The Hornady .366" Match Grade Bushing is the small part that makes a big difference when you're chasing consistency. It's a self-centering neck sizing bushing that fits Hornady Match Grade bushing dies, letting you set exactly how much the case neck gets squeezed down during resizing. That control over neck tension is one of the biggest factors in how well your reloads group, which is why handloaders who care about repeatability lean on bushing setups like this one.
At .366" in diameter, this bushing sits at the larger end of Hornady's lineup and is a common pick for .338 caliber cartridges. Hornady offers these in .001" increments, so you can fine-tune the fit to your specific brass and the neck tension you want. Different brands and lots of brass vary in neck wall thickness, so the "right" bushing depends on your components. A reliable way to land on the correct size is to measure the neck diameter of a loaded round and subtract the amount of tension you're after, usually somewhere around .002" to .004".
Because the bushing sizes the neck from the outside, it only works the brass as much as needed and no more. The self-centering design helps keep everything concentric, which cuts down on runout and keeps your case necks from getting overworked over repeated firings. Less overworking means brass that lasts longer and behaves more predictably load after load.
This bushing is a component, not a complete die, so it's meant to drop into a Hornady Match Grade bushing die you already own or plan to buy. Swapping bushings is quick thanks to the knurled spindle lock on those dies, so once you've found the sizes that work for your rifle and brass, changing between them takes seconds. A lot of precision reloaders end up keeping several bushings on hand to account for different brass and tension preferences, and this .366" is a solid addition for anyone running .338 cal.
This bushing is most commonly used with .338 caliber cartridges, since it sits at the larger end of Hornady's bushing range. The exact bushing you need still depends on your brass and the neck tension you want. Measuring a loaded round is the best way to confirm .366" is right for your setup.
Measure the neck diameter of a loaded or dummy cartridge with a good micrometer, then subtract the amount of neck tension you want, typically around .002" to .004". That number gets you to the bushing diameter. Since brass brands and lots vary in neck wall thickness, many reloaders buy a couple of sizes to test and settle on the one that shoots best.
No, it's designed specifically for Hornady Match Grade bushing dies. It's a component rather than a complete die, so you'll need the matching die for it to drop into. The knurled spindle lock on those dies makes swapping bushings quick and easy.
A bushing sizes the neck from the outside and only works the brass as much as needed, which helps avoid overworking and oversizing the case necks. The self-centering design keeps things concentric to reduce runout. The result is more consistent neck tension and brass that holds up better over repeated firings.
