Real-World Testing: Putting Lee Six Cavity Mold .358 158gr-rf No Handles to the Test

First Use Experience

My initial testing commenced on my reloading bench, a space that has seen countless tools come and go over the years. The Lee Six Cavity Mold .358 158gr-rf No Handles requires the addition of mold handles, which I had purchased separately. After a brief acclimation period to ensure proper alignment and temperature, I began casting. The aluminum blocks are substantial, and the overall feel is solid, even without the handles attached.

The process of shimming the mold block halves, as recommended, was straightforward, using thin aluminum shims and a few firm taps from a hammer to ensure a precise fit. Casting in batches of fifty projectiles proved noticeably faster than with my previous single-cavity setup. I did notice a slight learning curve in achieving consistent fill-out across all six cavities on the very first pour, but this was quickly resolved with minor adjustments to the melt temperature and pour rate.

One minor quirk I encountered was the initial stickiness of the sprue plate. It required a bit more effort to slide and pivot than I anticipated, but this eased up considerably after a few cycles. For a first-time use, the experience was largely positive, yielding a batch of usable projectiles with minimal rejection.

Extended Use & Reliability

After several weeks of consistent use, processing hundreds of lead ingots through this mold, its performance has remained remarkably stable. The Lee Six Cavity Mold .358 158gr-rf No Handles has become a workhorse on my bench. I’ve subjected it to repeated heat cycles, with casting sessions lasting for several hours at a time, and it continues to produce consistent results.

Durability has been impressive. Despite being aluminum, which can be prone to galling, the mold cavities show no signs of significant wear or pitting. The hard-anodized sprue plate has held up well, resisting scratching from the sprue cutter. Maintenance is also refreshingly simple; a quick wipe-down with a soft cloth and occasional application of mold release agent is all that’s needed to keep it in optimal condition.

When compared to other multi-cavity molds I’ve encountered, this Lee offering strikes an excellent balance between cost and capability. While some higher-end molds might offer slightly tighter tolerances out of the box, the difference is often marginal and can be addressed with proper setup. For its price point, the reliability and output of this mold are exceptional.

Breaking Down the Features of Lee Six Cavity Mold .358 158gr-rf No Handles

Specifications

The Lee Six Cavity Mold .358 158gr-rf No Handles is a precision-engineered tool designed for high-volume bullet casting. It features six individual cavities, each precisely machined to produce a 158-grain round flat nose (RFN) bullet. The mold itself is constructed from durable aluminum blocks, chosen for its excellent heat transfer properties and resistance to rust.

These blocks are designed to accept standard Lee mold handles, which are sold separately, allowing for a comfortable and secure grip during casting operations. The hard anodized sprue plate is a key component, featuring a cam-operated design for smooth actuation and enhanced durability. It’s secured with steel spring washers, ensuring consistent tension and alignment.

The sprue plate’s design allows it to slide out and pivot up, exposing the casting cavity and facilitating easy removal of the sprue. Hardened steel pins are integrated into the design to lay flat on the sprue ring for precise cuts. Permanently sealed cavity plugs are reinforced with hardened steel shaft bushings for added stability and longevity. The .358″ diameter is ideal for a variety of .38 Special and .357 Magnum handloads.

Performance & Functionality

The primary function of the Lee Six Cavity Mold .358 158gr-rf No Handles is to cast accurate and consistent bullets at an accelerated rate, and it performs this task admirably. The six-cavity design is the standout feature, allowing for significantly higher production volumes compared to single or double-cavity molds. This translates directly into saving valuable time for reloaders who prepare ammunition in quantity for practice, competition, or defense.

The 158-grain RFN profile is a tried-and-true design, offering a good balance of weight and bearing surface for many .38 Special and .357 Magnum loads. It generally provides excellent accuracy and feeding reliability in most firearms chambered for these calibers. The consistency of the cast bullets, once the mold is properly heated and aligned, is a testament to the precision of the machining.

A minor weakness could be observed in the need for precise temperature control and proper pouring technique to ensure all cavities fill out perfectly on every cycle. However, this is characteristic of most high-production casting molds, rather than a fault of this specific Lee model. Once mastered, the output is impressive, yielding round and well-formed projectiles ready for sizing and loading.

Design & Ergonomics

The design of this Lee mold prioritizes functionality and efficiency. Its construction from aluminum blocks makes it relatively lightweight for its size, which is a benefit during extended casting sessions. The hard anodized sprue plate and the robust spring mechanism are well-engineered to withstand the rigors of repeated use without becoming loose or imprecise.

Ergonomically, the mold is designed to be held and operated with separate mold handles. The shape of the mold blocks themselves provides ample surface area for gripping when positioning or aligning it. The mechanism for opening and closing the sprue plate is smooth and intuitive once you get a feel for it.

The inclusion of features like the hardened steel shaft bushings for the cavity plugs speaks to Lee’s commitment to creating durable products. While not as aesthetically refined as some premium molds, the straightforward, utilitarian design ensures it is easy to understand and operate, even for those new to multi-cavity casting.

Durability & Maintenance

This six-cavity mold is built for endurance and consistent performance over time. The use of aluminum blocks provides a good balance of heat conduction and material toughness. The hard anodized sprue plate is particularly noteworthy for its resistance to wear and galling, which are common issues with lesser-quality sprue plates that come into contact with molten lead repeatedly.

Maintenance is straightforward, requiring minimal effort to keep it in optimal working condition. After each casting session, a light cleaning with a soft brush to remove any residual lead or flux is usually sufficient. For long-term care, applying a thin coat of mold release agent or specialized mold lubricant can help preserve the mold surfaces and ensure smooth operation.

I have not encountered any significant failure points during my testing. The steel spring washers maintain their tension, and the cam mechanism on the sprue plate operates without binding. For a tool intended for high-volume production, the durability of this Lee mold appears to be excellent.

Accessories and Customization Options

The Lee Six Cavity Mold .358 158gr-rf No Handles comes as a core component, with a significant emphasis on what is not included. Most notably, mold handles are sold separately. While this allows users to choose their preferred style of handles, it’s an essential consideration for anyone purchasing this mold.

Beyond the handles, there are no other included accessories. However, the mold is designed to be compatible with standard reloading tools and accessories. This includes a sprue cutter (often integrated into the handles or a separate tool), a lead pot, and a thermometer for precise temperature control. Sizing and lubing dies, specific to the .358″ diameter, are also necessary for post-casting processing.

The inherent “customization” of this mold lies in its design for a specific bullet profile – the 158-grain RFN. While you can’t change the bullet shape itself without a different mold, the choice of lead alloy and the subsequent sizing/lubrication process offer avenues for tailoring the finished projectile to specific firearm tolerances and performance requirements.
