steel vs aluminium molds
I think it boils down to what you learned on. I learned on lee and they work for me. I have a bullet sticking problem with steel molds. aluminium molds heat up faster and cool faster but I have mastered that. When the bullets come out a little frosty looking I know it getting too hot. I tap the mold on a wet rag. To get the molds up to temp, I put the mold open and upside down on top of the pot as it heats up. generally it's hot enough by the time the lead is ready to pour. As aluminium is a very good conductor of heat, even with a 6 cavity mold it still heats up very well. I took me longer to get in a groove with the 6 cavity mold.
