Last week I made 2 phone calls. To whom you ask.

Call number 1 was to Lee Precision.

Asked them to consider making carbide die sets for the 500 JRH and 500 Linebaugh since Magnum Research is making production revolvers in these calibers.

Call number 2 was to the folks at Magnum Research asking them to contact Lee Precision about making carbide dies.

Both companies seemed genuinely interested in the idea.

I guess only time will tell.
