As a firearms expert with extensive knowledge in ballistics and ammunition, I can provide a detailed comparison between the .223 Remington and the 5.56x45mm NATO cartridges. It's important to note that while these two rounds are often used interchangeably in many discussions, they are not identical and do have some differences.

You can shoot 5.56 through your .223 chambered AR-15��but you may regret it. Since 5.56mm Mil-Spec ammo is loaded hotter, it has higher chamber pressure. Built to SAAMI specs, not Mil-Spec, the .223 chamber is ever so slightly smaller than a 5.56 Mil-Spec chamber.
