Lee Precision is a well-known name in the reloading world, and their 20-gauge slug mold is a popular choice for those who want to cast their own slugs. This comprehensive guide will delve into the details of the Lee 20 Gauge Slug Mold, exploring its features, benefits, use, and considerations. We'll cover everything from setup and operation to troubleshooting and maintenance, ensuring you get the most out of your slug casting experience.
Understanding the Lee 20 Gauge Slug Mold
The Lee 20 Gauge Slug Mold is a two-cavity mold, meaning it casts two slugs simultaneously. This significantly increases efficiency compared to single-cavity molds. It's designed for use with lead alloy, providing a cost-effective way to produce ammunition for shotguns. The mold's design prioritizes ease of use, making it suitable for both beginners and experienced reloaders. The simplicity, coupled with its effectiveness, contributes to its popularity. We'll examine its specific features in more detail below.
Key Features and Benefits of the Lee 20 Gauge Slug Mold
-
Two-Cavity Design: This doubles your output per pour, saving you valuable time and effort during your reloading sessions. This efficiency is particularly beneficial when casting large quantities of slugs.
-
Simple Operation: The mold's straightforward design minimizes complexity. Even those new to slug casting can quickly learn to operate it effectively. The instructions provided are usually clear and concise.
-
Cost-Effective: Casting your own slugs with lead alloy is significantly cheaper than purchasing commercially produced slugs. This makes it an attractive option for those who frequently shoot slugs. The initial investment in the mold is quickly recouped through savings.
-
Consistent Slug Quality: With proper technique and alloy preparation, the Lee 20 Gauge Slug Mold produces slugs of consistent weight and dimensions. This consistency contributes to accuracy and reliability on the range.
-
Durable Construction: Lee Precision molds are generally known for their robust construction, able to withstand the rigors of repeated use. This durability ensures a long lifespan for your investment.
Setting Up and Using the Lee 20 Gauge Slug Mold
Before you begin, you'll need the following:
- Lee 20 Gauge Slug Mold: The primary component of the operation.
- Lead Alloy: Obtain a suitable lead alloy specifically designed for slug casting. Experimentation may be required to find the ideal alloy for your needs.
- Melting Pot: A suitable melting pot for safely melting your lead alloy. Consider safety precautions when working with molten lead.
- Ladle: To transfer molten lead to the mold.
- Safety Gear: Eye protection, gloves, and a well-ventilated area are crucial for safe operation.
Step-by-Step Guide:
-
Prepare the Mold: Ensure the mold is clean and free of debris. A light coating of mold release agent might be beneficial.
-
Melt the Lead: Carefully melt your lead alloy in your melting pot. Maintain a consistent temperature.
-
Pour the Lead: Using the ladle, carefully pour the molten lead into the cavities of the mold. Avoid splashing.
-
Cool and Remove: Allow the slugs to cool completely before removing them from the mold.
-
Clean and Repeat: Clean the mold after each use to maintain its integrity and ensure consistent slug quality.
Troubleshooting Common Issues
-
Slugs Sticking: This is often caused by insufficient mold release agent or impurities in the lead alloy. Try using a mold release agent and ensuring the lead is clean.
-
Inconsistent Slug Weight: This might indicate inconsistencies in the pouring process or problems with the lead alloy. Ensure consistent pouring and check your alloy composition.
-
Damaged Slugs: This could be due to improper mold maintenance or using a lead alloy that's too cold. Ensure proper mold cleaning and a suitable pouring temperature.
Case Study: Improving Accuracy with Alloy Composition
One reloader found that switching from a standard wheel weight alloy to a harder alloy with the addition of tin significantly improved the accuracy of their cast slugs. The harder alloy resulted in better slug integrity and less deformation during firing. This underscores the importance of experimenting with different alloy compositions to optimize performance.
Conclusion: The Lee 20 Gauge Slug Mold – A Valuable Tool for Reloaders
The Lee 20 Gauge Slug Mold offers a cost-effective and efficient way to produce your own 20-gauge slugs. While some experimentation may be required to achieve optimal results, its simplicity and robust construction make it a valuable tool for both beginners and experienced reloaders. Remember to always prioritize safety and follow proper procedures when working with molten lead. The savings and satisfaction of casting your own ammunition far outweigh the minor learning curve.
