I have a old NEI 4 cavity mold I bought in the 80s. It is the best casting mold I have ever used. The mold is marked 228 but has very long nose and casts 255. This long round nose feeds great but I have no use for. I am thinking of trading it off but was wondering if pins could be made that would make it a round nose flatpoint about 225 grains. Any thoughts on this would be welcome.
