Lee Precision 90406 Double Cavity Ball Mold .311 45.16gr Round Ball

The Lee Precision 90406 double cavity ball mold casts a .311 diameter round ball weighing 45.16 grains, purpose-built for muzzleloading and black powder shooting. The two-cavity block produces two balls per pour, letting reloaders build up a stockpile of projectiles quickly without babysitting a single-cavity mold.

The mold is built around machined aluminum blocks paired with a hard anodized sprue plate for clean sprue release and long service life. Comfortable wood handles are included along with the sprue plate, and the tangential cut-off design minimizes sprue waste and reduces flash on finished balls. Aluminum blocks will not rust the way cast iron molds can, making storage and ongoing maintenance simple.

Sized for muzzleloader calibers that accept a .311-inch round ball, this Lee mold is a popular choice for hunting, plinking, and historical shooting with black powder or black powder substitutes. Like other Lee casting tools, the 90406 is straightforward to set up and use right out of the box.
