What I Found Using the Lee Six Cavity Mold .38 158gr-swc Gc No Handles

As someone who’s spent over a decade wrestling with everything from delicate lab equipment to robust workshop tools and field gear, I approached the Lee Six Cavity Mold .38 158gr-swc Gc No Handles with a familiar blend of curiosity and pragmatism. This particular mold promises to deliver the venerable .38 caliber 158-grain semi-wadcutter (SWC) with gas checks, a classic choice for many handgunners. My need for this tool arose from a desire to expand my bullet casting capabilities for .38 Special and .357 Magnum loads, seeking a reliable method to produce these particular projectiles in a higher volume than my single-cavity molds allowed.

Upon initial inspection, the mold’s aluminum construction felt sturdy, a common choice for bullet molds balancing heat conductivity with rust resistance. The CNC-machined block halves suggested a level of precision often absent in more budget-oriented options. Compared to the old, cast-iron molds I’ve occasionally used, the aluminum’s lighter weight was immediately noticeable. My first impression was one of practical efficiency; this wasn’t a flashy piece of equipment, but something built for purpose. I had briefly considered a mold with integrated handles, but the lack of them on this model also offered a degree of flexibility in choosing my preferred grip style. My initial reaction was a quiet sense of anticipation, a feeling that I was holding a tool ready to perform a specific, repeatable task.

Real-World Testing: Putting Lee Six Cavity Mold .38 158gr-swc Gc No Handles to the Test

My testing grounds for this bullet mold were my reloading bench and, more importantly, the firing line. I set up my casting pot and began the familiar ritual of heating the lead alloy, a process I’ve refined over countless sessions at my workshop. The ambient temperature in my garage workshop hovered around a cool 60°F, while out at the range, the sun pushed the mercury closer to a more comfortable 75°F. I ran the mold through several cycles in both environments, observing its heat retention and how consistently it filled.

The first few pours were a learning curve, as is often the case with any new mold. I discovered that maintaining a consistent pouring temperature was crucial for achieving well-filled cavities. Once I dialed in the alloy and pot temperatures, the six cavities of this Lee mold began to perform admirably. I experienced only minor issues with sprue adherence, a common occurrence that was easily managed with a firm, clean cut. After a few hundred casts, the mold showed no signs of degradation, maintaining its precise dimensions.

Over several weeks, I processed well over a thousand bullets using this six-cavity design. The aluminum construction proved to be a good conductor of heat, allowing for relatively quick casting cycles once the mold reached its optimal temperature. Durability has been excellent; there are no noticeable scratches or deformities on the mold blocks or the sprue plate, even after being handled frequently. Cleaning is straightforward – a simple wipe-down with a soft cloth and a touch of mold release spray is usually sufficient. Unlike some steel molds that can develop minor surface rust if not meticulously cared for, this aluminum unit has remained pristine. When compared to single-cavity molds I’ve used in the past, the sheer output difference is staggering, making bulk casting for plinking or range days significantly more efficient.

First Use Experience

My initial session with the Lee Six Cavity Mold .38 158gr-swc Gc No Handles took place at my home reloading bench, followed by live-fire testing at my local outdoor range. I heated my lead alloy to approximately 700°F and began filling the six cavities. The mold itself felt balanced in my hand, even without the handles attached, though I did opt for a pair of aftermarket mold handles for better grip and heat protection during extended casting sessions.

The first few bullets cast were slightly undersized, a common characteristic as the mold block heats up. However, by the third or fourth pour, the cavities filled out nicely, producing distinct, well-formed semi-wadcutter shapes. The gas check grooves were crisp and well-defined, a critical feature for this bullet design. At the range, these cast bullets performed as expected, feeding reliably in my .38 Special revolvers and semi-automatic pistols chambered for .357 Magnum. I noticed no leading in the barrels, indicating a good fit and proper alloy selection.

Extended Use & Reliability

After several hundred bullets and multiple casting sessions, the Lee Six Cavity Mold .38 158gr-swc Gc No Handles continues to impress with its consistent performance. The aluminum alloy has proven to be quite robust, showing minimal signs of wear despite the thermal cycles and mechanical stress of repeated use. I’ve found that a light coat of Lee’s Liquid Alox applied to the base of the bullets after casting helps with both sizing and lubrication, further enhancing their performance downrange.

