Diameter of the punch where it enters the die is probably ok, if not you can spin it down in a few seconds by putting the top punch in an electric drill and sanding the part that enters the die. As for the nose, if it doesn't fit you can use a bit of epoxy putty to fill the gaps by setting up the press, die, and top punch, then lightly pressing the epoxy-loaded top punch on a 45 RNFP bullet held in the sizing die.
