50 BMG Armor Piercing Incendiary Vs. Engine

Serbu_BFG-50A_2_335455

Do not ask “why”, instead ask “why not”?. Our good friend Andrew takes a Serbu BFG-50A, loads it up with .50 BMG Armor Piercing Incendiary rounds and sees what kind of damage it can do to a large engine. Not to ruin the video for you, but the answer is quite a lot!

    Hm. Who would have thought an anti-materiel rifle would do that to… materiel.

    • TheNotoriousIUD

      I thought they meant like cotton or polyester..?

        The difference between material and materiel 😉

    My interest isn’t so much in the damage it does to the engine, that’s obvious, but what about behind the engine? Since it’s common knowledge that an engine block can be used for cover if you are being shot at, it would be nice to see how many .50 rounds (if any) penetrated the entire motor. I didn’t see any dirt flying up near the back stop and it appeared that the engine was stopping the rounds but I couldn’t tell for sure.

      at 3:15 he states that “the rounds did not penetrate the backside.”

    • BKE Evers

      He didn’t shoot the same spot over and over. He stitched it horizontally. I bet 8 shots within 1 MOA of each other would have drilled through that block at 200 meters.

    This is like watching a History Channel documentary on the .50 BMG.

    Another semi-useless test.

    As mentioned in the 50BMG vs engine a few days ago, AP rounds have maximal effect past 200 yards, someone should do the tests at that range.

    In any case, it will not zip through the engine (API has about 1in penetration on steel at 500 yd, depending on angle, type of steel, etc etc) – but ‘collateral damage’ (spall, fires and the like) should be enough to kill people inside the vehicle.

      How the incendiary round that did not pass through engine block can burn people inside?
      Also spall effect is quite skeptical.
      I heard about such effect with HESH cannon rounds, but they cause shrapnel over barrier with their massive high explosive pressure at point blank.
      I don’t think kinetic impact (and incendiary/explosive effect) of a .50BMG round will reach such high amount of energy.

        Watch some thermal footage of C-130 strikes. Even with a 20mm and 30mm cannons its pretty much never a direct hit. Its surprised me too, but that is reality.

      • Renato H. M. de Oliveira

        You’re right.
        Would it possibly get the car on fire?

  • Haunted Puppeteer

    Exposed gas tube is a design faux pas.

  • Jeff Heeszel

    I was hoping he was shooting a model airplane engine.

  • iksnilol

    Why do they never test at longer distances? Would be interesting to see how the rounds work at longer distances, both against hard stuff like cars and soft stuff (like ballistic gel).

    That might make it through, but probably just barely. Lol
