Hornady .204 Ruger Lock-N-Load Modified B-Case

The Hornady Lock-N-Load Modified B-Case for .204 Ruger is a precision measurement tool designed to help reloaders determine accurate bullet seating depth relative to the rifling. Built for precision handloading applications, this modified brass case threads directly onto the Hornady Lock-N-Load Overall Length Gauge, allowing chamber-specific measurements during load development and ammunition assembly.

Manufactured from properly headstamped brass, the modified case provides reliable chamber fit while allowing a bullet to be gently advanced toward the rifling using the OAL Gauge system. This process allows reloaders to establish consistent base-to-ogive measurements during the reloading workflow, supporting repeatable seating depth adjustments and consistent ammunition assembly. Accurate seating depth measurement is especially valuable when refining precision rifle loads for high-velocity cartridges such as .204 Ruger used in varmint and long-range shooting applications.
