Make my pistol / lever gun molds all aluminum especially when casting with harder lead alloys. I like the lighter weight of the molds. Bottom pour or ladle casting doesn't matter. Keep the sprue plate lubed to prevent galling and the molds should last forever. For the larger long range black powder cartridges with 30-1 / 20-1 alloy I still prefer iron/meehanite molds because of the higher melt temp required to cast match grade bullets. Tried brass molds and never really cared for it at the time.
