Craig Harrison (British Army soldier)

Craig Harrison (born November 1974)[1] is a former Corporal of Horse (CoH) in the Blues and Royals, a cavalry regiment of the British Army, who from 2009 to 2017 held the record for the longest confirmed sniper kill in combat, at a range of 2,475 m (2,707 yd).[1][7] In the reports, Harrison mentions the environmental conditions were perfect for long range shooting: no wind, mild weather and clear visibility.Even with a 13.1 mil canted mount the employed sighting system is not able to dial in over 39.1 milliradian of vertical aiming correction, which is significantly less than Harrison required during his record shot.[9][10] The external ballistics software program by JBM Ballistics predicts that the bullets of British high pressure[d] .338 Lapua Magnum cartridges using 16.2 g (250 gr) Lapua LockBase B408 bullets fired at 936 m/s (3,070 ft/s) muzzle velocity under International Standard Atmosphere conditions at 1,043 m (3,422 ft) elevation[e] assuming shooting and target positions are at equal elevation and a 100 m (110 yd) zero (the distance at which the rifle is sighted in) arrive at 2,475 m (2,707 yd) distance after approximately 6.017 seconds flight time at 251.8 m/s (826 ft/s) velocity and have dropped 120.95 m (396.8 ft) (in angular units 48.9 milliradian, 168 MOA) on their way.The long horizontal line at 5× zoom or magnification represent 49.1 milliradian (168.6 MOA) or slightly over the required assumed vertical elevation.
