[QUOTE="Perplexed, post: 1489107, member: 7157"] I'm not so sure about this. There was a comparison made a few years ago between an AR and an AK-74, and the test was videotaped. I can't find it online just now, but the authors shot the AR through a frame with squares of wood spaced slightly apart. IIRC, the 5.56 round penetrated 6 or 7 of the boards before being stopped, while the 5.45 round went through 12 boards before yawing out of the frame, clipping the 13th board on its way out. The penetrating power of the 5.45 round was an eye-opener. Keep in mind the core of a surplus 5.45 round is a steel rod, whereas a typical 7.62x39 round is lead-cored. Less deformation, more penetration, right? ETA: On second thought, the 5.45 round is a lot lighter than the 7.62 round. So I'm probably talking apples to oranges ;) [/QUOTE]
