Hornady OAL Gauge curved gauge #C1550 for semi-automatics & pump-action

Precise, curved OAL gauge for specific feeding types and process reliability Compatible, reproducible, and tested The Hornady OAL Gauge curved gauge #C1550 was specially developed for semi-automatics, lever-action rifles, and pump-action firearms, offering a practical solution for the exact determination of overall length (OAL). The curved design ensures correct guidance in systems with angled cartridge feeding, reduces measurement errors caused by skewed feeding, and enables reliable, reproducible measurement results in serial production or workshop operation. Manufacturing and material selection are designed for industrial continuous use; the gauge is produced with tight tolerances and undergoes Hornady’s documented quality controls, so users receive reliable reference values and can detect measurement deviations early. In practice, the gauge ensures faster setup times, standardized calibration processes, and a significant reduction in rejects because seating depths and transition lengths are reproducibly determined. Handling is user-friendly: insert, place, read — the gauge can be intuitively integrated into existing OAL workflows and is compatible with common modified cases and measuring devices. For long-range applications and match setups, the precise determination of the contact length to the start of the rifling provides decisive advantages in ballistics optimization and shot group stability. Hornady provides technical specifications, care instructions, and testing notes to ensure measurement precision over the lifecycle and facilitate integration into quality assurance processes. Choose the Hornady OAL Gauge curved gauge #C1550 if you need process stability, documented measurability, and reproducible OAL values for semi-automatic and pump-action platforms. The Ogive comparison gauge Hornady B-234 is recommended for performing comparative measurements on the ogive.
