The Redding .246" Neck Sizing Bushing is the sizing ring that determines the diameter to which the case neck is reduced, and consequently the tension with which the neck holds the bullet. This version is made of steel treated with a titanium nitride surface coating.
The titanium nitride coating increases surface hardness and reduces friction compared to bare steel: neck sizing requires less effort and the working surface remains stable over time. The bushing works only on the neck, without touching the body and shoulder of the case, and can be replaced in seconds to change bullet tension: the Redding range covers diameters in .001" increments, from .185" to .368", corresponding to calibers from .17 to .338.

Recommended use
It fits all Redding Bushing Style dies and is interchangeable with Wilson-type bushings. To choose the diameter, Redding suggests using a micrometer to measure the outside diameter of the neck of a loaded cartridge and subtracting .002", a value that accounts for the springback of the brass. The manufacturer recommends lubricating the neck before resizing.
