L.E. Wilson has been building precision reloading tools for generations, and this little .327 steel bushing is a big part of how serious handloaders fine-tune their ammo. It slides into a Wilson neck sizing die or Wilson bushing-type full-length die and sizes the outside of the case neck to the exact diameter you want, giving you control over neck tension that a traditional expander-ball setup just can't match. Each bushing is machined from polished and precision-ground steel, so it holds its dimension and shrugs off years of use on the bench.
The whole idea behind a bushing system is matching the bushing to your specific brass and bullet combo. The size stamped on the bushing refers to the middle, which is reamed with a slight taper. Because the case neck only reaches that middle section, you can flip the bushing over with the markings facing the case to get a touch tighter sizing when your brass has work-hardened or you're fine-tuning grip. That flexibility is a handy trick when you're chasing consistency in load development.
Sizing is simple once you know the formula. Measure the outside diameter of a loaded round right where the bullet sits in the neck, then subtract .002 to .003 inches. That leaves room for the brass to spring back and gives you roughly .001 to .002 of grip on the bullet. You can also measure neck wall thickness, multiply by two, add your bullet diameter, and subtract that same .002 to .003. Either method gets you to the right number, and the .327 covers one specific point in that range.
Wilson makes bushings in .001 inch increments, so you can cover just about any cartridge and keep correct neck tension across your brass. This bushing freely interchanges in all Wilson bushing-type neck sizing dies and is made to similar specs as Redding neck bushings, so it works in those dies too. Made in the U.S.A., it's a small investment that pays off in repeatable, consistent reloads.
It freely interchanges in all Wilson bushing-type neck sizing dies and Wilson bushing-type full-length sizing dies. Because it's made to similar specs as Redding neck bushings, it also works in Redding bushing dies. Note that it will not interchange with Forster dies.
Measure the outside diameter of a loaded round where the bullet sits in the neck, then subtract .002 to .003 inches. If that math lands you at .327, this is your bushing. You can also measure neck wall thickness, multiply by two, add bullet diameter, and subtract the same amount.
Yes. The size marked on the bushing refers to the middle, which is reamed with a .003 taper. Turning the bushing over so the markings face the case gives a slightly tighter size, which is useful for work-hardened brass or fine-tuning grip without jumping to the next smaller bushing.
A bushing-type die uses the bushing to size the outside of the case neck, so it eliminates the need for a conventional expander ball. That means less brass working, better concentricity, and longer case life. This approach is a favorite among precision reloaders chasing repeatable neck tension.
