Redding .291" heat-treated steel neck sizing bushing

Redding .291" Heat-Treated Steel Neck Sizing Bushing

The Redding .291" Neck Sizing Bushing is the sizing ring that determines the diameter to which the case neck is reduced, and therefore the tension with which the neck holds the bullet. This version is made of heat-treated steel.

The steel is treated to a surface hardness of approximately Rc 60-62, and the sizing diameter is hand-polished, a process by which Redding reduces the effort required to pass the neck through. The bushing works only on the neck, without touching the body or 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 mounts in all Redding Bushing Style dies and is interchangeable with Wilson-type bushings. To choose the diameter, Redding suggests measuring the outside diameter of the neck of a loaded cartridge with a micrometer and subtracting .002", a value that accounts for the springback of the brass. The manufacturer recommends lubricating the neck before sizing.
