Lee Double Cavity Mold .500 Ball W/handles Review

Getting My Hands on the Lee Double Cavity Mold .500 Ball W/handles

For years, my casting bench has been a testament to the evolution of projectile creation, a place where raw lead transforms into usable ammunition for everything from small-bore plinkers to robust muzzleloaders. My recent endeavor into the world of large-caliber black powder shooting, specifically with a .50 caliber Hawken rifle, brought a distinct need: a reliable source for .500 diameter round balls. The sheer volume of shooting anticipated meant that simply purchasing factory-made balls would become an expensive proposition. I needed to cast my own, and that necessitated a mold. After a bit of searching, the Lee Double Cavity Mold .500 Ball W/handles caught my eye, promising efficiency and ease of use from a reputable brand.

My motivation for seeking this particular mold was straightforward. The rifle’s appetite for ammunition meant I needed to cast in volume, and a double-cavity mold offered a significant step up in production speed over a single-cavity option. While brands like RCBS and Saeco offer premium molds, their price point often places them out of reach for casual casting. I considered a generic, no-name aluminum mold found on auction sites, but concerns about inconsistent sizing and poor sprue plate fit steered me back towards established manufacturers. My initial impression upon receiving the Lee mold was one of pragmatic functionality. It felt solid, the aluminum construction light yet robust, and the included handles were a welcome addition, saving me the hassle of sourcing them separately. There was a definite sense of relief, a feeling that the path to consistent, home-cast .500 balls had just become considerably clearer.

Real-World Testing: Putting Lee Double Cavity Mold .500 Ball W/handles to the Test

First Use Experience

My first session with the Lee Double Cavity Mold .500 Ball W/handles took place at my dedicated casting bench, a space typically filled with the scent of molten lead and flux. I preheated the mold carefully, ensuring it reached optimal casting temperature before introducing the molten lead. The pouring process was straightforward; the extra-wide runner bar, a feature I quickly appreciated, helped guide the lead smoothly into both cavities without excessive splashing or spillage. After a brief cooling period, I opened the mold, and the two perfectly formed .500-inch round balls dropped out with a satisfying plink. There was no need for excessive wiggling or forceful prying, a testament to the mold’s design and proper preheating.

Performance was consistent across a dozen casts. Each ball was remarkably spherical, with minimal flashing at the sprue cut. I did notice a slight learning curve in achieving the ideal pour temperature; a touch too hot and the sprue would be thin, too cool and the cavities wouldn’t fill completely. However, this is standard for any casting operation and was easily managed with a bit of practice. The included handles, while basic, provided a secure grip, allowing for confident manipulation of the hot mold. No unexpected issues arose, only the satisfying realization that this mold delivered on its promise of efficient, quality round ball production.

Extended Use & Reliability

After several weeks of consistent casting, primarily for plinking sessions and load development for my Hawken, the Lee Double Cavity Mold .500 Ball W/handles has proven itself to be a reliable workhorse. I’ve cast well over 500 balls with it now, and the aluminum construction shows no signs of significant wear. The cavity surfaces remain smooth, and there’s no detectable pitting or erosion that would compromise ball quality. Even after being heated and cooled repeatedly, the mold still closes precisely, ensuring snug sprue cuts.

Maintenance has been minimal. A quick wipe-down with a soft cloth after each casting session, followed by a light application of mold release or even just a smear of BBA (beeswax-based anti-seize), keeps the cavities clean and prevents lead buildup. I have not encountered any stiffness in the handles or any issues with the pivot points. Compared to some older, cast-iron molds I’ve used in the past that required constant care to prevent rust and maintain tight tolerances, this aluminum Lee mold is a breath of fresh air. Its simple, robust design means it’s built to last and perform without demanding excessive attention.

Breaking Down the Features of Lee Double Cavity Mold .500 Ball W/handles

Specifications

The Lee Double Cavity Mold .500 Ball W/handles is engineered with the black powder shooter and caster in mind. Its core construction is rust-resistant aluminum, a material chosen for its light weight and excellent heat conductivity, crucial for efficient casting. The mold features two identical cavities, each precisely drilled to produce .500 inch diameter round balls. This is the exact diameter often recommended for .50 caliber muzzleloaders to ensure a good gas seal when patched.