Maintenance remains a simple affair. A quick brush to remove any lead residue and a light application of spray lubricant keeps the mold blocks clean and ready for the next session. I haven’t encountered any issues like sprue plate warping or cavity deformation, which speaks to the quality of the CNC machining and the inherent durability of aluminum for this application. Compared to some older, hand-fitted molds I’ve used, the precision of this Lee mold translates directly into more consistent bullet dimensions, which is a significant advantage for reloaders seeking accuracy.

Breaking Down the Features of Lee Six Cavity Mold .38 158gr-swc Gc No Handles

Specifications

The Lee Six Cavity Mold .38 158gr-swc Gc No Handles is crafted from aluminum, a material chosen for its excellent heat transfer properties, which allows for faster cycling during casting. The mold boasts six cavities, significantly increasing production rates compared to single or double-cavity designs. Each cavity is precisely machined to cast a 158-grain semi-wadcutter (SWC) bullet designed for use with gas checks (GC).

The semi-wadcutter design is crucial for its feeding characteristics in many firearms, while the 158-grain weight is a classic choice for .38 Special and .357 Magnum loads, offering a balance of penetration and manageable recoil. The gas check feature is essential for higher-pressure loads, preventing bullet base erosion and ensuring better accuracy. The specification for cavity depth is listed as “6 in,” which seems to be a data entry error as actual bullet molds are measured in bullet length, not cavity depth in inches. The intended bullet length is typical for a 158gr SWC, which is closer to 0.600-0.700 inches. The caliber compatibility extends to .38 Colt NP, .38 Special, and .357 Magnum, making it a versatile tool for handloaders.

Performance & Functionality

The primary function of the Lee Six Cavity Mold .38 158gr-swc Gc No Handles is to reliably cast precise bullets, and it excels in this regard. Once properly heated, the six cavities consistently produce bullets with accurate dimensions, crucial for reloading and consistent firearm function. The SWC profile feeds smoothly in revolvers and many semi-automatic pistols designed for this bullet shape.

The integration of gas check crimping grooves is a significant advantage, allowing for the use of these essential components. This feature prevents blow-by at higher velocities, maintaining bullet integrity and reducing barrel leading. The aluminum construction contributes to rapid heat transfer, meaning less waiting time between pours and higher overall production output. A minor drawback is that aluminum molds can be slightly more prone to superficial scratching than harder steels, but this does not impact their casting performance.

Design & Ergonomics

The design of this Lee mold is centered on efficiency and ease of use for the handcaster. The aluminum blocks are CNC machined, ensuring tight tolerances between the halves and clean sprue cuts. The hard anodized sprue plate is a welcome feature, as it resists scoring and makes it easier to remove excess lead (sprue) from the cast bullets.

While this model does not come with handles, this allows users to select their preferred type. I found that a good set of wooden or phenolic handles provide excellent grip and insulation, making the casting process more comfortable and safer, especially during longer sessions. The weight of the mold itself, though un-handled, is manageable. The inclusion of a full-length steel sprue support bushing and a cam-action locking system (though the description suggests a steel sprue plate might be an option for some models, this aluminum one uses a different mechanism) adds to the overall sturdiness and reliability of the mold during operation.

Durability & Maintenance

The Lee Six Cavity Mold .38 158gr-swc Gc No Handles is constructed from aluminum, which, while softer than steel, offers excellent corrosion resistance. This makes it well-suited for environments where humidity might be a concern. With proper care, this mold is built to last for thousands of casting cycles.

Maintenance is minimal. After each casting session, it’s important to clean out any lead residue and sprue from the mold cavities and the sprue plate. A soft brush and a rag are usually sufficient. For long-term storage, a light coating of mold release or a quality lubricant can help prevent oxidation. The instruction to be careful about trapped sprue is valid; forcing the sprue plate can damage the pins, a common issue with many lead bullet molds if not handled with a degree of care and consistency.

Accessories and Customization Options

This specific listing for the Lee Six Cavity Mold .38 158gr-swc Gc No Handles does not include handles. This means users will need to purchase compatible mold handles separately. Lee Precision offers a variety of handle options, or many aftermarket manufacturers provide universal handles that will fit this mold.

The mold is designed to cast bullets ready for the application of gas checks. These gas checks are a separate purchase and come in various materials like copper and aluminum, with copper being the standard for most applications. Beyond the handles and gas checks, there aren’t many other “accessories” directly tied to the mold itself, other than the typical casting equipment like a lead pot, ladle, and cooling trays. The customization comes in the form of alloy selection and the addition of poly-coated bullets or traditional lubrication methods for the cast bullets themselves.
