Exclusive: Mark and Sam’s 4384 yard shot (4008 meters) with 375 GIBBS

You have to love the recent records and record attempts to shoot and hit further out, from all around the Globe. I hope this continues in 2017 an onward.

TFB recently reported from Finland and France and now it’s time for some long range shooting from down under, Australia.


Wonderful “shooting range” in Australia

In all cases, it seems either the .375 CheyTac or the .408 CheyTac is the cartridge to accomplish the mission.

This time it’s a “new” caliber .375 GIBBS, more details below.

TFB reached out to Mark and Sam to congratulate and to get some more details and background, and here is their story:

“We are husband and wife and have the pastime of ELR Shooting.  We work very well together.  Sam also shoots but is at home behind the spotting scope.  My job of shooting is greatly enhanced by my mechanical understanding and ability to modify my rifles to shoot as I want them too.


We do a lot of extreme shots with all different calibres, the longest shot we had previously made was at 2 miles / 3561 yards with our SAKO TRG 42 in 338LM. This was achieved as our 2 man team, spotting from the shooting position onto a 24” x 24” steel target (600mm x 600mm).  This brought on the urge to go further, what seemed like the next step was then 4000 metres.  With that goal in mind we chose the .375 Cheytac as a good choice.  This actually turned into a .375 Cheytac Improved, something we have dubbed the .375 GIBBS, referring to the original case from the Cheytac.


The distance and the calibre/rifle took a bit to work out with bullet style, load etc.  As did finding the right condition to spot the shot in.  We had all this sorted ready to do this shot at the beginning of the year (2016). 

But as fate would have it, it rained.  And, unusual to our area, it kept on raining, so we had to wait.  Winter came, crops came, then Spring, then Summer and approximately 8 weeks ago harvest came, so……. Then we are on! 

First attempt on target we reconfirmed all our data, but found vision very difficult shooting in the morning sun, just very hard to see.

So we changed plans, we shot in the evening, using the sun behind the target to highlight the impacts.  The day of the shoot,  we really felt we had things where it was going to be “doable”  that is 4000 metres onto a 24” plate. 


The shot went well, very close to target right off the bat, wind was changing a little, so had a bit of working that out with over 10 seconds of flight time.  We had it all under control, ready to hit, wind was steady, two shots in a row verified shot placement, squeezed the trigger, waited for impact, “no see”, but it was a HIT!!

We just could not see, because we were looking at the dark side (shadow) of the target.  I had not considered that we would not be able to see the “hit”.  Anyway when we got to the target, we had hoped (but did not know) we had a hit until we got to the target. 

We had just achieved a hit at 4384 yards (verified with GPS, Google Maps and iPhone measuring app) with only a 2 man team, spotting from the shooting position, using a 24” x 24” steel target.”


It must be a great help to have an understanding wife when purchasing a new rifle, mount or optic…

My question was how many shots they needed before the first hit, and the reply was: “from memory we had 14 shots in total before hit. Took us a few to get on to the wind conditions.”


In the latest article, I begged for some uniformity so that it’s easier for a third party to understand the facts behind the shot(s). How do you measure the distance, how many bullets fired etc.? Here you can see the distance being measured, and the text above gives more background.

Details of the Rifle:

The 375 GIBBS (Custom Built Extreme ELR Rifle), which is their own name for the cartridge.

They rifle is a 375 CheyTac with an improved chamber.  The chamber has been taken out a little bit, but it’s using the 375 Cheytac bullet.

In detail, it’s a 350 grains solid copper bullet.

According to the interview at the end, they need to get down to shooting a 1/3 MOA group to “get this thing“.

Below: HIT! (top right corner)


Below: Not sure what material this 24″ plate is made of, but after 4 kilometers the bullet still made a substantial impact, but without penetrating.


Below: Base camp. The target is over 4000 meters away. That’s almost 2,5 miles away.

  • Harry’s Holsters

    WOW! that’s a shot! How many MOA was built into the Base?

