Lee Double Cavity Mold .312-155-2r W/handles Review

Hands-On with the Lee Double Cavity Mold .312-155-2r W/handles

The world of reloading can often feel like navigating a dense forest, with countless tools and techniques to master. For many, the journey begins with casting their own bullets, a path that offers significant cost savings and a deeper connection to the shooting sports. It was in this pursuit that I found myself drawn to the Lee Double Cavity Mold .312-155-2r W/handles, a seemingly simple piece of equipment that promised to unlock a new level of self-sufficiency at the reloading bench. My specific need arose from a desire to cast bullets for a particular rifle caliber, and after researching various options, this particular mold from Lee seemed to strike a balance between affordability and functionality.

My initial impression upon unboxing was one of pragmatic simplicity. The mold itself is crafted from aluminum, a material known for its rapid heat conductivity, which is crucial for efficient casting. The included handles felt sturdy enough, though perhaps not as finely finished as one might find on more expensive, premium molds. I had considered a competitor’s steel mold, which offered more cavities but at a considerably higher price point, and a cheaper, unbranded aluminum mold that had mixed reviews regarding its accuracy and durability. This Lee offering seemed to hit a sweet spot, offering a reputable brand and a well-established design at an accessible price. My immediate feeling was one of cautious optimism; it looked like a tool that would get the job done without unnecessary fuss.

Real-World Testing: Putting Lee Double Cavity Mold .312-155-2r W/handles to the Test

First Use Experience

My initial foray with the Lee Double Cavity Mold .312-155-2r W/handles took place on my workbench, a space familiar with the smell of hot lead and the clinking of brass. The setup was straightforward, involving preheating the mold on my casting pot and ensuring proper lubrication of the sprue plate and alignment pins. The mold heated up quickly, as expected from its aluminum construction. My first few casts were a bit tentative, focusing on getting the temperature of both the alloy and the mold just right.

The mold performed admirably from the outset, producing consistently sized bullets with minimal effort. I was particularly impressed with how quickly it could be brought up to optimal casting temperature and how well it retained that heat through a casting session. Even with repeated cycles of opening, pouring, and closing, the mold maintained a stable thermal equilibrium, which is key to consistent bullet weights. There were no significant surprises, though like any new mold, a brief adjustment period was needed to dial in the precise alloy temperature for the best fill-out.

Extended Use & Reliability

After several weeks of regular casting sessions, the Lee Double Cavity Mold .312-155-2r W/handles has become a workhorse in my reloading setup. I’ve used it for batches ranging from a hundred to several hundred bullets, and it has held up remarkably well. The aluminum alloy shows minimal signs of wear, with no noticeable pitting or damage to the mold cavities.

The 2-cavity design, while not the fastest in terms of sheer output, has proven to be incredibly reliable. Each bullet drops from the cavity with a clean release, and the alignment pins have remained tight, ensuring perfect roundness consistently. Maintenance is a breeze; a quick wipe-down with a brass brush after cooling and a light application of mold release agent is all that’s needed to keep it in top condition. Compared to some older, cast-iron molds I’ve used in the past that required more meticulous cleaning and conditioning, this aluminum mold is a pleasure to maintain.

Breaking Down the Features of Lee Double Cavity Mold .312-155-2r W/handles

Specifications

The Lee Double Cavity Mold .312-155-2r W/handles is designed with precision and efficiency in mind for the reloading enthusiast. Its core construction is lightweight aluminum, which is a significant advantage for heat transfer. This material ensures that the mold heats up quickly and cools down efficiently between shots, a crucial factor for consistent bullet casting.

It features a 2-cavity design, allowing for the production of two bullets with each cycle of the sprue plate. The mold is specified for a .312 Caliber projectile, with each bullet designed to weigh approximately 155 grain. The Round Nose (RN) profile is a classic and versatile bullet shape. The mold comes complete with handles, making it ready for immediate use upon arrival.

Performance & Functionality

The primary function of this mold is to cast consistent, usable bullets, and it excels at this task. The .312 Caliber dimension is accurate, producing bullets that drop at or very near the specified diameter, which is critical for proper fit in the firearm barrel. The 155 grain weight is also remarkably consistent from one casting session to the next, provided the alloy and mold temperatures are maintained correctly.

The mold’s greatest strength lies in its ability to produce repeatable results. The Round Nose design, a common choice for many rifle applications, ensures good feeding characteristics in a variety of firearms. A slight weakness, inherent to most aluminum molds, is their susceptibility to slight damage if mishandled; however, with proper care, this is rarely an issue.

Design & Ergonomics

Lee has opted for a practical, no-nonsense design with this mold. The aluminum construction is not only functional for heat transfer but also contributes to the overall lightness of the tool. The included handles are functional and provide a decent grip, though they are not cushioned or ergonomically sculpted for extended periods of high-volume casting.

The mold blocks hinge smoothly, and the sprue plate aligns well, which is essential for preventing lead overflow and ensuring clean bullet separation. The overall feel is one of a tool designed for utility rather than luxury. The pre-crimped hinge blocks are a thoughtful touch that helps maintain alignment, contributing to the consistency of the cast bullets.

Durability & Maintenance

For an aluminum mold, the Lee Double Cavity Mold .312-155-2r W/handles offers commendable durability. It’s designed for repeated use and will last for thousands of casts if treated with basic care. The primary concern with aluminum molds is preventing them from being scratched or dented, which can affect the mold’s ability to seal properly and create perfect bullets.

Maintenance is straightforward and minimal. After each casting session, it’s recommended to let the mold cool completely, then brush out any residual lead or flux. A light application of a good quality mold release agent before casting helps ensure smooth bullet release and prolongs the life of the mold’s surface. There are no complex parts to maintain, making it an ideal choice for beginners and experienced casters alike.

Accessories and Customization Options

The Lee Double Cavity Mold .312-155-2r W/handles comes as a complete kit, including the mold blocks and sturdy handles. Lee also typically offers a sprue cutter for sale separately, though this mold is designed to be used with a universal sprue plate that can be attached.

While this specific mold does not offer direct customization in terms of bullet profile or weight (as it’s a fixed design), Lee offers a vast range of other molds with different cavity counts, weights, and bullet shapes. The key accessory for this mold is a good lubricant and sizing station, as the cast bullets will need to be sized and lubricated for optimal performance in most firearms. A casting pot and lead alloy are, of course, fundamental to using this mold.

Pros and Cons of Lee Double Cavity Mold .312-155-2r W/handles

Who Should Buy Lee Double Cavity Mold .312-155-2r W/handles?

This mold is an ideal starting point for any shooter looking to venture into casting their own bullets for rifles chambered in calibers that utilize a .312 Caliber projectile, such as the 7.62x39mm. It’s perfect for the budget-conscious reloader or someone who doesn’t need to produce thousands of bullets at a time but wants the satisfaction and cost savings of DIY casting. Hobbyists and tinkerers who enjoy the process of developing their own ammunition will find this mold a rewarding tool.

Those who require extremely high-volume production might want to consider a mold with more cavities, though this would come at a significantly higher cost. Individuals who are prone to rough handling of their equipment might also want to consider a steel mold for added robustness. A must-have accessory to pair with this mold is a good lubricant and sizing kit, as well as a reliable lead alloy and a casting pot.
