I try to restrict myself to the 60 calibers that Forster sells dies for, but Calhoon seems to be making parts or somehow getting the parts for other calibers.

Someone must be making dies for customers and know all about this.

Calhoon could very well be getting them from Foster, most likely as a "special and propritary" run of the parts.
