So in the concrete block test, 5.56x45mm and 7.62x51mm were both able to penetrate the block but both had little energy left over after passing through. This time around, let's say the "cover" in question is a brake disc. Given that M193 is known to penetrate steel Level III plates at close range (link) and M80 ball cannot, which will win? M193, M855, or M80? 16" AR and 22" M1A. Distance will be about 25 yards. Brake disc is the combination rotor and hub from the front axle of a 2004 F-150. Make your predictions before you watch the video.
