Hornady Lock-N-Load 7mm WSM Modified Case

The Hornady Lock-N-Load Modified Case is a precision reloading accessory chambered in 7mm WSM, designed to work with Hornady's Lock-N-Load Precision gauges for measuring and tuning bullet seating depth and overall cartridge length.

Each modified case is manufactured to SAAMI specifications and features a special fine thread machined into the case-head, allowing it to thread directly onto the Lock-N-Load Precision gauge. This threaded attachment holds the case perfectly square during measurement, eliminating alignment error and giving handloaders a reliable, repeatable reference point for dialing in their bullet seating depth.

The neck is precisely formed .002" oversized so it accepts the same projectiles the reloader intends to load, allowing realistic bullet jump, run-out, and seating depth checks rather than dummy-round approximations. Brass construction matches the fired case material you will be loading for consistent feel and fit during setup.

Sold as a single modified case (part number B7WS), this piece is an essential shop tool for any 7mm WSM handloader running the Hornady Lock-N-Load gauge system to optimize their reloads.
