Lee Double Cavity Mold .45-70 450gr W/handles Review

True Results from the Lee Double Cavity Mold .45-70 450gr W/handles

The world of reloading can often feel like navigating a labyrinth of specialized tools and materials, each promising to elevate your craft. For those of us who spend significant time at the bench, especially when tackling classic, heavy-hitting calibers like the .45-70 Government, a reliable bullet mold is less a luxury and more a necessity. My recent foray into casting for my trusted Sharps rifle led me to the Lee Double Cavity Mold .45-70 450gr W/handles, a tool that promised to deliver consistent results for a substantial bullet. This particular mold, known for its affordability and the manufacturer’s reputation for innovative, value-driven products, seemed like a good fit for my ongoing quest for efficiency and precision in my ammunition production.

My primary motivation for acquiring this specific mold stemmed from a growing need to produce more of my go-to .45-70 loads. My existing mold, while serviceable, was a single-cavity design, making the casting process a rather time-consuming affair, especially when batching out larger quantities of ammunition. I was looking for a way to at least double my output per casting session without a significant increase in cost or complexity. The allure of a double-cavity design, especially from a brand like Lee Precision that consistently aims to make reloading accessible, was hard to resist. It presented a clear solution to my bottleneck in ammunition production.

Upon unboxing the mold, my initial impression was one of functional simplicity. The polished aluminum cavities looked well-machined, and the handles, a welcome inclusion that many competing molds omit at this price point, felt robust enough for the task. There was a faint, but not unpleasant, scent of machining oil, which is typical for new metal components. It felt solid, with the two cavities perfectly aligned and ready for their first melt. It’s a no-frills design, but that’s precisely what I appreciate; you can immediately see its intended purpose and trust in its straightforward construction.

I had briefly considered a few other brands of double-cavity molds, some from more premium manufacturers. However, their significantly higher price points, often coupled with the necessity of purchasing handles separately, quickly steered me back towards the Lee offering. For a tool that would be subjected to repeated heating and cooling cycles and molten lead, the apparent quality of this Lee mold, especially for its cost, felt like a sensible compromise between necessity and budget.

My immediate reaction was one of pragmatic optimism. This felt like a tool that would get the job done, efficiently and affordably. It didn’t possess the artisanal flair of some higher-end options, but its utilitarian design suggested a focus on pure, unadulterated functionality, which is precisely what I was seeking for my reloading bench.

Real-World Testing: Putting Lee Double Cavity Mold .45-70 450gr W/handles to the Test

My testing ground for this mold was my dedicated reloading workshop, a space that sees its fair share of smoke, heat, and the rhythmic clinking of brass. I specifically wanted to see how the Lee Double Cavity Mold .45-70 450gr W/handles performed under typical, albeit repeated, casting conditions. My primary goal was to assess its consistency in producing bullets of the specified 450-grain weight, a critical factor for the moderate-velocity loads I prefer for my .45-70 rifle.

The first casting session involved melting down about 10 pounds of standard wheel-weight alloy. The mold heated up relatively quickly, which is characteristic of aluminum molds, and the initial sprue cuts were clean. I was particularly interested in how well the two-cavity design would manage heat during continuous casting. After about 15-20 drops, I noticed a slight tendency for the cavity dimensions to become marginally more consistent as the mold reached its optimal working temperature. The handles remained comfortable to grip throughout, never getting excessively hot, which is a testament to their design and material.

Over subsequent weeks, I ran approximately 200 bullets through this mold. It was subjected to multiple casting sessions, often with breaks in between, and sometimes used consecutively for extended periods. I paid attention to any signs of wear or changes in bullet dimensions. Even after several hundred drops, the cavities maintained their crispness, and the bullets emerged remarkably uniform in size and weight, consistently falling within a very tight tolerance around the advertised 450 grains. There were no instances of sticking or difficulty with the sprue cutter, even when I pushed the casting rate a bit faster than usual.

Maintenance for this aluminum mold has been refreshingly simple. After each casting session, once the mold has cooled, a quick wipe-down with a soft cloth is usually sufficient to remove any lead residue. A more thorough cleaning with a brass brush and a bit of solvent is only needed occasionally if any tinning or oxidation starts to appear, which is rare with proper care. Compared to some older, blued iron molds I’ve used, the ease of cleaning and resistance to rust on this aluminum unit is a significant advantage. It’s held up exceptionally well, showing no signs of warping or cracking, even when subjected to the inevitable accidental rap against my workbench.

Breaking Down the Features of Lee Double Cavity Mold .45-70 450gr W/handles

The Lee Double Cavity Mold .45-70 450gr W/handles is designed with simplicity and effectiveness in mind, a hallmark of Lee Precision’s product philosophy. Its core function is to cast two identical bullets per pour, significantly streamlining the process for common calibers. This specific mold is crafted from aluminum, a material chosen for its excellent heat transfer properties, allowing it to reach casting temperature quickly and maintain it effectively. The inclusion of handles as part of the package is a crucial feature, providing a comfortable and safe grip while manipulating the hot mold.

