Bastic bullets prove useless against the Daleks, who disintegrate them with their shields. (TV: The Parting of the Ways)

Bastic bullets were projectiles fitted with bastic heads, capable of penetrating Dalek casings. Orcini destroyed a Dalek on Necros by firing bastic bullets at it. (TV: Revelation of the Daleks) As claimed by Jack Harkness, bastic bullets could blow a Dalek wide open. (TV: The Parting of the Ways)

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 casing. However, the Dalek was able to transmit defence protocols to other Daleks, so the bullets no longer caused them damage. (PROSE: Prisoner of the Daleks)

Eventually, Dalek force field technology advanced to the point where bastic bullets were no longer effective against them. This was the case in the Battle of the Game Station in 200,100, although at least one Dalek was blinded after being shot in the eyestalk. (TV: The Parting of the Ways)
