I am leaning towards towards the 40# Magma Master pot for the additional $200.
I really want a 40# Magma pot. I have been using an RCBS for 25 years and it is a good pot. The ability to have 40 pounds of melt means I can cast about all I can stand and never need to add more to the pot.
Anyone ever use the 90# Magma? That would be a workout to drain.
