The L.E. Wilson Steel Neck Sizer Die Bushing .332 is a precision reloading component built for handloaders who demand repeatable neck tension and tight ammunition tolerances. This hardened stainless steel bushing works with L.E. Wilson neck-sizing dies to control how much the case neck grips your bullet—critical for consistent velocity, accuracy, and brass longevity. If you're loading for precision rifle, benchrest, or hunting applications where every tenth of a grain and every thousandth of an inch matter, a properly sized neck bushing is one of the easiest ways to improve your ammunition quality without starting over.
L.E. Wilson manufactures these bushings in .001" increments, and the marked diameter refers to the middle of the bushing, which is reamed with a .003" taper. That taper design means you have tuning options: use the bushing normally (markings facing up), or flip it over to achieve a slightly tighter sizing action—handy if your brass has hardened and is springing back excessively, or when you're fine-tuning neck tension to reduce squeeze pressure compared to the next smaller bushing size. This flexibility lets experienced reloaders dial in the exact feel and performance their specific loads demand without buying multiple dies.
Construction matches the quality of Redding neck bushings, but Wilson bushings are not compatible with Forster or RCBS die systems—verify your die brand before ordering. Sizing your neck correctly extends brass life and reduces flyers; a quick measurement of your loaded cartridge neck diameter, minus .002" to .003" for proper spring-back, gives you the bushing size you need. Whether you're loading 20 rounds for a new rifle or maintaining a full reloading bench, this .332 bushing is a precise, durable tool for the serious handloader.

Frequently Asked Questions
What die systems are compatible with L.E. Wilson neck bushings?
L.E. Wilson neck bushings work only with L.E. Wilson neck-sizing dies. They will not interchange with Forster or RCBS dies, so confirm your die brand before purchasing.
How do I choose the right bushing size for my ammunition?
Measure the outside neck diameter of a loaded cartridge and subtract .002" to .003" to account for brass spring-back and correct neck tension. Alternatively, measure your case neck wall thickness, multiply by two, add your bullet diameter, and subtract .002" to .003". The .332" marking on this bushing refers to the middle diameter, which is where the case neck seats during sizing.
Can I flip the bushing over for tighter sizing?
Yes. Turning the bushing over so the markings face toward the case (down) achieves a slightly tighter sizing action. This is useful for fine-tuning neck tension on hardened brass or when you need less squeeze than the next smaller bushing would provide.
Why would I flip the bushing instead of buying the next smaller size?
Flipping allows incremental adjustment without committing to a full .001" jump in bushing diameter. It's a practical solution if your brass has hardened and is springing back more than expected, or when you're experimenting with the exact neck tension your load prefers.
