So I only have Lee Molds and am very happy with them, I want to add a Keith design to my .44 molds and have to look else where. I have decided on either Arsenal (most likely) or Accurate in a brass mold. With my Lee molds a wet sponge is my friend, they are all 2 cavity and heat up quick especially with heavier grain bullets. For those of you using brass, I know they maintain heat better so does that transfer to more consistent casts for you during a session without having to cool the mold? Thank you, Darrin.
