• Environmental Responsibility: Reusing scrap lead from sources like wheel weights or spent range bullets is an environmentally conscious approach. It reduces waste and prevents lead from entering landfills, promoting a more sustainable shooting hobby.

Getting Started: The Bullet Casting Process with Your Lee Mold

Casting bullets is a rewarding skill that, while requiring attention to detail, is straightforward to learn. Here’s a brief overview of the process with your Lee 90454 mold:

1. Preparation is Key: Ensure your mold is clean and pre-heated. A properly prepared mold will help prevent wrinkles and voids in your cast bullets. You can pre-heat the mold by simply setting it on top of your melting pot, allowing it to absorb heat from the molten lead. Ensure you're working in a well-ventilated area and wearing appropriate safety gear, including eye protection, gloves, and long sleeves.
2. Melting and Pouring: Place your lead alloy (a mix of lead, tin, and antimony for desired hardness) into a dedicated lead melting furnace. Once the lead is molten and at the correct temperature (typically around 700-750°F, depending on your alloy), use the furnace's spigot to pour a stream of molten lead into each cavity of the mold until it overflows slightly onto the sprue plate.
3. Cooling and Sprue Cutting: Allow the lead to cool and solidify in the mold cavities. This usually takes only a few seconds. As the lead solidifies, the sprue (the excess lead on top of the mold) will change color. Once it's solidified, use the sprue plate cutter (part of the integrated design) to smoothly shear off the sprue.
4. Bullet Removal: Gently open the mold handles, and the freshly cast bullets will drop out. Inspect each bullet for completeness and absence of wrinkles or voids.
5. Sizing and Lubrication: Most cast bullets require sizing to their final diameter to ensure a perfect fit in your rifle's bore. This is done using a bullet sizer/lubricator (like a Lee Sizer & Lube Kit), which also applies a thin coat of bullet lubricant to the bullet's grooves. This lubrication is vital for reducing bore leading and improving accuracy.
6. Storage: Store your cast, sized, and lubricated bullets in a cool, dry place until you are ready to load them into cartridges.

Essential Equipment for Bullet Casting (Beyond the Mold)

While the Lee 90454 mold is your core tool for shaping bullets, several other key pieces of equipment are necessary to complete a functional bullet casting setup:

• Lead Melting Furnace: A dedicated electric furnace, such as those offered by Lee Precision, is highly recommended. These provide consistent temperature control and a bottom-pour spout for easy, precise filling of mold cavities.
• Mold Handles: While many Lee double cavity molds are sold with integrated handles, some may require separate purchase of appropriate mold handles to provide a secure grip and leverage for opening and closing the mold. Ensure you have the correct handles for your Lee mold.
• Lead Alloy: Pure lead is too soft for most rifle bullets. You'll need an alloy containing tin and antimony to increase hardness and promote good mold fill-out. Common sources include wheel weights, linotype, or commercially available casting ingots.
• Lubricator/Sizer: After casting, bullets are typically sized to their final diameter and lubricated. Lee offers affordable push-through sizing dies (often used with a reloading press) and dedicated lubricator/sizers that make this process efficient.
• Bullet Lube: Essential for reducing friction, preventing leading in the bore, and ensuring smooth bullet travel. Various types are available, from stick lubes to liquid alox, each with its own advantages.
• Safety Gear: Non-negotiable. Always wear heat-resistant gloves, long-sleeved clothing, closed-toe shoes, and most importantly, industrial-grade eye protection and a respirator or ensure excellent ventilation to protect against lead fumes.

Casting for the Legendary .270 Winchester Cartridge

The .270 Winchester, introduced by Winchester in 1925, has stood the test of time as a premier hunting cartridge. Its reputation for flat trajectory, moderate recoil, and effective terminal performance on medium to large game is well-deserved. When casting bullets for the .270 Winchester, you can further enhance its capabilities:

• Ballistic Considerations: Cast bullets often perform optimally at slightly lower velocities than jacketed bullets to prevent leading the bore. However, with the right alloy, lubricant, and load development, cast bullets can deliver excellent accuracy and impressive performance within practical hunting ranges.
• Optimizing for Performance: Experiment with different bullet weights (which can vary slightly based on your chosen alloy and the mold's design), powder charges, and seating depths to find the "sweet spot" for your rifle. The Lee 90454 mold provides a consistent foundation for this precise load development.
• Applications: While often thought of as a hunting cartridge, the .270 Winchester with cast bullets can also be a superb choice for target shooting, informal plinking, or even varmint control where lighter, custom loads might be desired. The cost-effectiveness of cast bullets makes high-volume practice economical, allowing shooters to hone their skills without concern for ammunition expenses.

Maintaining Your Lee Mold for Generations of Use

Your Lee 90454 mold is built to last, but proper care and maintenance will ensure it continues to produce high-quality bullets for decades:

• Cleaning and Care: After each casting session, allow the mold to cool completely. Clean any lead residue or carbon buildup from the mold cavities and sprue plate using a soft brass brush or a wooden toothpick. Avoid using harsh chemicals or abrasive materials that could damage the aluminum. A light coating of mold release agent or anti-rust oil can be applied for long-term storage.
• Storage Tips: Store your mold in a dry, temperate environment to prevent rust on the steel components (like the sprue plate). A dedicated storage box or drawer helps protect it from dust and accidental damage.
