Lee Precision 90436 Mold Double Cavity Round Ball .440 Capacity 2 Bullets

The Lee Precision 90436 is a double cavity round ball mold designed for shooters and reloaders casting their own .440 diameter projectiles. Whether you're loading for a blackpowder rifle, revolver, or muzzleloader, this two-cavity mold lets you produce pairs of consistent cast balls in each pour—speeding up your production compared to single-cavity tools. The mold comes complete with handles, so you're ready to start casting out of the box.

Built from aluminum, this mold offers real advantages over traditional steel or iron alternatives. The lighter weight makes it easier to handle during long casting sessions, and aluminum's superior heat conductivity means faster warm-up and cool-down cycles between pours. That translates to shorter wait times and higher productivity at the casting bench. The block halves are CNC-machined to tight tolerances, which keeps the cavity walls smooth and reduces stress points that can develop into cracks over time—a detail that extends mold life.

Lee Precision has engineered this mold for the working reloader who values reliability and value. The double-cavity design and included handles make it a practical choice for anyone serious about casting their own lead balls rather than paying per-round retail prices. Pair it with a Lee casting furnace and ladle, and you've got a complete, affordable entry into the craft.

Frequently Asked Questions

What calibers and firearms can I use these cast balls in?

The .440 diameter balls are suitable for blackpowder rifles, revolver loads, and muzzleloaders chambered for that projectile size. Check your firearm's manual or load data to confirm compatibility with .440 round balls before casting.

Do I need to buy handles separately, or are they included?

Handles are included with the Lee Precision 90436. You'll have everything needed to start casting immediately.

Why choose aluminum over steel or iron molds?

Aluminum is lighter to hold during extended casting sessions, conducts heat more efficiently so it reaches temperature faster and cools quicker between pours, and resists rust. The tradeoff is that aluminum is slightly softer, but Lee's CNC machining and design minimize wear and fatigue.

How many balls does this mold produce per casting cycle?

The double cavity design produces two balls in each pour, doubling output compared to single-cavity molds.
