If you're chasing tighter groups off the bench, neck tension is one of those details that quietly makes or breaks a load. This L.E. Wilson steel neck sizing bushing is marked .324 (part number B-324) and gives you a simple, repeatable way to size your case necks to exactly the grip you're after. Each bushing is precision ground from hardened steel, which is what lets Wilson hold tight tolerances and keep that sizing consistent round after round.
The bushing drops into a compatible bushing-style die and sizes the neck down to grip the bullet, no expander ball needed. Because you pick the exact bushing diameter, you control how much the neck gets worked. That means less brass movement, longer case life, and the kind of uniform neck tension that shows up on paper. A good rule of thumb is to measure the outside neck diameter of a loaded round and subtract roughly .002 to .003 of an inch to land on your starting bushing size. Different brass has different wall thickness, so it's worth measuring your own cases rather than guessing.
Wilson makes these in .001 inch increments, and this one covers the .324 slot. It interchanges freely across Wilson bushing-type neck sizing and full length dies, and it will also work in Redding, Hornady, and RCBS bushing dies. It will not fit Forster dies. Keep in mind these are steel bushings, so a light pass of case lube on the neck helps everything run smooth.
For anyone loading precision rifle rounds and wanting more control than a standard sizing die offers, having the right bushing on hand is the difference between hoping for consistency and building it in. Pick up the diameter that matches your brass and bullet combo and you're set.
Measure the outside neck diameter of a loaded cartridge with a good caliper or micrometer, then subtract about .002 to .003 of an inch for your starting bushing. You can also measure your neck wall thickness, double it, and add the bullet diameter, then subtract .002 to .003. Since brass wall thickness varies by brand, measure your own cases for the best fit.
It interchanges freely across L.E. Wilson bushing-type neck sizing and full length dies. It also fits Redding, Hornady, and RCBS bushing dies since they share similar specs. It will not work in Forster dies.
Yes. These are steel bushings, so a light coat of case lube on the neck helps them size smoothly and keeps the brass moving without drag. It also makes for more consistent results and easier operation at the press.
It can. Bushing-style neck sizing lets you set neck tension directly by picking the right bushing diameter, so you skip the expander ball and the extra working of the brass that comes with it. That approach helps extend case life and keeps neck tension more uniform.
