Description
This is Redding's .286 diameter neck sizing bushing in their Titanium Nitride finish, part number 76286. If you're running a Redding bushing-style neck sizing die or a Type S setup, this is the piece that lets you fine tune how tightly your case necks grip the bullet. Instead of sizing the neck all the way down and then expanding it back out, a bushing sizes it to the exact diameter you choose, which means less working of the brass and more consistent results across a batch.
What the .286 Bushing Actually Does
Neck tension is one of those details that separates plinking loads from ammo that prints tight groups. By picking the right bushing size, you set just enough grip to hold the bullet securely without over sizing and fatiguing the brass. The way to figure your size is to measure the outside neck diameter of a loaded round with a good micrometer, then subtract about .001 to .002 inches to account for brass spring back. Land on .286 and this is your bushing.
Why Go Titanium Nitride on the 76286
Redding offers these bushings in both heat treated steel and this Titanium Nitride version. Both are machined to the same external dimensions, 1/2 inch outside diameter by 3/8 inch long, and both carry a hardened surface in the Rc 60 to 62 range. The TiN coating on this one adds extra surface hardness and cuts down on sizing friction, so the neck slides through smoother and the bushing tends to leave cleaner necks when the brass is lubed. For folks loading a lot of rounds or chasing that last bit of consistency, the slicker finish is a nice upgrade.
Fit and Compatibility
These freely interchange in all Redding bushing style neck sizing dies, and they also work with L.E. Wilson style bushings and most other popular brands that use the same format. The size is clearly marked right on the bushing, so once you've got a few in your kit you can swap them in seconds to match different cartridges or chase a different neck tension. Made in the USA.

Frequently Asked Questions
How do I know if the .286 bushing is the right size for my load?
Measure the outside neck diameter of a loaded round with a precision micrometer, then subtract about .001 to .002 inches to allow for brass spring back. If that math lands you near .286, this is your bushing. Measuring a few loaded rounds and averaging gives you the most reliable number.
What's the difference between the Titanium Nitride bushing and the steel version?
Both are made from the same heat treated steel and share identical external dimensions, so they interchange the same way. The Titanium Nitride version adds a TiN coating that increases surface hardness and reduces sizing friction. That slicker finish helps brass slide through easier and tends to leave cleaner necks when the case is lubed.
Will the 76286 bushing fit my Redding Type S die?
Yes. These bushings freely interchange in all Redding bushing style neck sizing dies, including the Type S line. They also work with L.E. Wilson style bushings and most other popular die brands that use the same bushing format.
Why use a bushing die instead of a standard neck sizer?
A bushing sizes the neck to the exact diameter you choose rather than oversizing and then expanding back out. That means less working of the brass, more consistent neck tension, and generally longer case life. Swapping bushings also lets you fine tune neck tension to find what your rifle shoots best.
