Are .223 and 5.56 the Same?
While the .223 Remington and the 5.56x45mm NATO cartridges have effectively the same cartridge dimensions, the 5.56 is loaded to higher chamber pressures and 5.56 chambers have ever-so-slightly different dimensions. Also, 5.56 cartridges are typically made with crimped primers that can be a bit more difficult to remove. The bottom line is while they are similar they are not exactly the same; best practice is only to shoot what your barrel stamp indicates.
