This is dangerous.

TL;DR:

You can use .223 Remington in a rifle built for 5.56x45

You should never use 5.56x45 in a rifle chambered for .223 Remington

Are you worried about the pressure? The round will absolutely feed.

Yes, of course I'm worried about the pressure.

You can also feed and fire a .300 blackout in a 5.56 rifle/barrel, it will just destroy the weapon, and maybe your body if you're not lucky.

Yeah, that comes down to knowing your weapon. You can always over load the powder.
