The problem is not that 308 is a better round than 223, but that the army uses a small grain steel core bullet. A 223 moving at arond 3000ft per sec with a steel core is designed to pentrate a flak vest and still provide leathality to the target. Further, steel cores where inserted to stop the use of lead. Any good deer hunter or soldier can sit down and tell you why a fast moving bullet with a solid core is bad for bussiness. Personall I hunt with a 257 weatherby mag. IT is 25 caliber bullet on a 7 mag casing. It moves with a 100 Seirra Boat tail at about 3700 FPS. With that kind of speed and a FMJ bullet, little bambi dosen't know its been shot, and even through the vitals can run a hell of along way. However, if you change that to a 117grain Round Nose bullet designed for maximum expansion moving about 3200 FPS, it turns bambis insides to jello. So as a joe carrying my M4, I'm not concerned that I have a 223. I just don't like the grain or type of bullet that we use. If you look at the hydrolics of the AK round agianst the Hydrolics of our standard 5.56mm, you can see the difference of why a small bullet is not problematic.
Its the hydrolic effect that the bullet achevies that is important. Furthmore, when use say that a 308 has better ballistics, thats not what your talking about. What I'm gathering from your conversation is ft pnds of energy delievered of target. Thats only a portion of ballistics. The 308 dose not really have that great of ballistics, their are much better rounds when it comes to that.
