Description
The L.E. Wilson .292 Neck Sizer Die Bushing is the small part that makes a big difference at the reloading bench. This steel bushing sizes the outside of your case neck to a .292 finished diameter, giving you precise control over how tightly the neck grips the bullet. It's a drop-in insert, so it works with Wilson neck sizing dies as well as Wilson bushing-type full-length sizing dies, and it swaps out in seconds when you want to change tension or move to a different brass lot.
The whole point of running a bushing like this is to skip the one-size-fits-all expander ball. By sizing the neck from the outside only, you work the brass less, keep your necks more concentric, and extend case life while holding steady bullet seating. That's why precision and benchrest handloaders lean on these so heavily. L.E. Wilson has been building reloading tools since 1927, and these bushings are made in the U.S.A. to tight tolerances, machined from polished and precision-ground steel so they hold their dimension through plenty of sizing cycles. Since it's a steel bushing, a light coat of case lube on the necks keeps things smooth.
Picking the Right .292 Bushing for Your Load
Getting the size right is the key to this whole system. The common method is to measure the outside diameter of a loaded round at the neck, then subtract .002 to .003 inch. Brass springs back a touch after sizing, so that math usually lands you around .001 to .002 inch of grip on the bullet. You can also work it from neck wall thickness: double the wall thickness, add bullet diameter, then subtract .002 to .003. Many handloaders keep a few sizes on hand to tune tension for different bullets and brass.
Where the .292 Neck Bushing Fits
Wilson bushings are known to interchange across Wilson, Redding, Hornady, and RCBS bushing-style dies, so this isn't locked to one brand of die body. The number stamped on the bushing refers to the finished neck diameter, and flipping it so the markings face the case can net a slightly tighter size thanks to the internal taper. It's a simple, repeatable way to take control of one of the most important variables in accurate handloading.

Frequently Asked Questions
What does the .292 on this Wilson bushing mean?
The number refers to the finished outside diameter the bushing sizes your case neck down to, in this case .292 inch. Wilson makes these in .001 inch increments so you can land on the exact neck tension you want. The stamped size reflects the middle of the bushing, which is reamed with a slight taper.
How do I know if the .292 is the right size for my cartridge?
Measure the outside diameter of a loaded round at the neck where the bullet sits, then subtract .002 to .003 inch to account for brass spring-back. That typically leaves you with about .001 to .002 inch of grip on the bullet. You can also calculate it by doubling your neck wall thickness, adding bullet diameter, then subtracting .002 to .003.
Will this bushing work in dies other than L.E. Wilson?
Yes. Wilson neck bushings are known to interchange across Wilson, Redding, Hornady, and RCBS bushing-style dies. They do not fit Forster dies.
Does the .292 neck sizer bushing replace the expander ball?
That's the idea behind the bushing system. Sizing the neck from the outside lets you skip the conventional expander ball, which works the brass less, improves neck concentricity, and helps extend case life. It's a favorite approach among precision and benchrest handloaders.
