Overview
This two-cavity mold is built for reloaders who want a practical option for casting .30 caliber bullets with a flat nose profile and gas check design. Its aluminum construction is intended to keep the blocks rust resistant and easier to handle during longer casting sessions, while the CNC-machined block halves are described as providing roundness and size control. Lee notes that aluminum molds heat up and cool down quickly, so a few casts may be needed before producing good bullets. It is a straightforward choice for shooters setting up their own cast-bullet supply, with handle included.

Considerations & Trade-offs
- Aluminum mold blocks heat up and cool down faster than iron or steel, so the first few casts may not produce usable bullets until the mold reaches a steady temperature.
- Lee notes that the listed bullet weight is based on a suggested alloy; actual weight can vary with the alloy mixture used.
- The mold is designed for 30 caliber, 0.309-inch bullets with a flat nose and gas check, so it is purpose-built rather than a general-purpose mold.
- Lee advises against spray-type mold release products, which adds an extra handling consideration during setup and use.
