Is it true that I can safely fire .223 in a gun chambered for 5.56?
I don't mean in a 'yeah it'll fit and fire but probably shouldn't' sense, but more in the 'you can actively shoot either cal through the gun like it was normal to no ill effect'.

Yes, it is perfectly fine
Doing the opposite is not
yes, when in doubt, RTFM.
it's totally fine
the other way is actually pretty much okay too actually

No, it isn't. Depending on the load, 5.56 can VASTLY exceed the pressure for a .223 chamber and bork up everything.

you're right, let me revise, it's totally okay 99% of the time

is LG still charging $100 for a brick of shitty 22lr? ive vowed to never visit that site again.

Dimensionally, they are identical, so it will chamber just fine. The .223 is actually lower in pressure than the 5.56, so there's no danger of a catastrophic failure. 5.56 in a .223 may give you some issues, though.

no idea, I prefer to buy my ammo local, when I can find it

I used to go local, then I realized that I was paying nearly twice as much for ammo. I'm so impatient I can't wait, but since I have plenty of ammo I can probably order online now

Noguns pls go.

Try again cannon fodder
I've read that 5.56x45 has a shorter throat and higher pressure than .223. Has anyone ever seen a chamber burst shooting 5.56 in their .223 gun?

what is this, canada?

The pressure can be insanely higher. There's no standards for 5.56 - mighr as well be wildcat.
However, the odds of having such a tight fitting, low pressure resiliency .223 barrel while also having a commercially purchased high pressure 5.56 round are pretty low. It's possible, but uncommon.
