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
No doubt about it. A sniper can put the fear of god into you.
The muzzle velocity of a .50 BMG from a McMillan Tac-50 is 2641 feet per second (1800 miles per hour). My guess is that it took 5-6 seconds to reach it's target. In that period of time, the bullet would drop 400-500 feet.
I read the muzzle velocity is several times the speed of sound, but that the bullet would have slowed to near subsonic by the time it reached the target. Still it's obvious that luck is one of the many factors available. I remember picking off a beer bottle with a heavy caliber handgun from perhaps 100 yards. If you fire enough shots you'll hit your target eventually. All that's required is for the target to be within power range of the weapon used. I'm sure soon they'll have guided bullets where they can train a laser on the target and the bullet will simply hone in on the reflection. The laser will be controlled by a computer that's watching the target via a zoom camera. The rifle will be similarly operated by a computer. All the operator does is sight the target in with a laptop and click the "Shoot" button. Even if the target moves, the laser will adjust, and the bullet will change trajectory to match. Bullets might cost $50 each but with an unlimited military budget, who cares?
32ft per second. Gravity is constant and doesn't care about velocity just time. I notices I used inches instead of feet. It would have dropped 320ft in a 10 sec travel. Thats just crazy! LOL
True. Plus I read that when a bullet slows and passes from supersonic to subsonic, that causes destabilization and accuracy suffers. Why is why there aren't that many long range kills.
Distance (d) travelled by an object falling for time (t): g = 32 feet per second squared. t = 10 seconds. That works out to (1/2)(32)(100) = 1600 feet. If the bullet flight was only 5 seconds, that works out to a "reasonable" 400 foot drop.
Correct but I meant bore sight(my bad for not being more specific) versus actual bullet drop. Both are incredible distances.
I wouldn't know. But i've shot an ai 115a3 and iirc, the muzzle velocity is around 950 m/sec or a couple of thousand mph.
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).
My two sons went to a long-range shooting exhibition where they shot about a dozen rifles set up at different stations. They mentioned one that was "larger than a .30 cal but smaller than the .50. Could have been that one. Anyways, the attendees all got one shot of the Barrett 50. They both said one was enough. Their favorite? The M249 Squad Automatic Weapon.
Not to mention really,REALLY piss you off. In the entire history of the world,the only nations that had to build walls to keep their own citizens from leaving were those with leftist governments.
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
Are snipers using issue M-2 ammo,or are they reloading? I have a hard time believing they are shooting issue loads. At that distance you don't shoot at moving targets. You wait for them to sit. In the entire history of the world,the only nations that had to build walls to keep their own citizens from leaving were those with leftist governments.
That's true,but with a spire point bullet as long as a 50 cal BMG bullet,any destabilization would be MUCH less than typical. Especially if they are handloading and using boat tail bullets. And I can not think of one single reason why they wouldn't be brewing their own loads. In the entire history of the world,the only nations that had to build walls to keep their own citizens from leaving were those with leftist governments.
What's an ai 115a3? In the entire history of the world,the only nations that had to build walls to keep their own citizens from leaving were those with leftist governments.
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.
I think there is some confusion there,but I may be wrong. Having been on the receiving end of sniper fire,I can tell you that you can hear the bullet "pop" as it passes by your ear,but I never once heard the gunshot. Maybe the sniper was using a silenced weapon,but I THINK they were pretty rare on Soviet weapons in 69. Could it be the guy that told you that heard the "pop" of a near miss and thought it was the sound of the muzzle blast? That was one silent goober after he took his shot and missed. He never tried another one. Good thing for him,too. I was plenty pissed because it made me drop my last chocolate bar in the stream I was crossing,and I would have had some fast movers drop some napalm on his ass if he had shot again and I could have located where he was. In the entire history of the world,the only nations that had to build walls to keep their own citizens from leaving were those with leftist governments.
Gee,I wonder why? (G) In the entire history of the world,the only nations that had to build walls to keep their own citizens from leaving were those with leftist governments.
There is something a little wrong with their math, it seems to me. And he shot a guy on a building and ISIS doesn't have any mountain towns it is fighting in (higher altitude might alter a few parameters due to thinner air). The math is close but not quite on. There is some misreporting here. But then do we expect expert ballistics reporting from DailyMail? Probably not since only about .1% of their readers would care at all about precise ballistics.
