Lee Double Cavity Mold .375 Ball W/handles*

The Lee Double Cavity .375 Ball Bullet Mold with Handles is a practical casting tool for handloaders and blackpowder shooters who want to produce their own round balls. This aluminum mold is built to deliver consistent results without the premium price tag—Lee's design philosophy centers on delivering real value to reloaders who cast their own ammunition. The double-cavity layout means you're producing two bullets per cycle, speeding up your casting workflow compared to single-cavity molds.

Aluminum construction offers genuine advantages in the casting process. The material resists rust and weighs less than steel or iron alternatives, making the mold easier to handle during extended casting sessions. Equally important, aluminum heats and cools faster than heavier metals, which translates to shorter cycle times and more consistent bullet quality. The block halves are CNC-machined to tight tolerances, reducing the risk of metal fatigue over time and ensuring the round balls you cast have smooth, uniform surfaces.

This mold ships with handles included—a detail that matters more than it sounds. Proper handles give you control and safety when working with hot metal, and sourcing quality handles separately adds cost and hassle. Whether you're loading for a .375-caliber blackpowder rifle, a muzzleloader, or a large-bore handgun, this mold is designed to be a workhorse in your reloading setup.

Frequently Asked Questions

What's the advantage of a double-cavity mold over a single-cavity?

A double-cavity mold produces two round balls per casting cycle instead of one, which significantly reduces the time and effort required to produce a large batch of bullets. If you cast regularly, this efficiency gain adds up fast.

Why choose an aluminum mold instead of steel or iron?

Aluminum resists rust without additional maintenance, weighs considerably less (important when you're handling it repeatedly), and heats and cools more quickly. Faster thermal cycling means shorter wait times between shots and more consistent bullet production.

Is this mold suitable for blackpowder rifles and muzzleloaders?

Yes. This .375 double-cavity mold is designed for casting round balls used in blackpowder rifles, muzzleloaders, and large-bore blackpowder handguns.

Are handles included, or do I need to buy them separately?

Handles are included with this mold. They're designed to be strong and durable, so you won't need to source or purchase them separately.
