Hornady LNL OAL Gauge modified case for OAL gauge "A" .308 WIN

Precision case for reliable length measurement and calibration Compatible, process-stable, and tested for reloading quality The Hornady OAL Gauge modified cartridge case #A308 is a precision-crafted measuring tool designed for reproducible overall length measurements (OAL) and as a reference case together with the base unit Hornady OAL Gauge straight gauge for bolt-action/single-shot rifles #C1000 or the variant Hornady OAL Gauge curved gauge for semi-automatic, lever-action, pump-action rifles #C1550 in the quality control of reloading processes. Developed for workshop and laboratory conditions, the case offers an exact internal and external contour that ensures distortion-free guidance in OAL gauges; the result is consistent measurement values, reduced measurement scatter, and faster testing cycles. The choice of material and heat treatment meet industrial manufacturing standards, Hornady documents tolerances and batch tests; users thus receive traceable quality parameters for integration into test protocols. In practice, the modified case increases efficiency when calibrating seating depths, comparing different bullet profiles, and setting up reloading presses, as it acts as a stable reference and makes deviations visible early. Compatibility tests with common OAL gauges have been conducted; the case fits standard measuring devices and avoids necessary adjustments to the measuring instrument. For operators, this means reduced setup times, lower reject rates, and better process capability (Cpk). Hornady provides technical specifications, handling instructions, as well as care and storage recommendations to maintain measurement precision throughout the entire lifecycle. The case is aimed at professional reloaders, laboratory operations, and service workshops that demand process reliability, traceability, and documented measurement results.
