Lee mold blocks are machined from aluminum blocks making them rust resistant. Aluminum molds heat up and cool down faster than iron or steel molds so good bullets can usually be produced after only a few casts. In addition, they are one-third the weight of iron or steel mold blocks for less fatigue during extended casting sessions. To ensure the best possible bullets, mold block halves are CNC machined for unmatched roundness and size control.

A note from Lee Precision on their bullet molds:
Lee Precision does not recommend the use of any spray type mold release products in their bullet molds. The use of such products may result in a build-up of the release product in the bullet mold cavity, reducing the diameter of the bullets cast from the treated mold. Instead, Lee Precision recommends smoking the mold with a wooden match, beeswax candle or a butane lighter as described in their provided bullet mold instructions.
