Does anyone know what the comparable machine screw would be that fits the RCBS dies for 357/38?
I am thinking of making a few custom ones on the lathe. Then use JBWeld to make an epoxy filled base to fit 180gr WFN, Sierra 158gr JSP, and Magtech SJHP rounds.
Thoughts? Could I get away with making it from aluminum instead of steel? Or maybe have the main part steel and just a replaceable end with 6065 or 7071 that the bullet seater would screw into?