This bullet apparently traveled only a little faster than the sound wave. But there are other slower bullets as well as much faster bullets where you would have a delay from the time the bullet arrives and when the gunshot sound wave arrives. Apparently this sniper gun fires a relatively large and heavy bullet at a speed just above the speed of sound and it does it very accurately. I think this wasn't an especially fast bullet by military standards. I thought it sounded a little slow, to be honest. But I could easily be wrong. A ballistics guru, I am not.
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.
I wonder if you would even hear the gunshot at over 2 miles away. You almost assume it had to be dead still (if the shot wasn't total pure luck). So a windless day in the desert, a fairly loud and powerful gun, maybe you would hear the gunshot at 2 miles pretty easily but it wouldn't be very loud. I'd have to look up some math on how sound dissipates over distances. I think you'd hear a mild thud in the body, probably with some blood spatter, then a slightly louder popping sound from the gunshot .3 seconds later. You can see I like imagining the effect of this "shot heard round the world" on the barbarian sand-rat and his buddies. We have no idea how loud the gunshot was when the bullet was fired so we can't do a very good estimate of how loud the gunshot would be when the jihadis heard it, .3 seconds after they see their jihad buddy start oozing a lot of blood. The sound intensity drops very sharply after only about 30 feet (sound intensity will decrease by the inverse square of the distance). The decibel level drops about 6dB each time the distance from the gun doubles. 73dB would be a pretty sharp pop, an unmistakable gunshot sound.
I thought it had to be something like that. The "just under 10 seconds" and especially the 792mph was looking kinda fishy to me. Thx.
That's right. The bullet would have left the barrel at approximately 936m/s (3070fps) and about ten seconds later would have been around 2.1 miles away, traveling at about 972mph (1161fps) as it hit its target, according to the story. Give or take local variables.
What action and barrel does it use?' Calibers? If it is a 308/7.62x51 is it virtually useless in the various Shitstainistans. You need the longer belted magnum cases to push the heavy bullets out to maximum distances. The 300,338,and 375 magnums. Long,heavy bullets buck wind better,and retain more energy at long distances. In the entire history of the world,the only nations that had to build walls to keep their own citizens from leaving were those with leftist governments.
Don't know about any of you,but *I* sure as hell don't want to get hit by a 750 grain 50 caliber bullet traveling at any speed that keeps gravity from making it fall to the ground. In the entire history of the world,the only nations that had to build walls to keep their own citizens from leaving were those with leftist governments.
If it took ten seconds, the bullet would have dropped 1,600 feet. Unless it had wings. Then there's windage.
Doing the math, I came to the conclusion that 792mph for the bullet speed is some kind of average speed or estimate. I think it was traveling slower than 792mph when it hit the target. If the shot really took less than 10 seconds as they reported, 792mph is just a little too fast for the math to work.
I wonder just how big a hole it would make in his torso. I'm dubious on the bullet splattering inside his body much, mostly just a big hole front and back with blood spurting out fast. He'd be dead in seconds, I think. Probably paralyzed by systemic shock immediately (unless he was full of adrenaline and his blood fully oxygenated which seems unlikely if he held still long enough to get hit from 2 miles away).
Bolt action. Still using their own flat bottomed, flat-sided receiver, afaik. Calibers are win 308 and .338 lapua, 6.5 creedmore (.260 rem), 300 wsm, etc. The one i shot had a twenty-six inch bartlein 5r barrel, iirc.
Slightly larger than 50 caliber do to hydraulic expansion of flesh. I guess it could be bigger if it hit the breast plate and shatter it because those sharp shards of bones would expand the hole. Mabye not as much as the hydraulic dynamics,but velocity would probably be the biggest determinate. Unless of course it grazed something just before striking bone and hit sideways. If that happened the damage would be pretty spectacular. Bones and bullets are never pretty.

That was my thinking. I wondered if it hit the arm, it would tear away the flesh but if it hit the bone in the arm, it might tear the arm off entirely. A big bullet with a lot of kinetic power. Now I wish we had post-shooting photos so we could see how effective it was.

Again, I could be wildly wrong here, assuming the sniper rifle might emit sound at 140dB from five feet away from the gun barrel (a real loud cannon of a gun/bullet combo) and then dropping to 74dB at 10240 feet, meaning at 11,614 feet it would still be at least 73 dB. I think. Don't quote me for God's sake. LOL distance
