The Hornady Lock-N-Load Overall Cartridge Length Gauge is a must-have tool for any serious handloader. Maintaining consistent overall cartridge length (OAL) is crucial for reliable feeding, consistent accuracy, and preventing damage to your firearm. This gauge simplifies the process, ensuring your ammunition meets the specifications required for your specific firearm. This in-depth review will explore its features, benefits, and how to use it effectively.
Understanding Overall Cartridge Length (OAL)
Before diving into the specifics of the Hornady gauge, let's understand why OAL is so important. Overall cartridge length refers to the total length of a loaded cartridge, measured from the tip of the bullet to the base of the cartridge case. An incorrect OAL can lead to several problems:
- Feeding Issues: Too long, and the cartridge might fail to feed reliably. Too short, and it might not chamber properly.
- Accuracy Problems: Inconsistent OAL leads to inconsistent pressures and inconsistent bullet seating depth, negatively impacting accuracy.
- Damage to Firearm: An excessively long cartridge can damage the firing pin, breech face, or even the barrel of your firearm.
Maintaining a precise OAL is essential for safe and accurate shooting. This is where the Hornady Lock-N-Load Overall Length Gauge comes in.
Hornady Lock-N-Load Overall Length Gauge: Key Features
The Hornady Lock-N-Load Overall Length Gauge is a robust and reliable tool designed for consistent OAL measurement. Key features include:
- Precise Measurement: The gauge provides accurate measurements to ensure your cartridges are within the specified OAL range for your firearm.
- Durable Construction: Made from high-quality materials to withstand repeated use.
- Easy to Use: Its simple design allows for quick and easy cartridge length checks.
- Adjustable Setting: Allows you to set the gauge to your desired OAL.
- Compatibility: Compatible with a wide range of calibers. You'll typically need a specific gauge for each caliber.
- Clear Go/No-Go Indicators: Clearly shows whether your cartridge is within the acceptable OAL range.
How the Gauge Works: A Step-by-Step Guide
- Set the Gauge: Adjust the gauge to the recommended OAL for your specific cartridge and firearm. This information can usually be found in your reloading manual or on the manufacturer's website.
- Insert the Cartridge: Insert the loaded cartridge into the gauge.
- Check the Indicators: Observe the indicators. A “Go” indication means the OAL is within the acceptable range. A “No-Go” indicates the cartridge is either too long or too short.
This simple process provides immediate feedback, allowing you to make adjustments before loading a batch of potentially problematic cartridges.
Benefits of Using the Hornady Lock-N-Load Overall Length Gauge
Using this gauge provides several significant benefits for handloaders:
- Improved Accuracy: Consistent OAL contributes significantly to improved shot grouping and overall accuracy.
- Reliable Feeding: Ensures smooth and consistent feeding of cartridges into the chamber.
- Prevents Damage: Prevents potential damage to your firearm caused by cartridges that are too long.

Choosing the Right Gauge: Caliber Compatibility
It's crucial to select the correct gauge for your specific caliber. Hornady offers gauges for a wide range of calibers, so finding the one you need should be straightforward. Never attempt to use a gauge designed for a different caliber. Doing so could damage the gauge and lead to inaccurate measurements. Always check the manufacturer's specifications for compatibility before purchasing.
