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.
These are all impressive but Iâm sure the actual record is higher, my uncle was a scout sniper in the USMC and his longest shot was 2783 yards,and apparently Guinness didnât want to go to Afghanistan to confirm it so it was never officially the longest shot. So realistically, Iâm sure that happens more often than not.
