The .223 chamber won’t permit for a similar growth that the 5.56 chamber affords. This will shortly result in a dramatic spike in strain.
This overpressure could cause severe issues. The elevated strain could cause the brass case to develop an excessive amount of, presumably resulting in a ruptured case. A ruptured case can then end in sizzling gases and particles being expelled backwards by the motion of the firearm. The result’s a harmful state of affairs that may injure the shooter and/or severely harm the firearm.
