well he could be complaining about the AP rounds bouncing off the side of m-3's fired from tigers, i have had them bounce off the window frame from my tiger, at the very least you should be ably to blow the drive wheels off an m-8 if not killing it outright yet they sometimes drive right by no damage whatsoever , i have hit m-3's with 5 or 6 shots of AP from a tiger in the sideplates and watched the rounds bounce off, one time bouncing off to kill a jeep right next to it! that was funny!!
