The Hornady Lock-N-Load Overall Length Gauge is an indispensable tool for serious reloaders. Maintaining consistent cartridge overall length (OAL) is crucial for reliable feeding, consistent chamber pressure, and optimal accuracy. This gauge provides a simple yet effective way to ensure every round meets your desired specifications. This detailed review will explore its features, benefits, and how to use it effectively.
Understanding Cartridge Overall Length (OAL)
Before diving into the specifics of the Hornady gauge, let's clarify why OAL is so important. OAL refers to the total length of a loaded cartridge, measured from the tip of the bullet to the base of the cartridge case. Inconsistent OAL can lead to several problems:
- Feeding Issues: Cartridges that are too long may fail to feed reliably into the chamber, causing jams or malfunctions. Cartridges that are too short can also create feeding problems, especially in semi-automatic firearms.
- Pressure Variations: Significant variations in OAL can result in inconsistent chamber pressure, potentially leading to dangerous over-pressure situations or underperforming rounds.
- Accuracy Degradation: Inconsistent OAL directly impacts bullet seating depth, which in turn affects accuracy. Slight variations can lead to noticeable differences in point of impact.
Hornady Lock-N-Load Overall Length Gauge: Key Features & Benefits
The Hornady Lock-N-Load Overall Length Gauge stands out for its simplicity, precision, and ease of use. Key features include:
- Adjustable Go/No-Go Settings: The gauge allows you to quickly and precisely set the desired OAL. The "Go" setting indicates the cartridge is within the acceptable length range, while the "No-Go" setting signals it’s outside the acceptable parameters. This dual-functionality is essential for precise quality control.
- Durable Construction: Built from high-quality materials, the gauge is designed to withstand the rigors of repeated use in a reloading bench environment. It's built to last.
- Clear Markings: The gauge features clear and easy-to-read markings for setting and checking OAL. This makes it simple even for beginner reloaders.
- Caliber Specific: Hornady offers the gauge for a wide variety of calibers, ensuring a precise fit for your specific ammunition. This eliminates any guesswork or potential inaccuracies.
- Efficient Workflow: The simple design ensures a smooth and efficient workflow within your reloading process. Checking OAL becomes a quick and routine part of your reloading procedure.
How to Use the Hornady Lock-N-Load Overall Length Gauge
Using the gauge is straightforward:
- Set the Desired OAL: Consult your reloading manual or published data for the recommended OAL for your specific cartridge. Use the adjustment mechanism on the gauge to set both the "Go" and "No-Go" limits.
- Insert the Cartridge: Carefully insert the loaded cartridge into the gauge.
- Check the Result: Note whether the cartridge falls within the "Go" or "No-Go" range. If it falls within the "Go" range, the OAL is acceptable. If it falls within the "No-Go" range, the cartridge requires adjustment before being considered suitable for use.
Beyond the Basics: Tips for Optimal Use
- Consistent Measurement: For optimal accuracy, always use the same gauge for all your cartridges of a given caliber.
- Regular Calibration: While the Hornady gauge is robust, it's advisable to occasionally check its calibration against a known reliable measurement tool.
- Cleanliness: Keep your gauge clean and free of debris to ensure accurate measurements.
Conclusion: A Valuable Investment for Serious Reloaders
The Hornady Lock-N-Load Overall Length Gauge represents a worthwhile investment for any serious reloader. Its precision, ease of use, and durability make it an invaluable tool for ensuring consistent and safe ammunition. By maintaining accurate OAL, you ensure your ammunition performs reliably, providing better feeding, consistent pressure, and enhanced accuracy. Investing in this tool is a key step towards optimizing your reloading process and producing high-quality ammunition.
