5.56mm is the military type of ammunition and is loaded to slightly higher pressures than .223 which is the civilian equivalent. Military specs mean the cases have been annealed, and the primers are crimped in place. These are great for reloading after preparation.

The chambers in 5.56 and .223 are also slightly different. You can shoot .223 in a 5.56 marked barrel, but should not fire 5.56 from a .223 marked barrel unless it is marked .223 Wylde.

Rule of thumb: Barrels marked 5.56 or .223 Wylde will shoot any available ammunition. Barrels marked .223, only shoot .223!
