5.56 is higher pressure.
You can shoot a .223 in a 5.56 but not the other way around.

You're too lazy to type that sentence in Google and read, but you expect someone here to take the time to type out a long reply covering the topic.

5.56 also has a longer throat in the chamber.

Ammo or chamber specs? 5.56 NATO usually runs slightly thicker brass so case capacity is slightly less. 5.56 chambers often are cut for a longer freebore and leade for cycling reliability under adverse conditions.
