. That harder, slicker face means less drag as the neck passes through, which translates to smoother sizing and bushings that hold their dimension over a long reloading life.
What the .327 TiN Bushing Does for Your Loads
Bushing-style sizing is all about control. Instead of relying on an expander ball to set neck tension, you pick the exact bushing diameter that gives you the grip you want on the bullet. The bushing floats and self-centers on the case neck, which helps keep runout down and concentricity up. For folks running precision rifle, benchrest, or carefully worked-up hunting loads, that control over neck tension is a real contributor to lower ES and more repeatable accuracy. It also lets you adjust on the fly when you switch brass brands or lots that measure a little different in neck thickness.
Picking the Right Redding Titanium Nitride Bushing Size
Getting the size right matters more than anything. The easiest method is to measure the loaded neck diameter of a few rounds with a good micrometer, then subtract about .001 to .002 inch to allow for brass spring-back and leave a proper press fit on the bullet. That .002 figure gives firmer tension, while .001 runs a bit lighter, so a lot of handloaders keep a couple of neighboring sizes on hand to fine-tune. Redding offers these in .001 inch increments across the full range, so you can land right where you want.
Fitment and Build
This .327 bushing drops into Redding's Type S Full Length and Neck Sizing dies, and it also interchanges with L.E. Wilson style bushings used by RCBS, Hornady, and other brands that accept that pattern. It's made in the USA, and Redding's reputation with precision reloaders is well earned. Lubrication is recommended for the smoothest results.

Frequently Asked Questions
What dies does the Redding .327 titanium nitride bushing fit?
It fits all Redding Type S Full Length and Neck Sizing dies that use the bushing system. It also interchanges with L.E. Wilson style bushings, so it works in bushing dies from RCBS, Hornady, and other brands that accept that pattern.
How do I know if .327 is the right bushing size for my brass?
Measure the outside neck diameter of several loaded or dummy cartridges with a precision micrometer, then subtract about .001 to .002 inch to account for brass spring-back. The .327 bushing is the right call when that math lands you here. Many handloaders keep a neighboring size or two on hand to fine-tune neck tension.
What does the titanium nitride coating actually do?
The TiN surface treatment raises the effective hardness of the sizing surface to around Rc 85 and reduces friction as the neck passes through. That means smoother, more consistent sizing and a bushing that holds its dimension over a long reloading life. It's a step up in durability over plain heat-treated steel bushings.
Do I need to lubricate the neck when using this bushing?
Yes, light lubrication is recommended for the smoothest operation and most consistent results. A little neck lube helps the case glide through the bushing and reduces wear over time. It also makes the sizing stroke feel noticeably smoother on the press.
