What size bushing for 257 Wby Mag? I see 300 Wby Mag listed. Expert Answer

Hornady does not specifically list the Bushing for 257 WBY Mag. However, this is what Hornady states, "Determining the proper bushing diameter: If you add the neck diameter and the shoulder diameter and divide that number by two, use the bushing closest to that number."

Box contained wrong comparator by Rob, Verified Owner, September 1, 2021
Brand new box contained duplicate dies, not the five different dies (.33 through .42) advertised. There is not purpose for a duplicate die, and I needed the .420 die for case headspace measurement of a 300. Much hassle for a very basic qc issue.

Product Info for Hornady Lock-N-Load Headspace Gauge With Five Bushings HK66

Hornady Lock-N-Load Headspace Gauge HK66 is an excellent way to compare your handloaded casings with their fire-formed brass counterparts. A great reloading tool for extending the life of your brass, the Headspace Gauge measures variations in your casing before and after firing, allowing you to adjust for the deformations that can occur under the extreme heat and pressure of a rifle discharge. This valuable piece of Hornady reloading equipment attaches to a pair of calipers using a thumbscrew and allows you to check most bottleneck casings. Hornady has included five bushings in the Hornady LNL Headspace Gauge, ranging from .330 to .420, so you can accurately assess all sorts of casings. To improve your casings' longevity, safety, and accuracy, compare and assess them using the Hornady Lock-N-Load Head Space Gauge.image
