Description
The Redding .290″ Titanium Nitride Neck Sizing Bushing (item 76290) sets the neck diameter in any Redding bushing-style die — Type S Bushing Neck and Full Length dies, Type S Match and Elite sets and the Competition Bushing Neck die. Redding machines the bushing from heat-treated steel and applies a Titanium Nitride surface treatment that lifts the effective surface hardness and cuts sizing friction; the sizing bore is hand-polished to Rc 60-62. The standard bushing measures 1/2″ outside diameter by 3/8″ long and is marked with its size. Choosing the bushing by measuring the neck of a loaded round and subtracting 0.001″-0.002″ gives Australian precision and F-Class reloaders exact, repeatable neck tension without an expander ball.

Frequently asked questions
Which bushing size do I need?
Measure the neck diameter of a loaded or dummy round with a micrometer and subtract 0.001″-0.002″ for the bushing size. Redding publishes a master bushing table if you cannot measure a loaded round.
Does it fit non-Redding dies?
Redding bushings are the common 1/2″ x 3/8″ pattern; many other brands’ bushing dies accept them, but check your die maker’s specification.
Do I need to lube the case neck?
No. The Titanium Nitride surface is designed to size without neck lubrication.
