Availability: In Stock
The Lee 6-Cavity Bullet Mold C312-155-2R is a dedicated casting tool for 7.62x39mm reloaders who want to produce consistent, high-volume bullets at the bench. This aluminum mold throws six .312-diameter, 155-grain bullets per pour—a serious productivity gain over single-cavity alternatives. The 2-ogive radius design and gas-check feature make these rounds suitable for reliable ignition and chambering in modern 7.62x39mm rifles. Whether you're building ammunition for your Mosin-Nagant, AK-pattern rifle, or any other x39 platform, this mold lets you cast bullets in batches instead of one at a time, which matters when you're working toward volume.
Built from machined aluminum with a hard-anodized sprue plate, the mold resists rust and corrosion through years of use. Lee Precision engineered these blocks to tight tolerances so each cavity produces uniform bullets, shot after shot. The aluminum construction also means faster heat cycling—your mold reaches casting temperature quickly and cools enough between pours to keep you moving without long waits.
One critical detail: Lee Precision specifically advises against spray-type mold release products on this mold. Residue buildup inside the cavities can gradually reduce bullet diameter, throwing off your carefully loaded rounds. Instead, the manufacturer recommends the traditional method—smoking the mold with a wooden match, beeswax candle, or butane lighter before each casting session. It takes seconds, costs nothing, and keeps your bullets in spec. Follow that simple discipline and you'll get reliable, consistent casts for thousands of rounds.

Lee Precision does not recommend spray-type mold release products. Spray residue can accumulate inside the cavities and gradually shrink bullet diameter, ruining your loads. Instead, smoke the mold lightly with a wooden match, beeswax candle, or butane lighter before each casting session. It's the time-tested method and keeps your bullets in spec.
Yes. The C312-155-2R is designed specifically for 7.62x39mm ammunition. The .312-inch diameter and 155-grain weight are standard for this cartridge, and the gas-check feature supports reliable feeding and ignition in AK-pattern rifles, Mosin-Nagants, and other x39 platforms.
Six. The six-cavity design lets you cast six bullets simultaneously, which significantly speeds up your casting workflow compared to single-cavity molds.
The mold blocks are machined aluminum with a hard-anodized sprue plate. Aluminum heats and cools quickly, which keeps your casting pace steady, and the anodized sprue plate resists rust and corrosion through years of regular use.
