New meaning to the term "hammer forge?" How do you control the diametral symmetry (i.e., the mold parting line has to be exactly on the diameter centerline, else you have more material on one side of the mold than the other, effectively locking it shut once the lead hardens). Well, maybe not locking it shut, but making it extremely difficult to pry the bullet out of the mold.
Pretty slick idea, Ed.
