Definition of dumdum in English:


(also dumdum bullet)

    • ‘They used bullets that are called dumdum bullets, and when they hit, whatever they hit, there are fragments everywhere, and they shot at the cameramen.’
    • ‘Bullets cause injury by transferring their energy into the body tissues; the design of the bullet influences this process, with hollow nosed or dumdum bullets being designed to maximise energy transfer.’
