Lee .38 Caliber Six Cavity Mold Review

The Final Word on the Lee .38 Caliber Six Cavity Mold

For any reloader serious about efficiency and consistency in their .38 Special, .38 Colt NP, or .357 Magnum ammunition, the Lee .38 Caliber Six Cavity Mold emerges as a compelling tool. This isn’t just another piece of reloading equipment; it’s an investment in streamlining the often time-consuming process of bullet casting. My journey to this particular mold was driven by a need to increase my output for practice rounds without sacrificing the quality that underpins reliable ammunition. My previous single-cavity mold, while adequate for initial experimentation, simply couldn’t keep pace with my growing demand for range time.

Upon arrival, the mold presented itself with a straightforward, utilitarian design. The rust-resistant aluminum construction immediately felt like a practical choice, promising longevity and ease of maintenance. It lacks the heft of iron or steel molds, suggesting a quicker heat cycle, which is a key factor in efficient casting sessions. I’d briefly considered a manual indexing multi-cavity mold from a competitor, but the promise of Lee’s established reputation for value and their no-frills approach to design ultimately steered me toward this six-cavity option. My initial impression was one of pragmatic expectation; this tool looked ready to work, not to impress with ornate flourishes.

Real-World Testing: Putting Lee .38 Caliber Six Cavity Mold to the Test

First Use Experience

My initial testing of the Lee .38 Caliber Six Cavity Mold took place on my dedicated reloading bench, a space accustomed to the hum of case tumblers and the clatter of resizing dies. I was keen to see how quickly the aluminum would heat and maintain its temperature, a crucial element for consistent bullet fill. I paired it with my standard Lyman lead melter and a thermometer for precise temperature monitoring.

The performance was, frankly, impressive for a first run. After the initial heat-up period, the mold achieved a steady casting temperature within what felt like minutes, significantly faster than my old single-cavity iron mold. The six-cavity configuration truly transformed the process, allowing me to produce a batch of usable bullets in a fraction of the time. There was a slight learning curve to managing the pouring and opening sequence for all six cavities simultaneously, but it was intuitive enough that after about ten casts, I was flowing smoothly.

The biggest surprise was the consistency of fill across all six cavities right out of the gate. I had anticipated a few “frogs” or incomplete fills, especially with the initial heat cycling, but the round nose bullet design seemed to fill cleanly from the start. No major issues or quirks presented themselves; it simply did what it was designed to do, efficiently and effectively.

Extended Use & Reliability

After several months of consistent use, pouring well over a thousand bullets, this mold has become an indispensable part of my reloading process. It’s become my go-to for producing bulk practice ammunition for my revolvers and lever-action rifle chambered in .38 Special. The mold has held up remarkably well to daily bench work, including the occasional bump against other equipment.

There are absolutely no visible signs of wear and tear, no cracks, and the aluminum shows no degradation. The precise alignment of the two mold halves has remained perfect, ensuring clean parting lines on the cast bullets. Maintenance is a breeze; a quick wipe-down with a soft cloth and a touch of mold release spray after each casting session is all that’s needed. I’ve learned to be mindful of not overheating the aluminum excessively, as this can sometimes lead to slight shrinkage issues, though it hasn’t been a significant problem.

Compared to my previous experiences with single-cavity molds, this six-cavity unit is a revelation. It significantly reduces the overall time spent casting, allowing me to focus on other aspects of reloading like sizing, priming, and powder charging. While it might not possess the aesthetic appeal of some high-end, custom molds, its practical reliability and output far outweigh any perceived shortcomings.

Breaking Down the Features of Lee .38 Caliber Six Cavity Mold

Specifications

The Lee .38 Caliber Six Cavity Mold is a meticulously designed piece of equipment for the serious handloader. At its core, it boasts a six-cavity design, a significant upgrade over single or double-cavity molds, allowing for vastly increased production rates. The mold itself is crafted from rust-resistant aluminum, a material chosen for its excellent heat transfer properties and lighter weight compared to traditional iron or steel.

This aluminum construction means the mold heats up faster and cools down quicker between casts, translating directly to more efficient casting sessions. Each cavity is designed to produce a 150 grain round nose (RN) bullet, a common and versatile weight for .38 Special and .357 Magnum loads, suitable for general target shooting and plinking. The overall bullet length is specified as .643 inches, with a distance from crimp groove to the nose of the bullet of .288 inches. These precise dimensions are critical for ensuring proper chamber fit and feeding in firearms. The mold comes without handles, a common Lee practice, allowing users to attach their preferred sprue cutter and handles for personalized ergonomics.

Performance & Functionality

The primary function of this mold is to cast consistent, well-formed bullets, and in this regard, the Lee .38 Caliber Six Cavity Mold excels. Its most notable strength is its high production rate. Casting six bullets at a time means that for every pour, I’m getting six projectiles ready for the next stage of reloading, drastically cutting down the overall time commitment.

The uniformity of the cast bullets is consistently good. Once the mold is up to temperature, each cavity produces a nearly identical bullet, minimizing the need for extensive sorting. The 150 grain weight is particularly useful, providing a good balance of accuracy and mild recoil for .38 Special. The round nose profile is ideal for smooth feeding in revolvers and lever-action firearms. A minor weakness, if one can call it that, is the reliance on user-provided handles and sprue cutter. While this offers customization, it also means an additional purchase or use of existing compatible tools to get started.

Design & Ergonomics

The design of this six-cavity mold is driven by pure functionality. The rust-resistant aluminum construction is not only practical for heat management but also keeps the overall weight manageable, especially when it’s at temperature and filled with molten lead. The precision-machined cavities ensure that each bullet cast will have consistent dimensions, which is paramount for reloading accuracy.

While the mold itself doesn’t have built-in handles, the ergonomic consideration comes into play when paired with aftermarket accessories. The split design with alignment pins ensures that the mold closes perfectly every time, preventing lead sprue flash and ensuring consistent bullet bases. The channels for venting allow for easy release of gases, contributing to cleaner bullet fills. It’s a no-nonsense design that prioritizes performance over aesthetics, which is exactly what a tool like this should do.

Durability & Maintenance

The durability of this aluminum mold is, in my experience, excellent for its intended purpose. The rust-resistant aluminum alloy is robust enough to withstand the temperatures involved in lead casting and the rigors of repeated opening and closing. I anticipate this mold will last for many thousands of casts, provided it’s treated with basic care.

Maintenance is incredibly simple. A quick wipe-down with a soft cloth and a mold release agent after each casting session keeps it clean and ready for the next use. I occasionally use a soft brass brush to gently clean any stubborn lead residue from the sprue plate area, but this is infrequent. There are no complex parts to break or wear out. The main point of care is to avoid dropping it on a hard surface, as aluminum, while durable, can dent or deform if subjected to significant impact.

Accessories and Customization Options

The Lee .38 Caliber Six Cavity Mold typically comes as the mold block and sprue plate, requiring the user to provide their own casting handles and sprue cutter. Lee offers a range of compatible handles, such as their traditional wooden-handled designs, which offer good insulation and grip. Investing in a quality sprue cutter is also recommended for clean separation of the bullets from the sprue.

While the mold itself is fixed in its design for a 150 grain round nose bullet, the real customization comes with the finishing processes applied to the cast bullets. Reloaders can choose to size these bullets to various diameters depending on their firearm’s specific needs, tumble lube them, or apply traditional bullet lubes. The consistent dimensions from this mold make it an excellent base for a variety of finishing techniques.
