Redding 73 Style Steel Neck Bushing .338 – 73338 Sizing Bushing

Description

This is the .338 diameter steel neck sizing bushing from Redding's 73 series, part number 73338. If you run a bushing style neck sizing die, this little piece is how you take real control over your neck tension instead of settling for whatever a standard full length die gives you. It measures the industry standard 1/2 inch outside diameter by 3/8 inch long, so it drops straight into any Redding bushing style sizing die without fuss.

The idea behind these is simple but it makes a noticeable difference at the bench. By picking the right bushing size, you size the neck down just enough to grip the bullet properly without overworking the brass. That means less runout, more consistent bullet seating, and brass that lasts longer because you are not stretching and springing it back further than it needs to go. For precision loads and long range work with a .338, that kind of repeatability is what separates a good group from a great one.

What Makes the Redding 73338 Steel Bushing Worth It

These are heat treated steel bushings with the sizing diameter hand polished to a surface hardness of Rc 60-62. That hardness and polish cut down the effort it takes to run a case neck through, and the surface holds up to a lot of cycles. Every bushing is clearly marked with its size, so there is no guessing which one you grabbed out of the box. They are made in the USA, which is the kind of quality control you want on a tool that touches every round you build.

Picking the Right .338 Bushing Size

To find your number, measure the outside neck diameter of a loaded cartridge with a good micrometer, then subtract about .001 to .002 inches to account for brass springback and the tension you want on the bullet. The Redding bushings come in .001 inch increments across the full range, so you can fine tune to your exact brass and chamber. If you are running tight necks or chasing a specific tension, it is worth keeping a couple of sizes on hand to test.
