Dum Dum is a city and a municipality of North 24 Parganas district in the Indian state of West Bengal. It is close to Kolkata and also a part of the area covered by Kolkata Metropolitan Development Authority (KMDA). <br /><br />During the 19th century the area was home to the Dum Dum Arsenal, a British Royal Artillery armoury, where, in the early 1890s, Captain Neville Bertie-Clay developed a bullet with the jacket cut away at the tip to reveal its soft lead core (see hollow-point bullet), known informally as a dum-dum, or more correctly as an expanding bullet. The previous name of Dumdum was "Domdoma". <br /><br />Source : <a title="Dum Dum on Wikipedia" href="https://en.wikipedia.org/wiki/Dum_Dum" target="_blank">Wikipedia</a>
