They either think I'm an idiot or the guy I talked to IS one. I suspect both. All I wanted to know is what taper their bullet sizing dies are cut to. Easy question and hardly a trade secret. He informed me that they make the dies by "pushing a carbide ball through them." So I asked how they achieved a taper by pushing a rigid sphere through a die body blank. His reply was "I don't know but that is information we don't give out." Apparently the wizard that they hired to violate the laws of physics holds his spell book very close to his chest. Sheesh!! Guess I'll have to just do the math myself. And start buying someone else's dies.
