A term that is sometimes used for oceanic crust rocks is sima, which is short for magnesium silicate, a common component of these rocks. Another term for these undersea igneous rocks is mafic, which comes from the fact that they are high in magnesium and iron. Basalt and gabbro are examples of mafic rocks.
The current record is held by Briton Corporal of Horse (CoH) Craig Harrison, of the UKâs Household Cavalry, who recorded a 2,475 m (2,707 yd) shot (confirmed by GPS) in November 2009, also during the War in Afghanistan, in which he hit two Taliban insurgents consecutively.
The new world record for longest shot is 3,400 meters (3,720 yards). Sport shooter and small-arms designer Vladislav Lobaev set a new world record for long-range shooting. He set the record with a Lobaev Arms SVLK-14 S rifle of his own design.
