Hornady .366 Match Grade Bushing

The Hornady .366 Match Grade Bushing (Hornady part no. 594366) is an interchangeable neck-sizing bushing that drops into Hornady’s bushing-style full-length and neck dies to control exactly how much neck tension a resized case holds on the bullet. Made by Hornady, each bushing is ground to a single precision diameter, so handloaders can dial in neck tension in small, repeatable steps instead of being locked to whatever a fixed die neck happens to produce. Precision and long-range shooters who chase tight, consistent groups swap bushings to match a specific rifle and load rather than relying on a one-size-fits-all neck section. It’s a small, inexpensive upgrade that pays off in more consistent bullet pull and better round-to-round accuracy.

Key Specifications

• .366 inch is the precision-ground outside diameter of this bushing.
• Interchangeable fit: drops into any Hornady bushing-style full-length or neck die without tools.
• Neck-tension control: choosing a bushing 0.001 to 0.004 inch under loaded neck diameter sets consistent bullet pull.
• Hardened steel construction resists wear from repeated sizing strokes.
• Diameter is marked on the bushing for fast identification when swapping sizes on the bench.

Frequently Asked Questions

What does a neck-sizing bushing do? It’s the interchangeable sizing surface inside a bushing-style die, letting you set the exact neck diameter (and therefore bullet tension) for a specific case and load.

How do I pick the right bushing size? Measure the neck outside diameter of a loaded round, then choose a bushing roughly 0.001 to 0.004 inch smaller than that measurement for typical neck tension.
