There are 3 different Chambers in .223 .556. they are all different. .223 is for .223 only. .556 has an expansion area in it. It prevents the extra power from damaging the gun or shooter. .223 Wylde is a special chamber for both. It has no expansion chamber but is made stronger to take the power of.556. .556 is unsafe in a .223 chamber. The expansion space will reduce accuracy with .223 in a .556 chamber. .223 Wylde works equally well with both. No it is not safe to shoot .556 in a standard .223 chamber.
Out of all the stupid people in this world, can you provide at least one documented incident where shooting a 5.56 caliber cartridge in a .223 bolt rifle "exploded" the rifle?
What exactly do you mean by "extra power" of the 5.56 round? Do you mean SAAMI pressures?
The reality is ANY gun shooting the proper round can still go boom in a bad way...
Key question is how many rounds of cheap mil surplus ammo can you shoot through a modern day bolt gun chambered in .223? The reality is you can still be hit by a car crossing the street even though it doesn't happen very often.
