The bullets are the same, what is different is the pressure ratings for the 2 cases, 5.56 has a higher pressure level when fired. As for shooting 5.56 in 223, you can but not recommend long-term. However there is also 233 wyld that can shoot 5.56 more regularly since it is designed to handle it.They sell shell casings, there are no 556 ony 223 cases? I thought you can shoot .223 with a 5.56 barrel but you cannot shoot 5.56 through a .223 barrel. So is it the bullet itself that is different thus why its a no no to shoot 5.56 through a 223 barrel?
