Welcome to War and Tactics!    War and Tactics Forum is currently undergoing some modifications that might disable features you are used to. This is unabvoidable as we have to update the forum engine to a new structure that is incompatible with many of the features we had used so far. The good news: WaT will be more secure and stable, and most of the features we uninstalled will be a natural part of the new structure anyway. For the rest we will be looking for solutions.

Craig Harrison is a Corporal of Horse (CoH) of the Household Cavalry of the British armed forces, and holds the record for the longest confirmed sniper kill in combat, at a range of 2,475 m (2,707 yd). Established in November 2009, this exceeds the previous record of Rob Furlong set in 2002 by 45 m (49 yd)
In November 2009 CoH Craig Harrison struck two Taliban machine gunners south of Musa Qala in Helmand Province in Afghanistan with two consecutive shots at a range of 2,475 m (2,707 yd) using a L115A3 Long Range Rifle. The Schmidt & Bender 5-25x56 PM II LP telescopic sight used on the L115A3 Long Range Rifle adjusts in 0.1 milliradian or mil  increments and has an maximal vertical elevation range of 26 milliradian. At a distance of 2,475 m (2,707 yd) 1 adjustment increment of 0.1 milliradian equates to a 24.75 cm (9.7 in) point of impact shift.

This feat is not typical for the effective range with a high first-hit probability of the employed rifle system on static targets (see maximum effective range). The shots were aided by the ambient air density near the valley in which Musa Qala is situated and where CoH Harrison operated, which is significantly lower than at sea level due to Musa Qala's 1,043 m (3,422 ft) mean elevation.
In the reports CoH Craig Harrison mentions the environmental conditions were perfect for long range shooting, no wind, mild weather, clear visibility. Mr. Tom Irwin, a director of Accuracy International, the British manufacturer of the L115A3 rifle, said: “It is still fairly accurate beyond 1,500 m (1,640 yd), but at that distance luck plays as much of a part as anything.”
According to JBM Ballistics, using drag coefficients (Cd) provided by Lapua, the L115A3 has an approximate supersonic range (speed of sound = 340.3 m/s) of 1,375 m (1,504 yd) under International Standard Atmosphere conditions at sea level (air density ? = 1.225 kg/m3) and 1,548 m (1,693 yd) at the 1,043 m (3,422 ft) altitude or elevation (air density ? = 1.1069 kg/m3) of Musa Qala. This illustrates how environmental condition differences can significantly affect bullet flight.



The external ballistics software program JBM Ballistics further predicts that the bullets of British high pressure .338 Lapua Magnum cartridges using 16.2 g (250 gr) Lapua LockBase B408 bullets fired at 936 m/s (3,071 ft/s) muzzle velocity under International Standard Atmosphere conditions at 1,043 m (3,422 ft) elevation (air density ? = 1.069 kg/m3) and assuming a 100 m (109 yd) zero arrive at 2,475 m (2,707 yd) after approximately 6.017 s flight time at 251.8 m/s (826 ft/s) velocity and have dropped 120.95 m (4.762 in) or in angular units 48.9 milliradian (168 MOA) on their way. To accomplish such an extreme range shot the Schmidt & Bende] 5-25x56 PM II LP telescopic sight has to be mounted with a vertically canted base or canted rings to be able to dial in the required amount of vertical adjustment.

Designed to achieve first-round hit at 600m and harassing fire out to 1100m, the Accuracy International L96 sniper rifle has been upgraded with a new 3-12 x 50 sight and spotting scope.

Lol yes, the target would be dead long before he could hear or see the shot, probably the second guy got hit within seconds too.
