Don't you think that the newtron-tomographic and radiograpic images of the cannonballs from Mary Rose may also suggest that the lead ball could have been casted arund the iron core? The position of the iron core on the edge of one side of the lead ball indicates to me that it was casted and the iron clod was positioned outside of the centre while laying on the bottom of form. Even when i guess that an experienced metal caster should be able to produce balls with a centered core.

Or is it possible that the emphasis was intentially dislocated from the center of weight? - Bus this wouldn't make any sense to me.
