there are quite a few threads on 223 vs 5.56, the conclusion is "you read and reach your own", I have shot 5.56 in my savage.
You heard wrong. I strongly recommend to NOT shoot 5.56 in a .223 chambered firearm.

5.56 chambered firearm: can shoot either 5.56 or .223

.223 chambered firearm: ONLY .223.

Same goes with 7.62x51/.308.

Only shoot .308 in a .308 chambered firearm.

A 7.62x51 chamber can shoot both.

And it's not that they will function, but its that they both can SAFELY.
