Cuttin' Edge, a Dalek Bounty Hunter of the Wayfarer during the Second Dalek War, used bastic-headed ammunition to infect a Dalek with a virus that gradually ate away at its (Time War) casing. However, the Dalek was able to trasmit defence protocols to other Daleks, so the bullets no longer caused them damage afterwards. (PROSE: Prisoner of the Daleks)
