Description
The Hornady Lock-N-Load Neck Wall Thickness Gauge is a precision reloading accessory designed to identify variations in case neck wall thickness during case preparation. Built around a .0005 increment dial indicator, this gauge lets the handloader sort and measure case necks with confidence, providing a clear, repeatable read on neck thickness variations that can affect bullet concentricity and overall accuracy.
Manufactured from stainless steel for long-term durability on the reloading bench, the gauge is designed to work directly with the Hornady Lock-N-Load Concentricity Tool (sold separately), giving reloaders a complete workflow for inspecting case necks before and after turning. Once a variation is identified, the gauge also pairs with the Hornady Lock-N-Load Neck Turning Tool (041224), sold separately, to correct neck thickness to a uniform spec.
Designed for the advanced handloader, the Neck Wall Thickness Gauge is ideal for sorting incoming brass, verifying the consistency of a neck turning operation, and dialing in match-grade ammo where uniform neck tension is critical. The compact, bench-friendly footprint integrates easily with an existing Hornady Lock-N-Load precision measuring setup.
