Hornady Match Grade Neck Sizing Bushing .331in
The Hornady Match Grade Neck Sizing Bushing .331in is an interchangeable bushing designed for use with Hornady Match Grade Bushing Dies. It allows reloaders to adjust neck tension precisely by swapping bushings, enabling customization based on brass neck-wall thickness.
The .331in diameter is suitable for .30 caliber cartridges. The ideal size is determined by measuring fired brass and subtracting twice the wall thickness to achieve the desired neck tension.
Manufactured to tight tolerances, this bushing features a self-centering design that promotes concentricity during resizing, resulting in more consistent ammunition and tighter group shots at the range.

How do I determine the correct size for my brass?
Measure the fired brass neck wall thickness, then subtract twice that value from the original diameter to determine the appropriate bushing size for desired tension.
Does this bushing work with all Hornady dies?
Yes, it is specifically designed for use with Hornady Match Grade Bushing Dies.

Neil Davidson –
This bushing fits perfectly with my Hornady die set. I was able to fine-tune the neck tension based on my brass measurements, and my group sizes improved noticeably after switching from a fixed die setup.
Steven Hemmings –
Great precision tool for match-grade reloading. The self-centering design ensures consistent neck sizing, which translates to better accuracy in my shooting sessions.
Lillian Avery –
Works well with my .308 brass. I had to measure my fired cases to find the right tension, but once I did, the results were consistent and repeatable.
Kimberly Hamilton –
I swapped between different bushings to test tension levels. The die performs smoothly and maintains concentricity, which I can see in tighter groupings at the range.
