Description
Neck tension is one of those little details that separates loads that just go bang from loads that print tight groups, and this is where Redding's bushing system earns its keep. The .332" Titanium Nitride bushing lets you set the exact amount of grip on the bullet so it sits secure without working the brass harder than it needs. Less overworking means brass that lasts longer and necks that stay more consistent round after round.
What the TiN Coating Brings to the Table
This bushing starts as heat-treated steel, then the sizing surfaces are hand-polished to a hardness of Rc 60-62. From there, the titanium nitride treatment bumps up the surface hardness even further and cuts down on friction as the neck passes through. In plain terms, sizing feels smoother on the press handle and the bushing holds its dimensions over a long working life. It shares the same external dimensions as the standard steel bushings, so the gold-colored TiN finish is the easy way to tell them apart on the bench.
Fitment and Picking the Right Size
With a 1/2" outside diameter and 3/8" length, the Redding .332" bushing freely interchanges across all Redding bushing-style sizing dies and works with L.E. Wilson-pattern bushings too. Redding offers these in .001" increments covering calibers from 17 all the way up to 338, so you can fine-tune tension rather than settle for whatever a standard die gives you.
To land on the correct bushing, measure the outside neck diameter of a loaded or dummy cartridge with a precision micrometer, then subtract .001" to .002" to account for brass spring-back and proper bullet grip. If your neck wall thickness varies more than a couple thousandths, going a touch smaller and finishing with a sizing button is the move. Keep in mind this is the bushing only, so you'll need a compatible bushing-style die to run it.

Frequently Asked Questions
Will this .332" bushing fit my Redding die?
Yes, it shares standard external dimensions of 1/2" O.D. by 3/8" long and freely interchanges in all Redding bushing-style sizing dies. It also works with L.E. Wilson-pattern bushings. Just remember the die itself is not included, so you'll need a compatible bushing-style die to use it.
How do I know if .332" is the right bushing size for my cartridge?
Measure the outside neck diameter of a loaded or dummy round with a precision micrometer, then subtract .001" to .002" to allow for brass spring-back and proper bullet tension. If your neck wall thickness varies more than about .002", you may want to go a couple thousandths smaller and finish with a sizing button. The goal is firm bullet grip without overworking the neck.
What's the advantage of the titanium nitride version over the plain steel bushing?
The TiN-coated bushing offers the same core function as the standard heat-treated steel version but adds a titanium nitride surface treatment. That coating increases surface hardness and reduces friction during sizing, so the press stroke feels smoother and the bushing holds its dimensions over a long working life. The gold color also makes it easy to spot in a drawer full of bushings.
Does using a bushing really help brass life?
It can make a real difference. By choosing a bushing that sizes the neck only as much as needed, you avoid the over-sizing and re-expanding that standard dies often do, which work-hardens the brass faster. Less working of the neck generally means more consistent neck tension and more reloads out of each case.
