The 5.56 NATO round is a tad longer, about 0.4mm longer; but that has nothing to do with why you shouldn't intercnahge them. You shouldn't mix them because a 5.56 NATO chamber has a longer leade (cartrige mouth to rifleing engagement), a .223 chamber has a shorter leade. Shooting .223 out of a 5.56 chamber will not lead to any problems other than less-than-stellar acuracy, however, usind 5.56 in a .223 chamber WILL lead to premature wear out of the chamber and parts.
