The mold is precisely machined for a .379 caliber bullet, which is crucial for proper fit and function in .375 caliber firearms.
It casts a 250 grain bullet with a Round Nose (RN) profile, designated by the “250-rf” in its name. The mold itself is constructed from aluminum, a material known for its excellent heat transfer properties, which leads to faster heat-up times and more consistent bullet casting. This particular model comes supplied with handles, which are essential for safely manipulating the hot mold.
The inclusion of a sprue plate is fundamental to the mold’s operation, ensuring a clean separation of excess lead after each casting cycle. This specific mold is designed to cast bullets that are ideal for various .375 Winchester applications, offering a balance of weight and aerodynamic shape for good ballistic performance. The hardened cavities ensure a long service life and consistent bullet dimensions over thousands of cycles.
Performance & Functionality
In practice, the Lee Double Cavity Mold .379-250-rf W/handles performs its primary function exceptionally well: casting accurate, consistent bullets. The .379 diameter is critical for ensuring a snug fit in .375 caliber bores, leading to better accuracy and reduced gas leakage. The 250-grain weight is a sweet spot for many .375 loads, providing good momentum and energy for various shooting applications.
The strengths of this mold lie in its efficiency and the quality of the bullets it produces. The double-cavity design effectively doubles the output compared to a single-cavity mold, significantly speeding up the casting process. The Round Nose profile ensures good feeding reliability in most firearms, a vital characteristic for hunting or self-defense scenarios.
However, like any casting mold, achieving optimal performance requires proper technique. The “crimped in place” handles, while functional, can sometimes feel a bit basic compared to more advanced gripping mechanisms. The instruction to not engage the crimp ring when the mold heats up is also important to prevent potential damage or misalignment.
Design & Ergonomics
The design of this Lee mold is focused on function over form, which is typical of the brand’s philosophy. The aluminum construction is lightweight and heats up quickly, which is a major ergonomic advantage for the caster. The double cavity layout is efficient, allowing for two bullets to be cast in quick succession.
The included handles are made of aluminum and are designed to provide a secure grip on the hot mold. While they are functional, they might not offer the same level of comfort as some aftermarket, ergonomically shaped handles, especially during extended casting sessions. The overall feel is one of a tool built for purpose, with no unnecessary embellishments.
The precision of the cavities is evident in the uniformity of the cast bullets, a testament to good design and manufacturing. The inclusion of a molded-in crimp ring is a clever feature that helps maintain handle alignment. This thoughtful detail contributes to the overall usability and ease of operation for the caster.
Durability & Maintenance
This mold is designed for longevity, especially considering its aluminum construction and hardened cavities. Under normal use for its intended purpose, it’s built to last for thousands of bullet castings. The robust design means it can withstand the regular heating and cooling cycles inherent in lead alloy casting without significant degradation.
Maintenance is refreshingly simple; a thorough cleaning with a soft brass brush to remove lead residue is usually sufficient. A light application of a good mold release agent or even graphite powder on the sprue plate and cavity edges can help ensure smooth operation and prevent sticking. There are no complex parts to maintain or replace, making it a low-hassle tool.
A potential point of concern, though minor, could be the sprue plate’s alignment over very extended periods if subjected to excessive force. However, with proper care and avoiding any abuse, this mold should provide reliable service for many years. It’s a tool that rewards careful handling with consistent performance.
Accessories and Customization Options
The Lee Double Cavity Mold .379-250-rf W/handles comes as a complete package, including the essential aluminum handles.
