The Hornady Lock-N-Load O.A.L. Gauge Curved Model (C1550) is a red, multi caliber overall length gauge designed to work with Hornady modified cases so you can measure bullet seating depth and cartridge overall length through the ejection port of repeaters. This curved OAL gauge is built for autoloaders, lever actions, and pump rifles where you cannot access the chamber straight from the rear, and it also fits bolt action and single shot rifles.

Special Features
- Curved body design routes the gauge through the ejection port, making it workable on rifles where straight line chamber access is blocked by the action.
- Internal push rod allows you to seat an actual bullet into the rifling using your chosen projectile, instead of a generic dummy.
- Thumb screw locks the rod in place after the bullet contacts the lands so you can remove the gauge and transfer the measurement to calipers without losing position.
- Works as part of the Hornady Lock-N-Load measurement system with modified cases, headspace tools, and bullet comparators to standardize seating depth setup.
Practical Benefits
- With the Hornady Lock-N-Load O.A.L. Gauge Curved Model (C1550), you can determine true cartridge overall length to the lands in rifles that do not allow rear straight line access, such as many autoloaders and lever guns.
- Using this gauge with modified cases helps you keep bullet jump consistent across different bullets and load batches, which supports better accuracy and reliability in field and range use.
- If you run semi automatic, lever, or pump rifles and want the same level of seating depth control you expect from bolt guns, the Hornady C1550 curved OAL gauge is a dependable option that extends precise OAL measurement across your whole rifle lineup.
