Dum Dum

Dum Dum is a city and a municipality in the Kolkata Metropolitan Area of North 24 Parganas district in the Indian state of West Bengal. It is a part of the area covered by Kolkata Metropolitan Development Authority (KMDA). Netaji Subhas Chandra Bose International Airport is situated at Dum Dum. During the 19th century the area was home to the Dum Dum Arsenal, a British Royal Artillery facility. It was here that, 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[4][5][6][7][8][9] or more correctly as an expanding bullet. The previous name of Dum Dum was "Domdoma".
