Physics is a real jerk. Once a bullet travels past a certain distance, it stops being a projectile and starts being a victim of the environment. Gravity pulls it down. The rotation of the Earth pulls it sideways. Humidity thickens the air like invisible molasses. This is the reality behind the longest sniper shot in history, a feat that sounds more like a tall tale from a bar than a documented military record.
In May 2017, a sniper from Canada’s elite Joint Task Force 2 (JTF2) pulled the trigger in Iraq. The bullet traveled 3,540 meters. That is roughly 2.2 miles. To put that in perspective, if you stood at one end of the Las Vegas Strip, you’d be aiming at someone past the halfway point of the entire boulevard. It’s a distance so massive that the target wouldn't even hear the shot. They'd be dead before the sound waves even covered half the distance.
People think sniping is about a steady hand. It’s not. At these distances, it’s mostly math. It's about accounting for the Coriolis effect—the literally spinning of the planet beneath the bullet while it’s in flight. If you don't calculate for the Earth's rotation, you miss by feet, not inches.
The Record-Breaking Shot in Iraq
The JTF2 sniper, whose name remains classified for obvious security reasons, used a McMillan Tac-50. It’s a beast of a rifle chambered in .50 BMG. He was perched in a high-rise building, looking down on ISIS insurgents. When he fired, the bullet stayed in the air for nearly ten seconds. Ten seconds. Think about that. You can take a sip of water, check your watch, and sigh before that round impacts.
The shot was verified by video and other data, shattering the previous record held by British sniper Craig Harrison. Before the Canadians took the top spot, Harrison held the title for a 2009 shot in Afghanistan at 2,475 meters. The jump from 2,475 to 3,540 is staggering. It’s not just a marginal improvement; it’s an outlier that defies most ballistic charts.
Why the McMillan Tac-50?
You can’t make the longest sniper shot in history with a standard hunting rifle. The Tac-50 is a bolt-action monster. It’s designed specifically for long-range interdiction. It uses a 29-inch heavy barrel to ensure the bullet leaves with maximum velocity and minimum wobble.
But the rifle is only half the story. The ammunition is "match grade," meaning it's manufactured to tolerances so tight that every grain of powder is weighed. A microscopic difference in the amount of gunpowder could mean the bullet drops an extra ten feet at two miles out.
The Science of the "Impossible" Shot
Most people imagine a sniper looking through a scope and seeing a clear person. At 3,500 meters, a human being is smaller than the thickness of the reticle lines in your scope. You aren't really "aiming" at a person; you're aiming at a patch of sky above and to the side of them, hoping your math holds true.

Let’s talk about the variables.
The air isn't empty. It’s a fluid. Temperature changes the density of that fluid. If the sun comes out from behind a cloud while the bullet is in flight, the air warms up, it becomes less dense, and the bullet rises. It’s called "vertical stringing." Then there’s the wind. Even a slight 5 mph breeze, something you’d barely feel on your cheek, can push a .50 caliber bullet dozens of feet off course over a two-mile trek.
The spotter is actually the MVP here. In the case of the longest sniper shot in history, the spotter had to calculate the density altitude and the specific "drag curve" of the 750-grain Hornady A-MAX bullet. They use Kestrel weather stations and ballistic computers, but there's still a "gut feeling" involved. You have to read the "mirage"—the heat waves rising off the ground—to see what the wind is doing midway through the flight path.
The Controversy and the Skeptics
Whenever a record like this is broken, people get skeptical. Some veteran snipers from other nations questioned the JTF2 claim. Why? Because at that range, the "probability of hit" (PH) is statistically near zero. It’s what ballisticians call a "lucky" shot.
That’s not to say it was an accident. The sniper intended to hit the target. But at 3.5 kilometers, the "grouping" of even the best rifle in the world is larger than the target itself. To get a hit, the shooter needs perfect execution, perfect math, and a little bit of grace from the wind gods.
The Canadian Special Operations Command stood by the record, stating that they have the data to prove it. It wasn't just a claim; it was an operational necessity. They used the long-range fire to disrupt an ISIS attack on Iraqi security forces. Instead of dropping a bomb and potentially killing civilians nearby, they used a single, precise (if incredibly lucky) bullet.
Previous Records: A History of Distance
- 2017 (Canada): 3,540 meters in Iraq (JTF2 Sniper).
- 2009 (UK): 2,475 meters in Afghanistan (Craig Harrison).
- 2002 (Canada): 2,430 meters in Afghanistan (Rob Furlong).
- 2002 (Canada): 2,310 meters in Afghanistan (Arron Perry).
- 1967 (USA): 2,286 meters in Vietnam (Carlos Hathcock).
Look at that jump from Hathcock in 1967 to the modern era. Hathcock used a Browning M2 machine gun with a scope mounted on it. It’s insane. He held that record for 35 years. It took the invention of dedicated long-range calibers and laser rangefinders to finally dethrone him.

