I remember which video you are speaking of. And you are correct. But I would point out a couple of things;
1. the post was asking about 7.62x39 vs 5.45x39 and that was what I was addressing, not 5.56 vs 5.45. 7.62 will certainly carry your liability further outside the house than 5.45 in most circumstances
2. I have seen 5.45 yaw much sooner than that shown in the video. I don't think these instances are that rare either. I do not have scientific data to support my views, as I said in my original post. Just my two cents worth.

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
just got to get a 74,although I'll have more 47's because the 30 caliber projectile will plow through about the same things but cause more damage fron the mass, watched the AR vs AK test on cinder blocks,I was sold,then ya gor the PSL but can't go above 148 gr projectile because it's a cheap gun and can't handle the recoil and it will go through anything, well most anything we ought to be shooting at.
