The L.E. Wilson Steel Neck Sizer Die Bushing .333 is a hardened stainless steel neck bushing built for precision reloaders who demand consistency across their brass prep work. This .333-inch bushing is engineered to work with Wilson-compatible reloading dies and gives you control over how tightly your case necks grip your bullets—a detail that matters more the tighter your tolerances and the more rounds you're running through a given rifle.
Wilson manufactures these bushings in .001-inch increments, and the marked size refers to the bushing's middle section, which is reamed with a .003-inch taper. That taper design means you have options. Run the bushing normally (markings facing up) for standard sizing. If you need to fine-tune—say your brass has hardened and is springing back too much, or you want less squeeze on the bullet than the next smaller bushing would deliver—flip it over so the markings face the case. This is mainly a tactical adjustment for experienced reloaders working through brass hardness issues or dialing in neck tension to within tenths of a thousandth.
Made to specs comparable to Redding neck bushings, the L.E. Wilson .333 will not interchange with Forster or RCBS dies, so verify your press compatibility before ordering. Selection is straightforward: measure the outside neck diameter of a loaded round and subtract .002 to .003 inches (accounting for normal spring-back), or calculate from case wall thickness × 2 + bullet diameter, then subtract .002 to .003 inches. Either method gets you in the ballpark for proper neck tension.

Frequently Asked Questions
Will this bushing work with my Forster or RCBS reloading dies?
No. The L.E. Wilson Steel Neck Sizer Die Bushing .333 is designed for L.E. Wilson-compatible neck sizing dies and will not interchange with Forster or RCBS equipment.
How do I select the right bushing size for my brass?
Measure the outside neck diameter of a loaded cartridge and subtract .002 to .003 inches to allow for brass spring-back. Alternatively, measure your case neck wall thickness, multiply by two, add your bullet diameter, and subtract .002 to .003 inches.
Can I flip this bushing over to adjust sizing?
Yes. Running the bushing normally (markings facing up) provides standard sizing. Flipping it so the markings face the case delivers slightly tighter sizing. This is mainly used to handle hardened brass that springs back excessively or to fine-tune neck tension without switching to the next smaller bushing.
What is the .003-inch taper, and why does it matter?
The taper is built into the bushing's middle section, where the case neck contacts during sizing. It allows the bushing to work in two orientations and gives you flexibility in adjusting how much squeeze the neck places on your bullet.
