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.
Longest Sniper Shot Record Broken! British Super Sniper Craig Harrison has uprooted the Canadians for the longest sniper shot on record, 1.54 miles! Not only did he beat the record by 150 ft., but took two shots that each killed a Taliban machine gunner. At 8,120 ft., which is 3,200 ft. further than the range of his Accuracy International L115A3, conditions had to be perfect. The .338 Lapua round again proves itâs worth in the battlefield.
