The Hornady Lock-N-Load OAL Gauge is a staple tool for serious reloaders, providing an essential level of precision and consistency in cartridge overall length (OAL) measurement. This comprehensive guide dives deep into its features, benefits, and how to effectively use this critical piece of reloading equipment. Whether you're a seasoned reloader or just starting your journey, understanding the Hornady OAL Gauge is key to producing safe and accurate ammunition.
Understanding Overall Cartridge Length (OAL)
Before we delve into the specifics of the Hornady gauge, let's establish the importance of OAL. Overall length refers to the total length of a loaded cartridge, measured from the tip of the bullet to the base of the cartridge case. Maintaining consistent OAL is paramount for several reasons:
- Reliable Functioning: Inconsistent OAL can lead to feeding and extraction issues in your firearm, potentially causing malfunctions or damage.
- Accuracy: A precise OAL ensures consistent bullet seating depth, which directly impacts accuracy. Slight variations can significantly affect bullet trajectory.
- Safety: Incorrect OAL can lead to dangerously high chamber pressures, potentially causing catastrophic firearm failure.
