Lee Double Cavity Mold 457-500-f W/handles Review

Putting the Lee Double Cavity Mold 457-500-f W/handles to Work

For any serious reloader, especially those looking to push the boundaries of precision and economy with their .45-70 Government loads, the Lee Double Cavity Mold 457-500-f W/handles presents itself as a compelling option. My own journey to this particular mold was driven by a desire to increase my casting output without sacrificing the quality of bullets I was producing for my beloved Lever-action rifle. After a few seasons of inconsistent results with a single-cavity mold and struggling to keep up with demand, I knew it was time for an upgrade.

Upon receiving the mold, my first impression was one of utilitarian robustness. It’s cast from what feels like a high-quality aluminum alloy, a material known for its excellent heat transfer and relatively lightweight nature. The inclusion of steel handles was a welcome sight, promising better grip and heat dissipation during extended casting sessions. Compared to the more expensive, multi-cavity molds from other manufacturers, this Lee offering immediately struck me as a practical, no-frills tool designed for efficiency. My initial reaction was a mix of relief and anticipation – relief from the production bottleneck I’d been experiencing, and anticipation for the improved workflow it promised.

Real-World Testing: Putting Lee Double Cavity Mold 457-500-f W/handles to the Test

My testing grounds for this mold were my home casting bench and the shooting range. I set it up on my Lee Production Pot, using a standard alloy of 50/50 lead and wheel weights, with a fluxing agent to ensure clean melts. The initial setup was straightforward; I preheated the mold to the optimal temperature, ensuring a consistent flow of molten lead.

First Use Experience

The first pour was a revelation. The mold heated up quickly and evenly, a testament to its aluminum construction. I experienced a smooth flow of lead into the cavities, and the built-in sprue plate operated with a satisfying click, cleanly separating the excess metal. The machined sprue zerks, a feature often overlooked, truly made for an effortless release, preventing any sticking or tearing of the newly cast bullets.

My only minor surprise was the initial learning curve with the handles. While sturdy, they do require a specific grip to operate the sprue plate efficiently without transferring too much heat to your hands. However, after just a few cycles, this became second nature. This mold performed admirably under repeated use, consistently producing clean, well-formed bullets right out of the gate, even in the dusty environment of my workshop.

Extended Use & Reliability

After several months and hundreds, if not thousands, of casts, the Lee Double Cavity Mold 457-500-f W/handles has proven itself to be a workhorse. It shows no signs of significant wear and tear, the aluminum cavities remain smooth, and the steel handles are still firmly attached. The grain-compressing sprue plate continues to function flawlessly, ensuring each cast is as good as the last.

Maintenance is simple: a quick wipe-down with a soft cloth after each session and a light reapplication of mold release every so often keeps it in peak condition. Compared to some of the more intricate, expensive molds I’ve used in the past, the simplicity of this design translates directly into reliability. There are no complex mechanisms to fail, just solid, well-machined components doing their job consistently. It has certainly outperformed some of the budget, single-cavity molds I started with and holds its own against similarly priced multi-cavity options.

Breaking Down the Features of Lee Double Cavity Mold 457-500-f W/handles

Specifications

The Lee Double Cavity Mold 457-500-f W/handles is designed with the practical reloader in mind. It features a 2-Cavity design, which is the primary reason for its increased production capacity over single-cavity alternatives. The mold is specifically for the .45-70 Government caliber, a testament to its intended use for iconic lever-action rifles and modern renditions of this classic cartridge.

The bullet weight produced is a substantial 500 grain, a perfect weight for heavy-hitting .45-70 loads that excel in both hunting and long-range applications. The bullet type is a Flat Nose (FN), which is crucial for feeding reliability in tubular magazines found in lever-action firearms. The mold itself is constructed from high-tech aluminum, a material known for its excellent heat conductivity, allowing for faster cycle times and more consistent cooling of the cast bullets. This is paired with steel handles, offering superior durability and heat resistance compared to plastic or aluminum handles.

Performance & Functionality

In terms of performance, this mold excels at its core function: producing accurate and consistent 500-grain flat-nose bullets for the .45-70 Government. The tight-curing construction ensures that the cavities maintain their precise dimensions, leading to bullets that drop from the mold with minimal sizing required. The grain-compressing sprue plate is a standout feature, effectively minimizing or eliminating the small “nib” of excess lead that can sometimes form on the base of cast bullets.

The primary strength of this mold is its efficiency. The double-cavity design immediately doubles your output compared to a single-cavity mold. The flat-nose design ensures reliable feeding in lever-action rifles, a critical factor for this caliber. One minor point of consideration is the weight of the bullet itself; while ideal for many applications, it might be too heavy for some specialized low-recoil loads. However, for its intended purpose, it performs exceptionally well.

Design & Ergonomics

The design of the Lee Double Cavity Mold 457-500-f W/handles is focused on functionality and ease of use. The aluminum body is lightweight yet durable, and it heats up quickly for efficient casting. The steel handles are a crucial ergonomic feature; they provide a solid grip and help to dissipate heat, reducing the risk of burns during long casting sessions.

The machined sprue zerks are a thoughtful touch, allowing for easy lubrication of the sprue plate pivot point, ensuring smooth operation and prolonging the life of the mold. The overall feel is one of a tool built for hard work. There’s no unnecessary ornamentation, just well-machined surfaces and robust construction. The flat nose design is clearly indicated, and the overall geometry is optimized for its intended purpose.

Durability & Maintenance

This mold is built to last. The aluminum body, combined with the sturdy steel handles, suggests a high degree of durability for years of consistent use. Under normal casting conditions, there are unlikely to be any significant failure points. The sprue plate and its associated hardware are robust and designed to withstand the rigors of repeated opening and closing.

Maintenance is refreshingly simple. A light cleaning with a soft brush or cloth after each casting session, followed by a gentle application of mold release wax or a light oil, is all that’s needed to keep the cavities clean and the sprue plate operating smoothly. Care should be taken not to overheat the mold, as this can degrade the sprue plate’s integrity over time, but the excellent heat transfer of the aluminum actually helps prevent this by dissipating heat effectively.

Accessories and Customization Options

The Lee Double Cavity Mold 457-500-f W/handles comes ready to cast with its integrated steel handles. While there aren’t extensive customization options for the mold itself, its primary function is to produce a specific bullet profile. However, its compatibility with other casting accessories is a significant advantage.

It works seamlessly with most standard lead pot systems, such as those offered by Lee Precision or other major manufacturers. You can also pair it with various sizing dies and lubing systems from brands like Hornady, RCBS, or Lyman to finish your cast bullets to the precise dimensions required for your firearms. While the mold produces a 500 grain, Flat Nose (FN) bullet, the overall diameter is designed for the .45-70 Government cartridge, fitting within the established reloading dies for this caliber.
