Precision reloading comes down to control, and few tools give you more of it than a quality neck sizing bushing. This Redding bushing measures .331 inches and lets you set the precise amount of neck tension your loads call for, holding the bullet firmly without overworking the brass. It's cut from heat-treated steel and finished with a Titanium Nitride (TiN) surface treatment that boosts surface hardness and reduces friction as the case neck passes through, so sizing feels smoother and brass life stays long.
Instead of a one-size-fits-all neck die, the bushing system lets you fine-tune. By choosing the right diameter, you get just enough tension to keep the bullet seated properly while avoiding the excessive resizing that fatigues case necks over time. A common way to find your size is to measure the outside neck diameter of a loaded round with a micrometer, then subtract about .001 to .002 inches to account for brass spring-back and bullet grip. This particular bushing lands at .331 inches and is clearly marked with its size for quick identification on the bench.
Redding neck sizing bushings all share the same external dimensions, a 1/2-inch outside diameter and 3/8-inch length, so they interchange freely across all Redding bushing-style neck sizing dies, including the Type S line. The lineup runs in .001-inch increments through a wide diameter range, covering calibers from .17 all the way to .338, which makes it easy to keep a small set on hand and tune different loads from the same die body.
If you're chasing tighter groups and better consistency on precision rifle rounds, swapping to the exact bushing your brass and bullets like is one of the simpler upgrades you can make. Made in the USA, this bushing is a straightforward addition to any serious handloading setup.
It fits all Redding bushing-style neck sizing dies, including the Type S Full Length and Type S Neck Sizing dies. Every Redding bushing shares the same 1/2-inch outside diameter and 3/8-inch length, so they interchange freely within that die system. The die itself is sold separately.
Measure the outside neck diameter of a loaded cartridge using a precision micrometer, then subtract about .001 to .002 inches to allow for brass spring-back and bullet tension. That number points you to the bushing diameter you need. Since Redding offers these in .001-inch increments, many handloaders keep two or three nearby sizes on hand to fine-tune.
The TiN surface treatment increases the effective surface hardness and reduces friction as the case neck slides through the bushing. That means smoother sizing and less drag, which is easier on your brass over repeated loadings. Both the steel and TiN versions share the same dimensions and fit the same dies.
Yes. Matching the bushing to your exact brass and bullet combination lets you set uniform neck tension without overworking the case necks, which supports more consistent bullet release and better groups. It's one of the most straightforward ways to tighten up load consistency on a bushing die setup.
