You can fire the .223 Remington in the 5.56 NATO but not the other way around. The .223 Wylde is a chamber that allows the firing of both; there is no such thing as .223 Wylde ammunition. .223 Remington and 5.56 NATO are the standard rounds for most AR-15s. They have many advantages over other rounds as their smaller size makes them lighter to carry, less expensive, with lower recoil. This makes them great to practice with especially at short to mid-range. They excel at varmint hunting and are great for home defense. The main difference between the two is that the 5.56 was designed for the military and works better with the rapid firing of large amounts of ammunition while in combat.
