The Wound Channel’s Amazing High Speed Armor Penetration Videos

There’s a lot that can be learned by shooting different rounds at various targets, barriers, armors, etc, but the knowledge that can be gleaned from these sorts of tests is limited without the aid of very high speed recordings, which allow us to actually see what is happening when a projectile strikes a target. In recognition of this fact, YouTuber William of The Wound Channel has partnered with Aimed Research, a company specializing in very high speed footage for ballistic research. This gives TWC access to extremely capable Phantom high speed cameras, allowing him to capture high velocity 5.56mm bullets hitting armor plates in slow motion, like in the videos embedded below:

TWC was one of the first civilian outlets to test the much-talked about but rarely-seen M855A1 Enhanced Performance Round, which is replacing M855 in service with the U.S. Army. The channel regularly releases high quality gelatin and armor test videos of various viewer-requested ammunition, as well as accompanying chronograph data. With the addition of high speed footage from a Phantom camera, The Wound Channel will be releasing more excellent slow motion footage of different ballistic tests, William told TFB. According to him, These two videos are just a first taste of what’s to come.

    I love these super slow motion videos. On the M193 video, it seemed almost like .223 level weak sauce. It’s also a bit of a shame they didn’t say what length of barrel they used (I have to assume that it is William’s 16″ AR-15) and apparently didn’t use a chronograph to add some context to the results. I kind of wonder what manufacturer made that particular cartridge, not exactly a bravura performance on their part.

      He did mention that he used a 16″ barrel with the M193. I don’t think M193 is guaranteed to go through AR500 every time, but best to assume it will and find some better cover and use good tactics when wearing it.

      • Yeah, M193 will penetrate AR500 at very high velocities, and 16″ is right about where the tipping point is (M855 will not penetrate AR500, and it’s only a little slower from a 20″ barrel than M193 from a 16″ barrel).

        That means that differences from shot to shot, in temperature, distance, and other factors that affect velocity could mean the difference between a penetration and none.

          Someone in a forum brought up the fact that rifle rounds will probably deflect off of steel plates if they impact at an angle. I have to think that the paxcon lining would not do much to prevent a round from skipping off and still having enough momentum to do damage to your face, bicep, or quad. Every test video shows a straight on impact, so it’d be nice to see a test when they shot plates at an angle.

          Even if that fear is unfounded, I’m still sticking with ceramic.

    Did he mention anything about barrel twist, distance or ammo manufacturer?

  • TWC produces some of my favorite test videos on youtube

    Super slow mo yo!
