Let’s Dive into Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374
Casting your own bullets is a rewarding process, putting you in control of your ammunition from start to finish. The Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374, crafted by Lee Precision, promises to deliver accurate and consistent .457 diameter projectiles suitable for a variety of rifle applications. For the handloader looking to optimize their rifle’s performance, these molds offer a cost-effective and highly customizable solution.
I’d been searching for a reliable method to produce consistent .457 diameter bullets for my .45-70 Sharps rifle. Factory ammunition can be expensive and sometimes lacks the specific characteristics I desire for different shooting scenarios. I was looking for something that allows me precise control over bullet weight and alloy composition.
Upon receiving the Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374, I was immediately struck by its lightweight design. The aluminum felt solid, although a bit less substantial than some of my older iron molds. Compared to steel molds, these heat up and cool down much faster. This was preferable to some more expensive brass moulds because I could cast bullets much faster.
I considered molds from Lyman and RCBS. However, Lee’s reputation for affordability and the specific design of this mold, optimized for the .45-70, swayed my decision. The double cavity design also promised faster casting times than single cavity options.
My first impression was one of cautious optimism. The mold looked well-machined, and the aluminum seemed durable enough for the task, although I anticipated a learning curve to master the nuances of casting with aluminum. The light weight was appreciated, especially compared to heavier steel molds I’ve used in the past.
Real-World Testing: Putting Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374 to the Test
First Use Experience
My initial testing took place in my reloading workshop. I set up my casting furnace and prepared a lead alloy suitable for my .45-70. The Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374 heated up quickly, and within minutes, I was ready to cast.
I tested the mold with both a traditional lead/tin alloy and a harder alloy containing antimony. The mold performed well with both, though the harder alloy required slightly higher temperatures for optimal fill-out. There were no issues when using the mold in my moderately humid shop environment.
The mold required a bit of a learning curve, especially regarding temperature control. However, after a few casting sessions, I felt confident in my ability to produce high-quality bullets. The initial bullets were slightly wrinkled, but after adjusting my casting technique and temperature, the fill-out improved dramatically.
Extended Use & Reliability
After several weeks of regular use, the Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374 has proven to be a reliable tool. The mold still closes tightly and casts consistent bullets. Minimal cleaning is needed.
I’ve cast hundreds of bullets using this mold, and it shows minimal signs of wear and tear. I apply a light coat of mold release to the sprue plate before each casting session to prevent sticking and maintain smooth operation. The aluminum has held up very well to repeated heating and cooling cycles.
Maintenance is straightforward. A quick wipe-down with a clean cloth after each use is usually sufficient. Occasionally, I’ll use a lead-removing cloth to clean the mold faces and sprue plate.
Compared to some of my older iron molds, the Lee mold requires a bit more finesse to get the temperature just right. But with practice, it produces bullets of comparable quality, and the faster heating and cooling times are a significant advantage. The mold’s performance has exceeded my initial expectations, especially given its relatively low price.
Breaking Down the Features of Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374
Specifications
The Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374 is designed to cast .457 diameter bullets, a popular size for .45-70 rifles and other similar calibers. It is constructed from aluminum for rapid heating and cooling. It casts two bullets simultaneously, increasing casting speed.
The mold is designed to cast a 405-grain flat-nosed bullet (hence the “405F” designation). The bullet’s design is ideal for hunting and target shooting, offering good accuracy and stopping power. This specific bullet design is very well suited for black powder cartridges. The aluminum construction allows for rapid temperature cycling, vital for efficient casting.
Performance & Functionality
The Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374 performs admirably, provided the user takes the time to learn its nuances. Once the mold temperature and casting technique are dialed in, it consistently produces accurate and uniform bullets. The mold fills out well, and the bullets drop cleanly, minimizing rejects.
The mold’s strength lies in its ability to quickly produce a large number of bullets. The weakness is the aluminum construction, that requires a more careful handling and temperature management than some steel moulds. It meets my expectations for accurate .45-70 projectiles.
Design & Ergonomics
The aluminum construction of the Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374 makes it lightweight and easy to handle. The mold is designed for use with Lee’s standard mold handles (sold separately). It’s comfortable to use for extended casting sessions.
The mold is relatively user-friendly, but some experience with casting is helpful. The aluminum requires careful temperature control, and beginners may experience some initial difficulty achieving consistent results. It requires a consistent approach in order to produce the best bullets.
Durability & Maintenance
While aluminum is not as durable as steel, the Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374 should last for many years with proper care. Avoid dropping the mold or using excessive force when closing or opening it. Regular cleaning and lubrication will also extend its lifespan.
Maintenance is simple, requiring only occasional cleaning and lubrication. Keep the mold faces clean and free of lead buildup. The sprue plate should be lightly lubricated to ensure smooth operation.
Accessories and Customization Options
The Lee Aluminum Double Cavity Rifle Molds Number 457-405F 90374 itself is relatively simple and offers limited customization options. However, the bullets it produces can be customized through alloy selection and sizing. The mould requires Lee handles, which are sold separately.
The mold is compatible with standard bullet sizing dies, allowing you to fine-tune the bullet diameter to match your rifle’s bore. You can also experiment with different powder coatings or lubes to further enhance performance. The mould does not come with any accessories.
