Redding Titanium Nitride Neck Bushings are a hand polished heat treated steel insert which have an additional Titanium Nitride surface treatment to further increase hardness and reduce friction when neck sizing.

The Titanium Nitride Bushings have an external diameter of 12.7mm OD x 9.525mm long (1/2" O.D. x 3/8" long) and freely interchange in all Redding Bushing style Neck Sizing Dies. Redding Neck Bushings are available in .001" size increments from .185" through to .368" covering all calibers from .17 to .338 and clearly marked with size I.D.

By selecting the correct bushing, you are now able to provide just the right amount of neck tension to properly hold the bullet without excessive resizing. To determine proper Bushing size, measure the outside neck diameter of a loaded cartridge with a precision micrometer, then subtract .001" to allow for brass spring back and bullet tension.

Determining Redding Bushing Size
The proper bushing size can be easily determined by measuring the outside neck diameter of your loaded cartridges with a precision micrometer or a dial caliper. Then, simply subtract .001" from the cartridge that had the smallest average neck diameter. This diameter bushing will generally size case necks just enough to create the proper press fit for the bullet.

If you are using a Type “S” style die and not turning the outside of your case necks, we suggest using a bushing .002" smaller than your smallest average neck diameter, and using the expander ball included with your Type “S” die. This size bushing will still give you minimal sizing (maximizing the life of your brass) and the expander ball will insure that each cartridge has the same bullet grip.

Redding has found that when you have cases with neck wall thicknesses on the thin side of the SAAMI tolerance, your fired case will measure considerably larger (.006" to .010" larger) than your loaded rounds. In these circumstances, Redding’s tests have shown that a bushing .001" larger (than the loaded round) may give you the desired bullet grip.
