Let’s Dive into Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl
The Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl is a tool for reloaders seeking to cast their own .45/70 bullets, specifically a 405-grain hollow base design. This mold is manufactured by Lee Precision, a name synonymous with affordable and reliable reloading equipment. Its single-cavity design and aluminum construction offer a unique approach to bullet casting.
My interest in this mold stemmed from a desire to enhance the accuracy and consistency of my .45/70 reloads. Commercial .45/70 ammunition can be expensive and sometimes lacks the specific characteristics I require for different shooting scenarios. I wanted more control over bullet weight, alloy composition, and overall performance; casting my own seemed like the ideal route.
Upon unboxing, the mold felt surprisingly lightweight, a characteristic of its aluminum construction. The included handles felt reasonably comfortable, and the overall build quality seemed adequate for the price point. The mold is CNC machined, so it is supposed to produce accurate bullets.
I considered molds from Lyman and RCBS, both reputable names in bullet casting. However, the Lee mold’s lower price and the hollow base design, which theoretically improves accuracy by obturating to fill the bore, ultimately swayed my decision. I was also intrigued by the faster heat-up and cool-down times touted for aluminum molds.
My first impression was cautiously optimistic. While the mold didn’t exude the robust feel of some steel molds, its lightweight design and hollow base feature intrigued me. I was eager to put it to the test and see if it could deliver accurate and consistent bullets.
Real-World Testing: Putting Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl to the Test
First Use Experience
I first tested the Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl at my home reloading bench, using a propane-fueled lead melting pot. The initial casting session took place in a well-ventilated area to manage fumes and ensure safety. I wanted to make sure to produce quality bullets right from the start.
The mold heated up quickly, as expected from aluminum. However, it also cooled down rapidly, which meant a slightly faster casting cycle, a benefit when producing a large batch. I experienced some initial difficulty getting perfectly filled-out bullets, likely due to my inexperience with aluminum molds and the specific alloy I was using.
The biggest initial issue was finning, or thin layers of lead forming at the mold parting lines. This required extra time for trimming and cleanup. After adjusting my casting technique and fluxing the lead more thoroughly, the quality of the bullets improved significantly.
Extended Use & Reliability
After several weeks of use, the Lee mold has proven to be relatively durable, although it requires a bit more care than steel or iron molds. The aluminum is softer and more prone to scratching, so gentle handling is crucial. A little care can make a big difference.
I haven’t noticed any significant wear and tear, but I’m careful to avoid excessive force when opening and closing the mold. The handles have remained secure, and the mold continues to produce consistent bullet weights. I ensure to keep the mold clean and lubed appropriately.
Maintenance is straightforward: I clean the mold with a soft brush after each casting session and occasionally apply a mold release agent to prevent sticking. Compared to my older iron molds, the Lee mold requires more frequent cleaning to prevent lead buildup. However, it is still a very usable mold.
Breaking Down the Features of Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl
Specifications
The Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl is specifically designed for casting .45/70 Government bullets. The bullet weight is nominally 405 grains, although this can vary slightly depending on the alloy used. It is important to stay within safe parameters.
The projectile caliber is listed as .459 Caliber, intended for use in .45/70 rifles with a .458″ bore diameter, allowing for proper obturation and accuracy. The mold itself is constructed from aluminum, with wood handles for heat insulation and comfortable grip. This allows for safer handling.
The mold is a single-cavity design, meaning it produces one bullet per casting cycle, which is slower than multi-cavity molds but potentially allows for greater precision. The bullet type is a Flat Nose (FN) with a Hollow Base (HB), a design intended to expand under pressure and improve accuracy. These bullets are great for target practice.
These specifications matter because they directly impact the bullet’s performance and suitability for different applications. The 405-grain weight is a classic .45/70 bullet weight, providing a good balance of range and stopping power. The hollow base aids in sealing the bore, especially with softer lead alloys.
Performance & Functionality
The Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl performs its job reasonably well, producing consistent bullet weights and dimensions once the casting technique is refined. Accuracy with these bullets, when properly loaded, is very good in my .45/70 rifle. These bullets can produce fantastic results.
The main strength of this mold is its affordability and the hollow base design, which can improve accuracy, especially in rifles with slightly oversized bores. The primary weakness is the single-cavity design, which makes casting large quantities of bullets time-consuming. It requires an extra effort to cast bullets.
It meets my expectations for a budget-friendly mold, providing a way to cast accurate .45/70 bullets at home. However, the slower casting rate and the need for careful handling are drawbacks that should be considered. You must handle with care.
Design & Ergonomics
The Lee mold’s design is simple and functional, prioritizing affordability over high-end materials. The aluminum construction keeps the weight down, making it easier to handle during extended casting sessions. Lighter materials are always better.
The wood handles provide adequate insulation, but they can become uncomfortable after prolonged use. There is a slight learning curve associated with casting with aluminum molds, particularly in managing the temperature and preventing finning. There is a bit of a learning curve.
Durability & Maintenance
The Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl should last for many years with proper care, although the aluminum is more susceptible to damage than steel or iron. Regular cleaning and lubrication are essential to prevent lead buildup and ensure smooth operation. Proper maintenance is key.
Repairs are generally limited to replacing the handles if they become damaged. However, the mold itself is relatively inexpensive to replace if it becomes unusable. The most important thing is to handle with care.
Accessories and Customization Options
The Lee Single Cavity Mold .45/70 405 Gr. Hollow Base Mold W/hdl does not come with any specific accessories beyond the included handles. Customization options are limited, as it’s a relatively simple tool. It would be difficult to modify the design.
It is compatible with standard lead melting pots, dippers, and other bullet casting accessories. However, there are no specific aftermarket upgrades designed specifically for this mold. There is nothing extra needed.
