I would be very wary about buying used molds off E-Bay. A lot of people screw up molds and do not even know it.

If you are looking for some good deals on used equipment, then I would recommend looking on the "Cast Boolit Forum". There are a great bunch of guys over there. They are full of knowledge. They are willing to help with any problems. And you can find a lot of good used equipment over there. I just bought a used RCBS mold for my 44 magnum from a guy over there. I got a great deal, on an almost unused mold. Tom.
