Hello, I'm an expert in firearms and ammunition. When it comes to the .223 Remington and the 5.56 NATO, there's a common misconception that they are the same, but there are actually some differences between the two.

The .223s are loaded to lower pressures and velocities compared to 5.56mm. Due to its lower pressure, you can safely fire .223 Rem. ammunition in a 5.56mm chambered gun; however, the same cannot be said in reverse. The 5.56x45mm ammo creates a higher pressure.
