Description

A precision-machined .330″ diameter neck sizing bushing with a gold Titanium Nitride (TiN) coating. This bushing provides a high-hardness, low-friction surface that ensures smooth resizing and consistent neck tension while extending the life of your brass.

The 76330 bushing represents the high-water mark for neck-sizing technology. The base is constructed from heat-treated steel, which is then coated with Titanium Nitride (TiN). This coating significantly increases the surface hardness and provides a “slick” interface, allowing the case neck to glide through the bushing with minimal resistance. This reduction in friction is vital for maintaining case concentricity and preventing the neck from stretching or “pulling” during the sizing stroke.

The .330″ diameter is a specialized size in the .308 Winchester and .30-06 family. It is most commonly used by shooters who have neck-turned their brass to a thinner dimension for match-grade consistency, or those using specific brands of brass with thin walls (approx. .011″ – .012″) who need to ensure the bullet is held securely.