    It looks like the line of sight would be obscured by the barrel!

    • Amanofdragons

      Per the article , looks like 60

  • Martin Grønsdal

    This will end when I’ll go to the space in a balloon, armed with my .22 Walther P22, and film hitting the earth from 20K altitude.

    • Dougscamo

      Nope…..someone will figure out a way to take a howitzer and make a shot from 5000 miles….don’t know what that is kilometers….sorry…..

      • Martin Grønsdal

        Hehe. You’re right…

    • Ed Forney

      I’d like to use my P22 as a target !!

      • MadOnionSix

        Same here, hate the piece of cr…

        • Ed Forney

          I could throw a rock at a target, and be more accurate.

  • Swarf

    I wish that wasn’t such an expensive pastime. It looks so… zen.

    • A.WChuck

      You could try extreme long range air rifle shooting. It is bit easier on
      the budget and the “extreme” ranges are much shorter. However, with the
      lighter and slower projectiles the difficulty level is similar.

      • Ed Forney

        Was next to a guy shooting a 32 caliber air rifle, with a 4000 psi ( I think) tank. Very impressive, but very expensive as well.

    • StraightshooterJeff

      You can replicate such shooting over shorter ranges using a .22RF.

  • mikee

    I once fired fired 3 rounds of 105 mm AP rounds from an L7A1 gun in a Leopard AS 4 tank at steel targets at 5K in good atmospherics. One missed. Does this rate as a record to???? Yea right !!!

    • Anonymoose

      From an unguided shoulder-fired weapon, though?

  • Ken

    I’ve been following their YouTube channel for quite a while now. A lot of the questions you raise are answered in their previous long-range shot videos. I don’t know his background (someone has said Aussie special forces, but who knows) but they obviously spend a boatload of time working up loads, doing the math on the shots, etc. I’m constantly amazed by some of their shots. He even did some fun long-range stuff with a lever action 45-70.

  • gunsandrockets

    This makes me extremely curious about old military bolt action rifles which typically had open iron sights calibrated to a maximum distance of 2,000 meters (or more!). Has any gun nut recently recorded any test shooting of an old military rifle such as a K98, firing the appropriate military style heavy ball ammunition at the distance of maximum sight setting? Yeah, I expect such fire would result in more of an area fire effect than point fire, but uncovering that data would be fascinating.

    • Anonymoose

      Those are for volley fire at those ranges, though. You’re not going to hit squat past maybe 600 yards even with good peep sights no matter how good your eyes are or how good your barrel-floating/bedding is.

      • gunsandrockets

        Considering their success with the .45-70 at 1000 yards (standing position, open sights, high wind), I suspect you are overly pessimistic.

        • Paul White

          Good lord. I should just hang up and go back to bb guns cause he just won guns.

        • Tassiebush

          It reminds me of those tales of bison hunters and some of their extreme range shots.

    • Klaus

      Check out Rex reviews on YouTube. He’s hitting @ 996 yards with a Mosin Nagant and irons.

    • FarmerB

      Look at the Long Range Shooters of Utah on YouTube. Guy whacking stuff with a bog standard K31 Swiss at over 2000 yds.

  • lansns

    Don’t know what I’m talking about, but wouldn’t shooting in cold and higher altitudes be easier? Thinner air (higher velocities) and less moisture? (higher humidity would decrease velocity and increase sudden temperature variations)
    In this hot Australian place, you’d have hot air moving around everywhere even if there was little if any wind.

    • RSG

      Cold=slower velocities. Hot=faster

    • FarmerB

      Altitude makes it easier – less air. Cold makes it harder – less velocity and denser air. I like mountains since they tend (mostly) to moderate the wind, and you get the altitude, although wind flags cannot be used across valleys, etc. plus you get more distance for the slope on your optic.

      Shooting in the flat, hot Australian outback is very challenging mainly because the damned wind NEVER stops. Unless you’re shooting at night, when it’s very much calmer.

  • FarmerB

    I wonder what the zero on that rifle is 🙂