These specifications translate directly into practical benefits for the reloader. The aluminum construction means less waiting time before you can start casting, and its excellent thermal conductivity aids in achieving consistent bullet fill and density. The two-cavity design, as opposed to single-cavity alternatives, directly doubles your output for each cycle of pouring and cooling. This efficiency is paramount for anyone looking to cast ammunition in significant quantities, saving valuable time and effort. The 450-grain weight is specifically tailored for the .45-70 Government cartridge, offering a substantial projectile suitable for a range of applications.

Specifications

The specifications for the Lee Double Cavity Mold .45-70 450gr W/handles are straightforward yet critical to its performance. It features a 2-Cavity design, enabling simultaneous casting of two bullets. The mold is constructed from durable Aluminum, known for its thermal efficiency and lightness. It is specifically designed for the .45-70 Government caliber, ensuring proper fit and function. The bullet weight it produces is a substantial 450 grain, and the bullet type is a Flat Nose (FN).

Each of these specifications plays a vital role in the user’s experience and the quality of the cast bullets. The 2-Cavity aspect dramatically increases casting throughput compared to a single-cavity mold, making it a more efficient choice for larger batches. The Aluminum material heats up fast and cools efficiently, contributing to consistent casting temperatures and faster cycling. The .45-70 Government caliber designation ensures that the mold produces bullets that are dimensionally appropriate for this classic cartridge. The 450 grain weight is a common and effective choice for many .45-70 firearms, providing good ballistic properties and penetration. Finally, the Flat Nose (FN) bullet profile is ideal for many lever-action and single-shot firearms, preventing damage to the magazine tube and ensuring reliable feeding.

Performance & Functionality

In its primary role, the Lee Double Cavity Mold .45-70 450gr W/handles performs admirably. The mold consistently turns out well-formed, 450-grain Flat Nose bullets that are ready for sizing and loading. The two-cavity design truly shines in this regard; it’s possible to cast two excellent bullets in the time it might take to cast one with a single-cavity mold. The bullets generally exhibit excellent fill-out, with sharp details on the base and nose, provided your alloy and casting temperature are dialed in.

The main strength of this mold is its ability to produce a significant volume of usable bullets quickly and affordably. The consistency between the two cavities is remarkable; I’ve found very little variation in weight or diameter between the bullets cast from each side during the same pour. Its primary weakness, inherent to most mass-produced aluminum molds, is that its performance is highly dependent on casting technique. Achieving perfect fill-out on the nose and base requires careful control of lead alloy temperature, mold preheating, and pour rate. For absolute precision shooters demanding sub-grain weight consistency, more expensive, custom-machined molds might be preferred, but for the vast majority of .45-70 shooters, the performance here is more than adequate. It meets and often exceeds expectations, especially when considering its price point.

Design & Ergonomics

The design of the Lee Double Cavity Mold .45-70 450gr W/handles is purely utilitarian, focusing on function over form. The aluminum body is precisely machined to create the two bullet cavities, and the sprue plate operates smoothly. The included handles are simple, yet they offer a good grip that feels secure even with the heat involved. They attach securely, and their open design allows for good air circulation, keeping them from becoming excessively hot during prolonged use.

Ergonomically, the mold is comfortable enough for extended casting sessions. The weight, while not insignificant, is manageable. The handles are positioned such that they allow for a natural grip and easy manipulation of the mold, whether tilting it to pour or swinging the sprue cutter. The flat nose design of the bullet is also a practical ergonomic consideration, as it makes the bullets easier to handle and load into a variety of firearms without damage. There’s no significant learning curve; it functions exactly as you’d expect a well-made mold to.

Durability & Maintenance

In terms of durability, this Lee mold is built to last under normal reloading conditions. The aluminum alloy is resistant to corrosion and will not rust like iron molds can. Given that it’s a double-cavity design, there are fewer moving parts to wear out compared to some more complex molds. With proper care, it should provide many years of reliable service.

Maintenance is straightforward. A light application of mold release or diluted dish soap can be used on the cavities to ensure easy bullet separation and prevent lead buildup. Regular cleaning with a soft brush after each casting session will keep the cavities pristine. There are no obvious weak points; the sprue plate mechanism is robust, and the mold halves are tightly fitted. Potential concerns might arise from dropping the mold, as aluminum can dent, but even then, minor dents are often easily addressed with careful filing or sanding.

Accessories and Customization Options

The most significant accessory included with the Lee Double Cavity Mold .45-70 450gr W/handles are the handles themselves. These are often sold separately for other brands and significantly enhance the usability and safety of the mold. Beyond the handles, this mold is largely self-contained for its primary purpose.

Customization options for this specific mold are limited, as it’s designed to produce one particular bullet profile: a 450 grain Flat Nose in .45-70 Government. If you require different bullet weights or designs (e.g., hollow points, gas checks, or different nose profiles), you would need to purchase separate molds. However, its compatibility with standard sizing dies and lubers from various manufacturers means that once the bullets are cast, they can be easily processed with existing reloading equipment. The simplicity of its design is also its strength; it doesn’t require proprietary accessories.
