Hornady Lock-N-Load O.A.L. Gauge, Curved, Multi Caliber

The Hornady Lock-N-Load O.A.L. Gauge, curved version (brand part no. C1550), is a precision tool for measuring seating depth and the resulting bullet jump to the rifling in your specific rifle. Hornady built the curved gauge to work across autoloader, lever, and pump-action rifles as well as bolt-action and single-shot firearms, giving handloaders one tool that covers most rifle actions. It is not compatible with the Adapter D attachment or short-bodied cases, and using it requires a modified case fitted to your specific chamber, which is not included with the gauge. It measures roughly 15.65 inches overall.
