Needless to say, Mikhail Klashnikov was interviewed and was very dismissive of the "toy" bullets - if memory serves, something about the advantages of being able to shot through light cover. Note, the switch to smaller calibre has nothing to do with trying to wound rather than kill, (which obviously is more of a strain on the opposing army - wounded have to be treated, whereas dead can just be buried), but for more pragmatic reasons - each grunt can carry more bullets, have a lighter gun that is more accurate.
