Outstanding; i just went to a shop downtown and when i was back the riddle was already cracked; within precisely 22 minutes.
Indeed a sling projectile, called by archeologists 'gland'; full name glans plumbeae.
As apparently there are no mould seams, it must be the later beaten plate version, of so called biconic shape, which could be dated around the last phase of Roman civil wars (2-1 centuries BC).
Found somewhere in the middle of the country; there are not many around.
