Lee Large Hardness Test Kit
Determine exact Brinell hardness of lead alloys in six simple steps. Includes pocket microscope and conversion chart for maximum operating pressure. Cast and load with confidence.
Lee Large Hardness Test Kit
Knowing the hardness of your cast lead alloys is fundamental to safe and efficient reloading. This comprehensive kit allows you to determine the exact Brinell hardness number of any alloy through a straightforward six-step process.
What's Included
- Hardness testing apparatus
- Lee Pocket Microscope for precise measurement
- Conversion chart correlating hardness to maximum operating pressure
Why Hardness Matters
Cast lead bullets that are too soft will deform under pressure, leading to leading in your barrel and inconsistent velocities. Alloys that are too hard may not obturate properly, causing accuracy issues and potential pressure spikes. This kit eliminates the guesswork.
How It Works
The simple six-step testing process requires no special equipment or expertise. Once you've determined your alloy's Brinell number, the included conversion chart immediately tells you the maximum safe operating pressure for that specific hardness.
The Result
Cast and reload with confidence, knowing your alloys are properly suited to your loads. No more wasted components from shooting lead that's either too soft or too hard. This kit has earned its place as a featured resource in Modern Reloading, the definitive guide to the craft.
