Hornady Lock-N-Load A Series Modified Case 7.62x39mm Brass

The Hornady Lock-N-Load A Series Modified Case is a precision reloading accessory designed for use with Hornady's Lock-N-Load Precision gauges. It serves as a dedicated, chamber-specific platform for accurately measuring cartridge overall length (OAL), a key step in developing safe, accurate handloads.

This 7.62x39mm modified case is manufactured to SAAMI specifications and finished in brass. A special fine thread is cut at the case-head so the case attaches directly to the Lock-N-Load gauge, and the neck is .002" oversized to accept the same bullets used in your reloads, supporting .308-.311 diameter projectiles in this chambering.

Modified cases are the heart of Hornady's OAL gauge system, giving reloaders a quick, repeatable way to establish proper bullet seating depth for a specific rifle chamber. The Lock-N-Load A Series is readily available across the most popular rifle cartridges, making this modified case a go-to bench tool for any 7.62x39mm handloading setup.
