Lee classic cast, your best choice, no debate. We hashed this out over on THR, as to just what material the Lee classic cast, and classic turret were made of. Was it cast steel, or cast iron?
It's a long read, BUT if you really want to know what others are having for experience, then spend a little time over there.
Oh, for those that don't have the time, the Lee classic line is made of cast iron. They modify the steel railroad rails by adding carbon to make it cast iron.
The Lee classic cast is able to take the LNL bushings, by removal of the 7/8x14 bushing, then inserting the LNL adapter in the 1-¼ threads.
