This level of control enables you to fine-tune your loads for optimal accuracy and performance in your specific firearms, whether for target shooting, hunting, or general plinking.
• Self-Sufficiency: In uncertain times, having the ability to produce your own critical components like bullets provides immense peace of mind. You become less reliant on external supply chains and market fluctuations.
• Recycling and Environmental Responsibility: Casting offers an excellent way to recycle spent lead from ranges or other sources, contributing to environmental conservation and further reducing your material costs.

For anyone committed to optimizing their reloading process and maximizing their shooting budget, the Lee 90303 mold is an investment that quickly pays for itself.

Introducing the Lee 90303: A Closer Look at its Superior Design

The Lee 90303 Double Cavity Bullet Mold is a testament to Lee Precision's commitment to delivering high-quality, user-friendly, and efficient reloading tools. This specific model is expertly designed to cater to the needs of .38 caliber firearms, including popular cartridges like the .38 Special and .357 Magnum.

Let's dissect the features that make this mold a standout choice:

Double Cavity Efficiency

• Accelerated Production: The "double cavity" design is a game-changer for production speed. Instead of casting one bullet at a time, this mold allows you to cast two bullets with each pour of molten lead. This dramatically reduces the time and effort required to accumulate a substantial quantity of bullets, making your casting sessions far more productive. If you've ever thought, "How can I cast bullets faster?", a double cavity mold like the Lee 90303 is the direct answer.
• Consistent Output: Producing two bullets simultaneously from a single pour helps ensure that both bullets cool at a similar rate, contributing to greater consistency in weight and dimensions.

Precision Aluminum Construction

• Exceptional Molding Properties: Lee Precision molds are renowned for their use of aluminum. Aluminum offers several critical advantages over traditional iron or steel molds. It heats up quickly and maintains a consistent temperature, which is crucial for producing perfectly filled-out bullets. This rapid heat transfer ensures excellent "fill-out" of the mold cavities, preventing imperfections like wrinkled bullets or voids.
• Lightweight and User-Friendly: Aluminum is significantly lighter than other mold materials, reducing user fatigue during extended casting sessions. This makes the casting process more enjoyable and manageable, especially for beginners or those planning to cast hundreds or thousands of bullets.
• Durability and Longevity: Despite its lightweight nature, aluminum, when properly cared for, provides excellent durability. These molds are built to withstand countless casting cycles, offering years of reliable service.
• Minimal Sizing Required: One of the most significant benefits of Lee aluminum molds is their ability to cast bullets that are often ready to use "as cast" without the need for additional sizing. This saves you an entire step in the reloading process, streamlining your workflow and reducing the need for extra equipment like a bullet sizer. This feature is particularly appealing if you're asking, "Can I cast bullets that don't require sizing?"

Optimized for .38 Caliber: .358 Diameter, 158 Grain Round Flat Nose (RF)

• Versatile Caliber: The .38 caliber (.358 diameter) is one of the most popular and versatile pistol calibers globally, used in countless revolvers and some carbines. This mold is perfectly suited for handloaders focusing on common handgun cartridges like the .38 Special, .357 Magnum, and other compatible firearms.
• Ideal Bullet Weight: A 158 grain bullet is a classic and highly effective weight for .38 caliber applications. It strikes an excellent balance between recoil, energy transfer, and stability, making it suitable for a wide range of uses from target shooting to personal defense.
• Round Flat Nose (RF) Profile: The Round Flat Nose (RF) bullet profile is specifically designed for reliable feeding in a wide array of firearms, particularly revolvers. Its broad meplat (flat tip) offers several advantages:
  • Consistent Accuracy: The flat nose provides a stable bearing surface, often contributing to excellent accuracy in many revolvers and lever-action rifles.
  • Clean Punching of Paper Targets: The flat meplat creates a clean, easily discernible hole in paper targets, simplifying scorekeeping.
  • Effective for Plinking and Hunting: While primarily known for target use, the flat nose also performs well for small game hunting where energy transfer is desired without over-penetration.

Integrated Handles and Sprue Plate

• Complete Package: Unlike many molds that require separate purchase of handles, the Lee 90303 comes complete with integrated handles. This means you have everything you need to start casting right out of the box (aside from the lead and melting pot). The handles provide a comfortable and secure grip, ensuring safe and efficient operation.
• Precision Sprue Plate: The included sprue plate is a critical component that cuts the excess lead from the base of the newly cast bullet. Lee's sprue plates are designed for smooth, precise operation, ensuring a clean cut and a uniform bullet base, which is vital for consistent accuracy.

The Casting Process: Where Your Lee Mold Shines

Integrating the Lee 90303 mold into your bullet casting setup is straightforward. For those wondering, "How do I cast my own bullets?", here's a simplified overview where this mold plays a central role:

1. Preparation: Gather your lead alloy (ensure it's clean and suitable for casting), a lead melting pot, a heat source, safety gear (gloves, eye protection, long sleeves), and a container for your finished bullets.
2. Melt the Lead: Place your lead alloy into the melting pot and heat it until it reaches the proper casting temperature. The exact temperature will depend on your alloy, but typically ranges from 700-800°F (370-425°C).
3. Preheat the Mold: It's crucial to preheat your Lee mold. This can be done by dipping it in the molten lead for a few minutes or placing it on top of the melting pot to absorb heat. A properly preheated mold is essential for achieving complete fill-out and consistent bullets.
4. Cast the Bullets: Once the mold is hot, position it under the spigot of your melting pot. Open the spigot to pour lead into both cavities until they are completely filled and a puddle forms on top of the sprue plate.
5. Cut the Sprue: After the lead in the sprue plate has solidified (this happens quickly), use the sprue plate cutter to shear off the excess lead. The clean cut ensures a flat, uniform base for your bullets.
6. Eject the Bullets: Open the mold handles to release the two freshly cast bullets. Place them on a soft cloth or in a water bath to cool (depending on your desired hardness and cooling method).
7. Repeat: Close the mold, and you're ready for the next pour. The double cavity design significantly speeds up this repetitive process.

This seamless integration ensures that your focus remains on quality production, making the Lee 90303 an ideal choice for both novice and experienced casters alike.

Beyond the Mold: Maximizing Your Investment

Owning a quality mold like the Lee 90303 is just one piece of the puzzle. To truly maximize your bullet casting investment, consider these aspects:

• Lead Alloy Selection: Different lead alloys have varying hardnesses (measured in Brinell Hardness Number, BHN). For .38 caliber pistol bullets, a softer alloy (around 10-12 BHN) is generally sufficient for standard velocities, while harder alloys might be preferred for magnum loads or to prevent leading in barrels. Researching the right alloy for your specific needs will optimize performance.
• Bullet Lube: Cast bullets typically require lubrication to prevent leading in the barrel and reduce friction. Options include traditional stick lubes, liquid lubes, or powder coating. Lee molds are often compatible with various lubrication methods.
• Safety First: Always prioritize safety when casting lead. Work in a well-ventilated area, wear appropriate personal protective equipment (PPE) including eye protection, heat-resistant gloves, and long sleeves/pants. Ensure children and pets are away from the casting area.
• Mold Care: Proper care extends the life of your mold. After use, clean it thoroughly to remove any lead residue. Store it in a dry place to prevent rust on steel components (like the sprue plate hinge) and protect the aluminum from scratches. A light coating of oil on steel parts is beneficial.
