Is it possible to create and use a double cavity 50 cal mold for the magma master caster? I notice that magma only sells single cavity molds in the 50 cal size. I suspect this is because the pour holes in the sprue plate would not be directly under the stream of lead. Also would the material between the two cavities be too thin to align the cavities with the pour stream?
I am looking to do a enlarged H&G68 in .501 for the 50GI.
