Redding .304 Titanium Nitride Neck Sizing Bushing (76304)

Description

This is Redding's .304 diameter neck sizing bushing, built from heat treated hardened steel and finished with a titanium nitride (TiN) coating. That coating is the whole point here. It bumps up the surface hardness and slicks up the inside of the bushing so your case necks pass through with less drag than a plain steel bushing. For precision handloaders chasing consistency, that smoother feel translates to more uniform neck tension and brass that lasts longer.

The idea behind bushing style sizing is simple. Instead of squeezing the neck way down and then dragging an expander ball back through it, you pick a bushing that sizes the neck just enough to grip the bullet. Less working of the brass means less runout, less case stretch, and longer case life. Redding offers these in .001 inch increments covering calibers from 17 all the way up to 338, so you can match the bushing to your exact chamber and load.

How the .304 Redding TiN Bushing Fits Your Setup

The bushing measures 1/2 inch outside diameter by 3/8 inch long, and it drops right into any Redding bushing style neck sizing or full length die. The dimensions are standard across the lineup, so these interchange freely and also work in most other popular brands of dies built for this format. Every bushing is clearly marked with its size, which makes swapping between loads quick and foolproof.

Picking the Right Size Bushing

Sizing selection is straightforward. Measure the outside neck diameter of a loaded round with a good micrometer, then subtract .001 to .002 inches to account for brass spring back and the grip you want on the bullet. The .304 covers a common range for several 7mm and 30 caliber necks depending on your brass and loaded neck diameter. If you reload for accuracy and want full control over neck tension, a quality bushing like this is one of the small details that adds up at the target. Made in the USA.
