Real-World Testing: Putting Lee Double Cavity Mold .390 Ball W/handles to the Test

First Use Experience

My initial testing of this round ball mold took place in my dedicated casting workshop, a space that’s seen its fair share of lead and flux. The setup was straightforward: a lead pot, a ladle, and the mold itself. I was particularly interested in how the included handles would perform, as flimsy handles can make the entire casting process a precarious affair.

The mold handled molten lead with expected thermal conductivity, heating up efficiently but not excessively. The casting process itself was remarkably smooth; the metal flowed readily into the double-cavity design, filling both perfectly. I experienced no significant issues, with the exception of a slight learning curve in achieving the perfect pour rate to avoid any small imperfections.

What surprised me most was the ease with which the sprue was cut and the cast balls separated. The mold’s alignment was spot-on, and the resulting spheres were remarkably uniform straight out of the gate. There was no need for extensive post-casting work beyond a quick tumble to remove any residual flashing.

Extended Use & Reliability

After several weeks of consistent use, casting batches of .390″ balls for various projects, this Lee mold has held up admirably. I’ve probably cast well over a thousand balls with it, and it shows no significant signs of wear. The aluminum body remains clean with proper care, and the cavities are still as sharp and precise as day one.

Durability has been a strong suit. I’ve accidentally dropped a charged ladle near it once, and while it sustained a minor cosmetic scuff, the mold’s integrity was in no way compromised. There are no cracks, no warping, and the alignment pins remain snug.

Maintenance is refreshingly simple. A quick brush-out after each casting session, along with an occasional wipe-down with a soft cloth and a light application of mold release or an appropriate lubricant, keeps it in pristine condition. Compared to some older, more temperamental molds I’ve used, this double-cavity unit from Lee is a breeze to care for. It consistently delivers clean, well-formed projectiles, far outperforming some of the budget single-cavity molds I started with years ago.

Breaking Down the Features of Lee Double Cavity Mold .390 Ball W/handles

Specifications

This particular Lee Double Cavity Mold .390 Ball W/handles is crafted from durable aluminum, a common and effective material for casting molds due to its excellent heat transfer properties. It features two distinct cavities, each precisely machined to produce round balls with a specified diameter of 0.390 inches. The mold comes equipped with robust, integrated handles that provide a secure and comfortable grip, crucial for safe and efficient casting.

The 0.390″ diameter is a key specification, making it suitable for specific applications where a slightly oversized round ball might be beneficial for barrel engagement or sealing. The stated bullet weight for a projectile cast from this mold is approximately 89.05 grains, offering a consistent mass for reloading. The mold’s cavity depth is listed at 2 inches, which is ample for forming a perfectly spherical ball of this diameter.

These specifications translate directly into performance. The double-cavity design effectively doubles your output compared to a single-cavity mold, significantly speeding up larger casting projects. The 0.390″ diameter is ideal for certain muzzleloading applications or for experimenting with oversized projectiles in smoothbore firearms. The aluminum construction ensures rapid heating and cooling cycles, leading to faster casting times and reduced lead waste from cooling too quickly.

Performance & Functionality

The primary job of the Lee Double Cavity Mold .390 Ball W/handles is to cast precise, spherical lead balls, and in this regard, it excels. Each cast consistently produces round balls that are virtually identical, with minimal to no visible imperfections. The 0.390″ diameter is accurately maintained, which is critical for ensuring proper fit and predictable performance in firearms.

Its main strength lies in its remarkable consistency. Once the mold reaches optimal temperature, every ball cast emerges perfectly round and uniform, minimizing the need for sorting or further processing. The included handles are a significant functional advantage; they stay relatively cool and provide excellent leverage, making it easier to manage the mold during pouring and shaking.

The only area that might be considered a slight weakness, though inherent to casting itself, is the slight oversizing for some applications. While 0.390″ is specified, it might be a touch large for some .380 or .38 Special firearms that typically use smaller diameter balls. However, this is a design choice for specific purposes and not a flaw in the mold’s execution.

Design & Ergonomics

The design of this Lee mold is classic and functional. The aluminum body is smooth and free of sharp edges, apart from the precise parting line of the cavities. The double-cavity layout is efficiently spaced, allowing for easy pouring without interference between cavities.

The integrated handles are a standout ergonomic feature. They are shaped to fit comfortably in the hand, with a textured surface that enhances grip even with slightly greasy hands. Their robust construction means they don’t flex or twist under pressure, providing confidence when handling hot lead.

The sprue plate mechanism, common to Lee molds, is simple and effective, allowing for a clean break of the excess lead. Overall, the mold feels well-balanced and intuitive to use, even for someone new to casting. There’s no complex assembly or finicky adjustments required, making it ready to cast right out of the box.

Durability & Maintenance

From my experience, Lee molds, especially those made from aluminum like this one, are built for longevity. This double-cavity unit is no exception. Under normal casting conditions, with proper care, this mold is likely to last for many years, perhaps even decades, of regular use.

Maintenance is straightforward. After each casting session, I let the mold cool slightly, then brush out any lead residue or flux. A light application of mold release agent before the next casting session ensures that the lead flows smoothly and prevents sticking. I have not encountered any issues with the mold sticking or requiring excessive force to open.

Potential failure points are minimal. Extreme overheating could theoretically warp the aluminum, but this requires sustained abuse far beyond typical casting practices. The pivot points for the handles and sprue plate are simple and robust, showing no signs of wear.

Accessories and Customization Options

The Lee Double Cavity Mold .390 Ball W/handles typically comes as a complete unit with the mold block and attached handles. While there aren’t extensive included accessories, the design itself is part of a larger ecosystem. Lee offers a variety of other mold sizes and types, often sharing similar handle designs, which can sometimes be interchanged.

Beyond the mold itself, successful casting relies on essential auxiliary equipment. This includes a lead melting pot, a casting ladle, heat-resistant gloves, eye protection, and a source for lead alloy. For this specific mold, a standard sprue cutter is essential for trimming the excess lead.

The primary “customization” comes from the lead alloy you choose and the pouring temperature. Experimenting with different alloys (e.g., pure lead vs. alloys with tin and antimony) can subtly affect the finished ball’s hardness and castability. This mold is designed for standard lead alloys commonly used in casting.
