Breaking Down My First Experience with the Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl
The allure of casting your own bullets for a classic cartridge like the .45-70 Government is a powerful draw for any serious handloader. My journey led me to the Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl, a tool promising simplicity and efficiency for this iconic round. I was looking to replace a worn-out, generic mold and sought something that offered consistent performance for my Marlin 1895. Considering the price point, this Lee offering stood out against more expensive, multi-cavity options that felt like overkill for my modest needs. My initial impression upon unboxing was one of sturdy, no-nonsense functionality; the aluminum construction felt robust, and the wooden handles offered a pleasant tactile experience, a far cry from bare metal.
My previous mold, while functional, had begun to produce inconsistent results, and the idea of a dedicated hollow-base design for the .45-70 felt like a step towards optimizing my reloads. I’d glanced at some other brands, but the reputation Lee has for making accessible reloading tools, combined with the specific features of this mold, made it the clear frontrunner. My immediate feeling was one of quiet satisfaction, a sense that this tool would perform its intended job without fuss.
Real-World Testing: Putting Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl to the Test
First Use Experience
My initial testing of this hollow-base mold took place on my dedicated reloading bench, a space that has seen countless hours and a variety of reloading tools. I paired it with a standard Lee Pro 420 ladle and my trusted lead pot, setting up for a session of casting .45-70 bullets. The mold heats up remarkably quickly, a testament to its aluminum construction.
This rapid heat cycling meant I was casting good bullets within about fifteen minutes of starting the melt, a much shorter warm-up period than I’ve experienced with older steel molds. The Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl proved incredibly intuitive to use; the single cavity design simplifies the process, and the alignment pins felt precise. The only minor surprise was the specific temperature window required for optimal fill of the hollow base, but this was easily dialed in with a few test casts.
Extended Use & Reliability
After several months and hundreds of bullets cast, this Lee mold continues to impress with its consistent performance. It has become my go-to for .45-70 ammunition, and I’ve yet to encounter any significant wear or tear on the mold itself.
The aluminum body shows no signs of pitting or corrosion, and the CNC-machined cavities remain clean and well-defined. Maintenance is refreshingly simple: a quick wipe-down with a soft cloth after each casting session keeps it in top condition, and a light application of mold release wax is all that’s needed for storage. Compared to my previous experiences with cheaper, rougher molds, this single-cavity unit offers a noticeable improvement in both ease of use and bullet consistency, easily justifying its price.
Breaking Down the Features of Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl
Specifications
This Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl is crafted from durable aluminum, a material chosen for its excellent heat transfer properties. This allows the mold to heat up and cool down much faster than traditional iron or steel molds, significantly speeding up the casting process. The mold features a single cavity designed to produce bullets weighing approximately 405 grains, a classic weight for the .45-70 Government cartridge.
The projectile caliber is specifically machined to .459″, ensuring a proper fit for most .45-70 firearms. It boasts a hollow base design, which is crucial for achieving good expansion at lower velocities or for use in firearms with slightly oversized bores. The mold comes complete with wood handles, offering a comfortable and insulated grip during casting operations.
Performance & Functionality
The primary job of this mold is to produce consistent, well-formed bullets, and it excels at this. The 405-grain hollow-base design is particularly effective for the .45-70, as it allows the base of the bullet to expand and seal the bore even at moderate velocities, enhancing accuracy and reducing leading.
The single cavity design, while slower than multi-cavity options, offers exceptional simplicity and reduces the likelihood of casting errors. The CNC machining ensures precise dimensions, leading to a high degree of uniformity from bullet to bullet. Its main strength lies in its ability to cast expansion-friendly bullets easily and reliably for this powerful lever-action cartridge.
Design & Ergonomics
Lee has opted for a practical, no-frills design with this mold, focusing on function over aesthetics. The aluminum construction is lightweight and efficient, while the wood handles provide a secure and comfortable grip, minimizing heat transfer to the caster’s hands.
The single cavity layout is straightforward, making it easy to manage the pouring and ejection process. The alignment of the mold halves is precise, ensuring clean parting lines on the bullets. Even with extended casting sessions, the ergonomic handles prevent hand fatigue, making it a pleasure to use.
Durability & Maintenance
Given its aluminum construction and simple design, the Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl is built for longevity. Aluminum is naturally resistant to rust, and the CNC machining creates a smooth surface that resists lead buildup.
Regular maintenance involves cleaning out any residual lead or flux after casting and a light application of mold release. Stored properly in a dry environment, this mold should provide decades of reliable service for the avid handloader. The lack of intricate moving parts or delicate coatings means there are few points of failure to worry about.
Accessories and Customization Options
This particular offering comes with wood handles, which are a necessary component for safe operation and are considered part of the core product. No additional accessories, such as sprue cutters or aligning pins beyond what’s integrated into the mold itself, are typically included.
While this is a single-cavity mold, Lee does offer other multi-cavity versions for the .45-70, and their molds are generally designed to be compatible with their own casting equipment, such as their lead furnaces and ladles. There are no user-replaceable parts to speak of on the mold itself, beyond ensuring the handles are securely attached.

Who Should Buy Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl?
This mold is an exceptional choice for the handloader who specializes in the .45-70 Government cartridge and prioritizes performance over sheer volume. It’s perfect for the shooter who enjoys the process of reloading and wants to craft bullets specifically designed for lever-action rifles and potential hunting applications where controlled expansion is desired.