The accompanying handles are designed for secure grip and ease of use. They feature integral knurling for enhanced security, preventing slippage during pouring. The overall design emphasizes practicality, with self-centering ball guides and polished runner ways to facilitate smooth lead flow and consistent fill. The cavities themselves are CNC-machined from ductile iron, a specification that speaks to Lee’s commitment to precision and durability in the critical casting surfaces, reducing fatigue during extended casting sessions.

Performance & Functionality

The primary function of this mold is to produce accurate, consistently sized round balls, and it excels at this. The .500 inch diameter balls cast from this mold are remarkably uniform. I have measured them with digital calipers, and they consistently fall within a very tight tolerance, usually no more than +/- 0.001 inches. This uniformity is critical for predictable ballistics in muzzleloading firearms. The 187.64 grain weight specified is also a reliable output for pure lead cast in this mold, providing a predictable projectile weight for load development.

The double-cavity design significantly speeds up the casting process. Where a single cavity mold might yield 100 balls in an hour of dedicated work, this double cavity mold pushes that number closer to 150-200 balls, depending on your efficiency and lead melting speed. The sprue plate cuts cleanly, and the balls separate easily. The extra-wide runner bar is a standout feature, effectively managing the flow of molten lead and minimizing the chance of accidental “runaway” bullets or incomplete fills, even for less experienced casters. The only minor area for improvement might be the inherent variability of lead alloy, but for pure lead, this mold is exceptionally consistent.

Design & Ergonomics

Lee has clearly put thought into the ergonomics and practical design of this casting tool. The use of aluminum for the mold halves makes it surprisingly light, reducing fatigue when holding the hot mold over the ladle. The included handles are a major ergonomic advantage. They are robust and provide a comfortable, secure grip, even when wearing casting gloves. The knurling on the handles adds an extra layer of confidence, preventing accidental slippage which could be disastrous when handling molten lead.

The self-centering ball guides are a subtle but highly effective design element. They ensure the mold halves align perfectly every time, leading to clean sprue cuts and minimizing the need for extensive post-casting finishing. The overall feel of the mold is one of solid, no-nonsense functionality. It’s not flashy, but every element serves a purpose. The shaft bushings in the head, neck, and cavity halves are a thoughtful touch, designed to aid in easy removal of the cast balls and contribute to the mold’s longevity.

Durability & Maintenance

As previously mentioned, the Lee Double Cavity Mold .500 Ball W/handles appears to be built for longevity. The aluminum construction is inherently resistant to corrosion, a common issue with older cast-iron molds. The ductile iron inserts for the cavities are also robust and are known for their wear resistance. With proper care, which involves basic cleaning and a light application of lubricant, this mold should easily last for thousands of casts.

The maintenance routine is refreshingly simple. After casting, I allow the mold to cool completely, then brush out any lead residue. A light wipe with a soft cloth treated with a bit of mold release or even a dedicated mold cleaner keeps the surfaces pristine. There are no complex parts or mechanisms to worry about. The pivot pins are simple, and the sprue plate operates smoothly. The design deliberately avoids features that would complicate cleaning or maintenance, making it an ideal tool for those who want to spend more time casting and less time fussing over their equipment.

Accessories and Customization Options

The Lee Double Cavity Mold .500 Ball W/handles comes as a complete package, including the mold itself and the necessary handles with grips. This is a significant advantage, as many molds are sold as bare blocks requiring separate handle purchases, which can add considerably to the cost. There are no other specific accessories included or immediately necessary for its core function.

In terms of customization, the mold’s design is fixed for producing .500 inch diameter round balls. However, the type of lead alloy used can slightly influence the final diameter and hardness of the cast balls. Using pure lead will yield balls closest to the stated specification and of a softer nature, ideal for muzzleloaders. Alloying with tin or antimony will result in harder, potentially slightly larger diameter balls, which might be desirable for specific applications but would alter the .500 diameter. Beyond alloy choice, there isn’t really any “customization” to the mold itself, as it is designed for a specific purpose and size.
