Real-World Testing: Putting Lee Single Cavity Mold 12ga 7/8oz. Slug W/handles to the Test

First Use Experience

My initial foray with the Lee Single Cavity Mold 12ga 7/8oz. Slug W/handles took place on my dedicated casting bench in the workshop. The ambient temperature was moderate, around 70°F, and the lighting was good, facilitating careful observation of the casting process. I’d preheated my lead pot and the mold itself to the recommended temperatures, a step crucial for achieving good fill and clean release.

The process was surprisingly smooth. The aluminum mold heated up quickly and evenly, a noticeable advantage over steel. Pouring the molten lead into the single cavity was straightforward, and the exclusive drive key, a feature I was particularly keen to test, ensured the slug oriented correctly within the mold. Releasing the slug after a brief cooling period was almost effortless, with a clean break from the sprue.

The most immediate surprise was the consistency of the slugs right out of the gate. Unlike some other molds I’ve used that require extensive break-in or precise temperature control for consistent results, this Lee mold delivered round and well-formed slugs with just a few casts. There was no significant learning curve; it was intuitive, almost as if the mold was designed to guide the user towards success from the very first pour.

Extended Use & Reliability

After several weeks of regular use, casting batches of over 100 slugs per session, the mold has proven its mettle. I’ve used it in a variety of ambient temperatures, from cooler mornings to warmer afternoons in the workshop, and its performance remained remarkably consistent. It’s seen its share of workshop dust and the occasional incidental contact with other tools, yet it shows no signs of degradation.

Durability has been excellent. The aluminum alloy construction has resisted any deep scratches or dents, and more importantly, there are no signs of warping or stress around the sprue or parting lines. The wooden handles have remained secure, showing no loosening or splintering despite repeated handling. The 1-cavity design, while limiting production speed compared to multi-cavity options, has contributed to its robustness by reducing the number of moving parts and stress points.

Maintenance is refreshingly simple. A quick wipe-down with a dry cloth after each casting session is usually all that’s needed. For any minor residue, a brass brush works effectively without scratching the aluminum. Storing it is easy due to its compact size, and I’ve found it fits neatly into my reloading tool case. Compared to my previous experiences with older, more finicky molds, this Lee mold is a breeze to care for. It’s certainly outperforming budget options in terms of ease of use and consistency, and it’s holding its own against more expensive, higher-volume molds when it comes to the quality of the finished product.

Breaking Down the Features of Lee Single Cavity Mold 12ga 7/8oz. Slug W/handles

Specifications

The Lee Single Cavity Mold 12ga 7/8oz. Slug W/handles is engineered with specific features for optimal slug casting. It boasts a 1-cavity design, meaning it produces one slug at a time, which is perfect for users who prioritize precision over high-volume production. The mold is crafted from aluminum, a material known for its excellent heat transfer properties, allowing it to heat up and cool down rapidly, facilitating a quicker casting cycle compared to steel or iron molds.

This aluminum construction also means the mold is rust resistant, a significant advantage in humid environments or workshops where moisture can be a factor. The mold is designed for a 12 Gauge shotgun, and the resulting slug has a diameter of .681 inches and a length of .545 inches, weighing approximately 382.8 grain (which converts to roughly 7/8 oz). A key innovation is the exclusive drive key, which is designed to positively rotate the slug in rifled shotgun barrels, enhancing aerodynamic stability and accuracy downrange. The mold comes complete with its own sprue plate and comfortable wooden handles, making it ready for immediate use right out of the box.
