Real-World Testing: Putting Lee Six Cavity Mold .38 105gr-swc No Handles to the Test

First Use Experience

My initial foray with this Lee mold took place on my dedicated reloading bench, a space familiar with the heat of lead and the tang of flux. The ambient temperature was a comfortable room temperature, and the lighting was steady, providing ideal conditions for a first casting run. I preheated the mold to its optimal casting temperature, ensuring the aluminum block was evenly warmed to prevent premature solidification.

The process of filling the six cavities was surprisingly fluid. Unlike some older molds I’ve encountered, this one seemed to heat up and cool down quite efficiently, allowing for a consistent casting rhythm. There were no immediate issues, no sticking bullets or significant fill problems, which was a welcome surprise. The CNC machining was evident from the crisp lines of the bullets, with the semi-wadcutter (SWC) nose profile coming out sharp and well-defined.

Extended Use & Reliability

Weeks of consistent use have followed that initial test, and this six-cavity mold has become a cornerstone of my .38 Special and .357 Magnum reloading. I’ve used it for everything from light target loads to heavier defensive rounds, and it has performed admirably across the board. The anodized aluminum spru plate has held up remarkably well, showing no signs of rust or significant wear, despite frequent contact with molten lead and occasional vigorous wiping.

Durability has been impressive. I’ve accidentally dropped a filled bullet, resulting in a minor ding on the nose but no structural damage to the mold itself. The aluminum blocks have resisted excessive wear, and the semi-wadcutter cavities continue to produce clean, consistent bullets with a weight averaging very close to the advertised 105 grains. Maintenance is straightforward; a quick wipe down with a soft cloth after casting, and a more thorough cleaning with a brass brush and mold release agent every few hundred rounds, keeps it in peak condition. Compared to some older, pitted molds I’ve used, this Lee unit feels far more resistant to the common degradation that plagues bullet casting equipment.

Breaking Down the Features of Lee Six Cavity Mold .38 105gr-swc No Handles

Specifications

The Lee Six Cavity Mold .38 105gr-swc No Handles is constructed from hard anodized aluminum, a material chosen for its excellent heat transfer properties and inherent resistance to corrosion and wear. This particular mold features six individual cavities, each designed to cast a 105-grain bullet with a Semi Wadcutter (SWC) profile. The mold block halves are CNC machined, a critical aspect that ensures high precision and uniformity in the final cast projectiles.

The aluminum spru plate is a key component, specifically chosen for its rust-resistant properties, making it ideal for the often humid conditions of a reloading room or workshop. The caliber compatibility is listed as .38 Colt NP, .38 Special, and .357 Magnum, offering versatility for shooters of these popular handgun cartridges. The weight of each cast bullet, approximately 105 grains, is well-suited for various applications, from economical practice rounds to more specialized loads.

The SWC design is characterized by its flat nose, which aids in feeding reliability in many handguns and creates a larger diameter hole upon impact compared to round nose bullets, often referred to as “cutting” a hole. This specific mold’s cavity depth is noted as 6 inches, which seems unusually deep for a handgun bullet mold; it’s likely a misprint in the source material and should be considered a standard depth for a 105gr SWC designed for .38/.357 cartridges. The absence of handles on this mold means the user must provide their own, often custom-fit, or utilize a mold-handling system.

Performance & Functionality

This Lee mold excels at its primary function: casting consistent, well-formed bullets in high volume. The six-cavity design significantly speeds up the casting process, allowing me to produce a substantial quantity of bullets in a single session, dramatically reducing the time spent at the lead pot. The 105-grain weight is a sweet spot for many .38 Special loads, offering a good balance between projectile mass and powder charge for economical yet effective shooting. The Semi Wadcutter (SWC) nose consistently casts with a sharp, well-defined edge, which is crucial for feeding reliability in revolvers and semi-automatic pistols designed to handle this bullet shape.

The CNC machining is clearly evident in the quality of the castings; there is minimal flashing, and the bullet bases are square and uniform. This leads to bullets that are not only aesthetically pleasing but also perform reliably when loaded and fired. I’ve found that bullets cast from this mold require very little sizing, often just a light touch-up, which further streamlines the reloading process. The primary strength of this mold lies in its efficiency and consistency, allowing reloaders to produce a high volume of quality bullets without excessive effort or cost.

Design & Ergonomics

The hard anodized aluminum construction of this mold is not merely for durability; it also plays a crucial role in its thermal dynamics. Aluminum heats up quickly and evenly, which is essential for achieving consistent fill and preventing cold shuts in the cast bullets. The anodized finish not only protects against corrosion but also provides a smoother surface that can aid in easier ejection of the cast bullets.

While this model comes without handles, this is a deliberate design choice that offers users flexibility. Many experienced casters prefer to fit their own custom handles or use specialized mold-handling equipment for better heat insulation and control. The CNC machined block halves ensure a precise fit, minimizing the potential for excessive lead leakage between the two halves. The SWC design itself, with its distinct flat nose, is a classic profile that integrates well into the overall functionality of the mold.

Durability & Maintenance

The inherent properties of hard anodized aluminum make this mold exceptionally durable for its intended purpose. Unlike softer alloys, it resists scratching and dings, and the anodization process creates a hardened surface layer that significantly increases its lifespan. After numerous casting sessions, the mold cavities remain sharp and well-defined, with no signs of pitting or erosion from repeated exposure to molten lead.

Maintenance is quite straightforward, mainly involving keeping the mold clean and properly lubricated. A quick wipe with a natural fiber cloth or a brass brush after each casting session removes any residual lead or flux. Applying a light coat of mold release agent or even a bit of Bore Snake lube to the mold surfaces before heating can help ensure easier bullet release and prolong the life of the mold by preventing lead buildup. The absence of handles on this specific model means there’s one less component to worry about breaking or becoming loose over time.

Accessories and Customization Options

As this is a mold without handles, the primary “accessory” the user must procure is a set of suitable mold handles. These can range from simple wooden handles to more sophisticated, heat-resistant aftermarket options. Many reloaders choose to fabricate their own custom handles from wood or other materials to achieve a personalized grip and optimal heat insulation.

The mold is designed for .38/.357 caliber handguns, specifically casting a 105-grain Semi Wadcutter (SWC) bullet. While the mold itself is fixed in its design, the type of lead alloy used can be considered a form of customization. Varying the alloy composition (e.g., adding tin for better flow or antimony for hardness) can slightly alter the final bullet properties, though the weight and general dimensions will remain consistent with the mold’s design. Compatibility with standard bullet sizers and lubers is, of course, assumed, as this is a standard cast bullet mold.
