[QUOTE="Bullet bumper, post: 700992, member: 17844"] Unfortunately melting the core dose not work like that. What happens is the molten metal will expand and then on cooling shrink back more at the centre far more than the sides . Leaving an uneven depression at the surfaces centre . This depression has to be levelled out in the core seating process to restore good concentric form and hence good rotational balance . You can't do that with the ogive already formed . You just end up with a depression in the core surface that is unreliably shaped. Some might be ok and some will not be as accurate as before . Without a flux inside the jacket it will not bond to any useful degree. If the bullet is already chemical bonded then the heat may destroy that bond . [/QUOTE]
