However the round used is virtually identical to a 5.56 NATO... which is an assault rifle round.

Lol hell no.
First of all, there's no such thing as an "assault rifle round." It's just a regular rifle round.
Secondly, civilian .223 isn't remotely like military 5.56 NATO. Civilian .223 is usually just 55 grain full metal jacket rounds. Military 5.56 is usually 62 or 77 grain, and can be anything from full metal jacket, to armor piercing incendiary, to tracer.
.223 is just a small game hunting round.
Yes there is. An intermediate sized round, smaller than a full battle rifle cartridge. Source.
Average grain is 55 for .223 fmj and 5.56 is most common in 55 and 62
Fancy bullet types aren't relevant here.
Considering you can interchange them in a weapon chambered for 5.56 I'd say they're pretty damn similar.
