Canadian Sniper breaks record. What a hell of a shot.   :cheers:  :salute

The 3,450-meter shot, which took about 10 seconds to reach its target, was independently verified by a video camera and other data, the source said.

Yes, we figured the bullet drop would be about 1600 feet, over that distance.

Can you imagine his initial reaction when given the orders,...."You want me to do what?"

Imagine that and he was using a Canuk made weapon!

Sorry morf, the weapon a McMillan TAC-50, is produced in Phoenix, Arizona.

I think the sniper more like said, wtf, I should have gotten a lottery ticket instead.

Even if you manage to compensate for bullet drop, wind etc the bullet dispersion still is bigger than a human so you simply need a good bit of luck to hit.

No to mention a target which is not going to move for 10 seconds, or more.

(cough)

I will say that the Canadian marksman program for our army is world class. I know, I taught it. And to be a sniper in a army team, you have to be marksman qualified to get into the program. The sniper program is two-roles - sniper and spotter. Here's the kicker, if you're a spotter,  you're also a sniper. We train both roles into the same group. So a spotter is also an experienced sniper, and a sniper is also an experienced spotter.  There are no 'just spotter' jobs in a sniper team.  We found that having the spotter understand the stresses of a sniper were helpful in the field so that they knew the challenges of the role - and vice versa.  These kinds of snipers are #3 and #4 on the world's longest sniper shots.

Now, if you're in our JTF special forces, not only are you a marksman and a top soldier, you need to pass our entrance exams similar to the American SEAL team.  So now you've taken our marksmen and top soldiers, and then train them to do spotting and sniping. And in the JTF - we train everyone to do all jobs - radio/comms, sniping, LMG, anti-tank... doesn't matter. JTF all roles are interchangeable. And top it off, over 30% of our Army grunts, have post-secondary education, and all who even enter the army, have to obtain good marks in high school. So our group of JTF soldiers are well educated, cross-roll trained, and are the best of our best.  Now throw those kind of soldiers into our sniper program, we get a 3.5 km kill shot (2.18 miles).

And we're commenting on the fact that a JTF sniper made this shot with pure luck... hmmm.... and strange that the top 5 longest sniper shots in the world, 3 are Canadian... hmmmm :grin:

Not disagreeing with any of that, but Zimme's not wrong about the dispersion.  A fair bit had to go spectacularly right on that shot.

Far as I'm concerned hitting something the size of a 3 ton truck at that range is amazing, nevermind a human.

Oh, there is no way it is pure luck, but there are some things which cannot be controlled by the sniper which have to play along in order for it all to work.

Yes, I noted the top snipers were mostly from Canada.  Not trying to take anything away from the efforts at all.  It is impressive, regardless of the circumstances.

No worries. It's just a testy subject of mine since I used to teach it.

And you're bang on the things which cannot be controlled.  The interesting thing about those .50 calibre strikes, they are one-shot kills as there is so much energy in the bullet. If it strikes your shoulder, chest or leg for example, or even glances off your noggin, it's not pretty.

After 3+k km there arent that much energy left, enough to be lethal but prob less than a .30 at point blank range..

If I knew the specifics about the bullet round and the exact model of the TAC-50 used, we could crunch the numbers pretty easily.

  We get lots of practice shooting moose and squirrel! :devil



   I was under the impression the Mac 50 was built in Canada,my bad!

If I make a number of assumptions (647 gr round, 823 m/s muzzle velocity, 0 wind, moderate temperature, 2000 feet elevation), then the energy/force at impact would be around 745 joules (550 ft/lbs), with a velocity of around 190 m/s.

I think that would sting quite a bit. :)

My numbers may be a bit conservative.  Maybe due to the bullet drag coefficient.  I took a guess at that at 0.5.

EDIT:  Yes, my *guesses* might be close, but I am only coming up with a distance of just less than 2 miles at 10.5 seconds of flight time.  So I am definitely a bit conservative on the above numbers.

3,700 yards... That's what this is for.....

Yeah, I am not so sure about the precision of that weapon there Widewing. :D

Both, in terms of accuracy and collateral damage.

With a lethality radius of about 90 feet, precision is of lesser importance to the shooter... Now, the poor buggers around the target person might feel otherwise...   :O

Also, you could get 6 or more in the air before the bad guys know the first one is inbound...

That was a remarkable shot... Just to get within 10 yards is amazing. Great calculation and the stars aligned for him as well. As for the bad guy... Everybody gets dead. It was surely his day.

750 grain Hornady A-MAX VLD round - he used a Schmidt & Bender 5-25x56 PMII telescopic sight.

That makes a big difference.  I was using a Barnes round.

That puts the velocity of the round at about 249 m/s, at impact, with an energy/force of 1,513 joules (1116 ft/lbs).  Oh yeah, that would hurt.

That wouldn't buff out easily.

If he was wearing denim I'm sure it would be fine.  :devil :bolt:

Can't get over how well the .50 carries energy.  I get the math, but it's still amazing to me.

Not all .50's are equal.  Just an example, but the drag coefficient for that round is about half of the Barnes rounds.  The Hornady round is a pretty spectacular round in this caliber.
