A rifle with a 5.56x45 chamber can utilise .223 Remington cartridges. A rifle with a dedicated .223 Remington chamber cannot accommodate 5.56x45 cartridges. A rifle with a .223 Wylde chamber can accommodate .223 Wylde, .223 Remington, and 5.56x45, but neither a rifle with a 5.56x45 or a .223 Remington chamber can accommodate the .223 Wylde cartridge.
556 - 223 = 333
.223 Remington can be cycled in a 5.56x45 rifle; 5.56x45 should not be cycled in a .223 Remington firearm.
Yes it does, unless your barrel is stamped .223 .
if it is a 223 cal, then yes
Yes there is a difference. They are physically the same size casing, but the 556 military rounds' chamber pressure is ~10,000 psi higher then 223. Military rifles generally have chambers with a different throat configuration than normal sport 223 rifles. This being said, I would not recommend shooting 556 unless your rifle was designed for the higher pressures.
Dimensionally similar, but they are not exactly the same. A firearm with a 5.56x45 chamber can accommodate the .223 Remington cartridge, but a firearm with a .223 Remington chamber cannot accommodate the 5.56x45 cartridge.
No. They have matching dimensions, but differ in other areas, such as neck angles. .223 ammunition can be safely fired in a 5.56x45mm chamber; 5.56x45 ammunition is not recommended to be used in a .223 Remington chamber.
No. The two rounds are not interchangeable.
lighter bullet and more ammo can be carried as opposed to the 30/06 or 308
I assume that you are referring to 5.56mm in your question?,if so yes you can shoot this ammo in your rifle.The 5.56mm is the metric designation for the .223 Remington cartridge.
Yes, .223 and .223 Remington (often abbreviated as .223 Rem) refer to the same cartridge. The term ".223" is a shorthand designation, while ".223 Remington" specifies the manufacturer and is the official name of the cartridge. They are typically interchangeable in firearms designed for .223, although it's important to note that .223 Remington is loaded to higher pressures than the .223 Wylde or .223 Remington match cartridges. Always check your firearm's specifications to ensure compatibility.
Yes the mags work with both ammos. You can not tell the difference in the two by looking at them.
