Lahti 20mm vs iMac

Gratuitous use of a Lahti 20mm anti-material weapon. Why? Because big boom. If I got a chance to shoot a Lahti I would but anything in its path just for the huge smile I would have from getting to shoot it.

At $40-$50 a shot? Totally worth it.

RatedR gets to shoot a Lahti L39. Like most of this videos, he is using a high speed camera to give us some great eye candy of the Lahti shooting in slow motion. I love the shot of the muzzle blast and the grass just being kicked up into the lens of the camera.

    Where did you get the $ cost of the rounds? They’re closer to $15 each.

    • Nicholas C

      30 secs into the video, he says “anywhere from $40-60 round”.

      • PK

        My mistake, I didn’t watch the video. I only read the articles. 🙂

        I wonder where he’s sourcing rounds, then. I pay closer to $15 each.

          We need your videos where you blow up stuff, 15$ at the time! 🙂

      $15 per round for percussion primed 20mm Vulcan ammo (like what the Anzio rifle uses) YES. 20mm Lahti ammo, NO. It is a whole different animal and anything less than $50 for original stuff is a bargain.

    Amazing! If anyone ever gets the chance to hold a 20mm round you will think it’s a model rocket. Being able to shoot a Lahti make me proud to be an American.

    What in that monitor could have changed the flight so significantly of so heavy a projectile? After all it is a anti-tank weapon for it to be effective energies must be prodigious.

      I had the same thought, but these computers have a bunch of hardware inside which the bullet has to go through, essentially layers. Every layer of component causes it to deviate slightly, more and more as it goes through. It’s very compacted, full of electronics in there.

      If there are more space inside, where the shrapnel of blown up components could go away from the bullet as it passes through, the bullet would have kept a more stable trajectory. But as seen in the video, it was all encases inside the aluminium case bein the computer.

      Amazing how these things work isn’t it? The 20mm can either reduce a torso to a red mist, or be put of path by a leaf.

      It was good up to BT (fast tank) but not for T34. Kind of futile at the end; you must wonder who was punished more.

      Simple, Hard drive. Look at an iMac x-ray. You will see what I mean.

    Tech support? My Imac won’t start….

  • Vinicius Rosa

    $50 a round ? that’s what you pay for .380 here in brazil !

    I remember back in the late 50’s and early 60.s you could buy one of these for $99. and change. Yea old hunters and hunters sold them, + you could buy ammo and for an extra price you could buy wheels for it. The adds were in the back of American Rifleman and a couple of other gun rags. Hunters Lodge had M1 carbines for $59.95. The rare M14 Artillery model Luger for $89.95, High # 03 Springfield for $39.95 in NRA good condition. Inflation and the laws screwed up the everything. Western Military Arms were selling UD MOD. 1911 A1 new pistols for $54.95. M1 Grands went for $89.95. Walther P 38 Like new were $65.00.

      The dollar is worth about an eighth of what it was then…multiply those prices by eight, and they’re within spitting distance of today’s for comparable guns. Still fun to see, though.

    Do you suppose it voided the warranty? He must not like Apple products. 😉

  • I’ve got a couple hundred iMacs where I work. I wonder if next year’s budget will cover the rental of a L39 and a couple grand worth of ammunition.

    Hmmm…how many iMacs or old Mac Pro towers can a 20mm AT round go through? The world needs to know.
