Bush - Redding Neck Size - 366 TiN

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 calibres 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 micrometre, then subtract .001" to allow for brass spring back and bullet tension.
