...even though the first time you pick one up and feel the weight, you'll wonder what you have gotten yourself into.
You got that right Frank!
It must weigh 2#, then suspend that on the end of the lee 6 cavity handles. It gets heavier as the session gets longer.
But that extra weight means it holds heat much better than aluminum. The other side of the coin is that it takes longer to reach casting temp. Another + is it won't rust! The sprue plate and guide bushings and pins are steel, they need to be kept dry.
Edited to change the 2 to a 6 on the handles.
