Title: Canadian sniper's bullet flew for ten seconds at speed of 792mph: Soldier even had to account for the Earth's curvature as he killed jihadi from two miles away with shot so powerful it can hit a target through walls

A sniper has earned a place in military history by killing an Islamic State jihadi from more than two miles away. The elite Canadian soldier took out the fanatic from a high-rise building during an operation in Iraq last month, it emerged yesterday. He was so far away that the bullet took almost ten seconds to reach its target. A military source said the shot was taken during an IS attack on Iraqi forces. The soldier was 2.1 miles, or 11,614ft, away from the jihadi, beating the previous British-held record of 1.5 miles. The bullet from the rifle travelled at an eye-watering 792mph - faster than a Boeing 737 - and took ten seconds to reach its target The sniper, who cannot be named for security reasons, is part of Canada's Special Forces, assisting Iraqi forces in the war against IS. 'The shot in question actually disrupted a Daesh attack on Iraqi security forces,' a military source told Toronto's Globe and Mail newspaper. The source added: 'Instead of dropping a bomb that could potentially kill civilians in the area, it is a very precise application of force – and because it was so far away, the bad guys didn't have a clue what was happening.' The source described the difficulty of the shot, explaining that the sniper had to account for wind, ballistics and even the Earth's curvature. A military insider said: 'This is an incredible feat. It is a world record that might never be equalled.' The soldier used a McMillan TAC-50 sniper rifle – so powerful it can shoot through walls. It is designed to be effective only up to 1.2 miles. The Canadian sniper worked with a spotter, whose job is to help get an accurate shot. Spotters use binoculars and can see the target more clearly than the sniper, who uses a scope. Spotters carry a machine gun in case the militants discover their position. The pair will sometimes watch their target for hours. The spotter is essential because he keeps the sniper up to date on the location of the target and specific details. The sniper fires after exhaling for seven seconds – or until their lungs are empty and they are at their calmest. The elite Canadian sniper was so far away that the bullet took almost ten seconds to reach its target and was travelling at 792mph Then they fire and inhale immediately. The spotter will immediately inform them if they have hit the target. If they have missed they have a few seconds to quickly adjust before they are noticed and can try to hit the target again. The Canadian shooter is part of Joint Task Force 2, which deals with counterterrorism, sniper operations and hostage rescue. Last night a military spokesman said the task force did not carry out patrols with leading combat troops but was there to 'enable the Iraqi security forces who are in a tough combat mission'. The spokesman said: 'This takes the form of advice in planning for their operations and assistance to defeat Daesh through the use of coalition resources.' The sniper took the title from Briton Craig Harrison, who killed two Taliban machine gunners from more than a mile and a half away in November 2009. The Canadian Special Operations Forces Command confirmed the new record-holding sniper 'successfully hit a target' from 11,614ft away, beating the previous target by 3,494ft. Corporal Harrison was using the Army's most powerful sniper weapon, the British-built L115A3 long range rifle. It took six seconds for him to find out if his shots were successful. The Household Cavalry veteran opened fire after his commander and Afghan soldiers were attacked during a patrol in Helmand Province.

Bullet dropped from the guns plane 320" or more than 27ft. There is a lot of calculating going on.
Yeah. But that's what dope cards are for. The coriolis effect has to be factored in after about thirty-three hundred yards. And 792mph is getting close to subsonic. But the toughest part of the shot, imho, was finding a target that would sit still for the ten seconds it took for the bullet to find him.
Or you lucky enough that they move right back to the spot in 10 seconds. You think his buddies freak after seeing him explode and 10 seconds later hear the shot! LOL
Not quite that dramatic. : ) This bullet at 792mph was flying just a bit faster than the speed of sound (767mph). So they would have heard the shot less than a half-second after their fellow-terrorist went all squishy. Probably more like a quarter-second. Hmmmm...interesting. 11,614ft ÷ 1125 feet/second (speed of sound) = 10.3235 seconds (for the sound wave to arrive) (792mph × 5280ft) ÷ 60minutes ÷ 60seconds = 1161ft/second 11,614ft ÷ 1161 feet/second (speed of bullet) = 10.003 seconds (for the bullet to arrive) So it took the bullet 10.003 to travel that distance. Yet the article says it took just under 10 seconds. Hmmmm...maybe I missed something, eh? Anyway, the bullet was traveling at 1161 ft/second and the speed of sound is 1125 feet/second. So over a time span of 10 seconds, the bullet would gain 36 feet/second over its sound wave, making the bullet arrive in 10 seconds and the sound of the gunshot arrive .3 seconds after. Anyway, I was curious and those are my numbers. Anyone see a mistake? Certainly, I am no expert. Perhaps I am off but not by much (I hope).

I have no idea where they got that speed. It comes out of the muzzle at 1800mph. Granted, from that point on it slows down
I thought the sound wave travelled with the bullet. Meaning if you're on the receiving end, you hear the crack of the bullet followed by the gunshot.
Aerodynamics state that the drag imposed on an object increases by the square of it's speed. So the force slowing a bullet traveling 1600 MPH is 4x the strength slowing a bullet going at 800 MPH. This means the bullet speed slows dramatically right after leaving the muzzle, but the deceleration eases up quickly as the bullet slows. The end result is a trajectory curve that is rather straight for about the first half of it's flight, but then curves much more strongly on the second half of the flight as the ratio of horz speed and vertical speed comes closer to par. That is of course another factor for snipers (and long range artillery shooters) to take into account.