What Most People Get Wrong About Sniping
Movies are the worst at depicting this. In the movies, the sniper holds their breath, the heartbeat thumps in the speakers, and they click the trigger. The target falls.
In real life, especially regarding the longest sniper shot in history, it's a team sport. The sniper is basically the "trigger puller" for the spotter’s brain. The spotter is yelling out adjustments: "Left three-six-zero! Up two clicks!"
Also, the bullet doesn't travel in a straight line. It’s an arc. At two miles, the bullet is essentially falling out of the sky by the time it hits. It's not "zapping" the target; it's more like a very heavy, very fast piece of lead crashing into them from a high angle.
And let’s be honest about the lethality. A .50 BMG round is designed to punch through engine blocks. At 3,500 meters, it has lost a lot of its velocity, but it’s still moving fast enough to be lethal. It still carries more kinetic energy than a .45 ACP handgun does at point-blank range.
The Ethical Debate of Extreme Distance
Is there a point where the distance is too great to be ethical? Some military theorists argue that taking shots at these ranges is a waste of ammo or a risk of missing and hitting the wrong person.
However, the JTF2 shot changed that conversation. It proved that with modern optics—likely using something like the Schmidt & Bender 5-25x56 PM II—and advanced ballistics, "area denial" can happen from miles away. It’s a psychological weapon. Imagine being an insurgent and your comrade just drops. No sound. No muzzle flash. No warning. You are being hunted by someone you can’t even see with binoculars.
The Canadians have a weirdly high number of records in this category. People joke it’s because they have a lot of open space to practice, but the reality is their training program is one of the most rigorous in NATO. They emphasize the math. They emphasize the "cold bore" shot—the first shot from a clean, cold barrel, which is the only one that truly matters in a real-world scenario.

How to Understand the Ballistics
If you want to understand the longest sniper shot in history, you have to look at the "transonic" zone.
When a bullet is fired, it starts out supersonic (faster than the speed of sound). As it travels, air resistance slows it down. Eventually, it hits the "transonic" stage where it slows to the speed of sound. This is where most shots fail. As the bullet crosses that threshold, it encounters "buffeting"—turbulent air that can knock it off its stable spin.
The JTF2 shot was deep into the subsonic range by the time it hit. It survived the transonic transition and stayed stable. That is a testament to the quality of the barrel and the aerodynamic efficiency of the bullet.
Practical Insights for Long-Range Interest
If you're fascinated by this, you don't need a .50 caliber rifle to start. Most people will never even see a 3,000-meter range, let alone shoot on one.
- Master the 100-yard basics. If you can’t put five bullets in the same hole at 100 yards, distance will only magnify your errors.
- Learn Ballistic Coefficients (BC). This is a number that tells you how well a bullet cuts through the air. High BC is king for long range.
- Get a Ballistic App. Apps like Applied Ballistics or Hornady 4DOF allow you to plug in your local weather and see exactly how much a bullet will drop.
- Study the Wind. Start "calling" the wind when you walk outside. Is that a 5 mph breeze or 10? Look at the trees. Look at the grass.
The longest sniper shot in history isn't just a statistic in a book. It’s a landmark of human engineering and physics. It represents the absolute limit of what a human can do with a mechanical tool. Whether that record will be broken again soon is anyone's guess, but with the advent of "smart" scopes and guided small-arms munitions, the three-mile shot might not be as impossible as it sounds.
Next time you see a clear horizon, try to pick out something two miles away. Then imagine trying to hit a dinner plate sitting on that spot while the world is spinning, the wind is blowing, and your own heart is trying to throw off your aim. It’s not just a shot; it’s a miracle of geometry.
To truly appreciate the scale, look into the specific history of the McMillan Tac-50 and how it differs from the Barrett M82. The Barrett is semi-auto and great for volume, but for world-record precision, the bolt-action Tac-50 remains the gold standard. Studying the mechanical lock-up of bolt-action rifles will give you a deeper understanding of why this record sits with the platform it does.
