The 5.56 cartridge has a different neck angle from the .223 Remington, generates higher chamber pressures, and has different weight projectiles available. .223 Remington can be safely cycled through a rifle with a 5.56 chamber, but it is not recommended to use 5.56 ammo in a rifle with a .223 chamber.
.223 Calibre although .223 Will fit on a 5.65 mm, a 5.65 mm Will not fit in a .223 calibre chamber.

Chamber pressure is dertmined by the cartridge. The max standard pressure for .223 is set by SAAMI at 55,000 PSI.
The 5.56 NATO round is a tad longer, about 0.4mm longer; but that has nothing to do with why you shouldn't intercnahge them. You shouldn't mix them because a 5.56 NATO chamber has a longer leade (cartrige mouth to rifleing engagement), a .223 chamber has a shorter leade. Shooting .223 out of a 5.56 chamber will not lead to any problems other than less-than-stellar acuracy, however, usind 5.56 in a .223 chamber WILL lead to premature wear out of the chamber and parts.
The 5.56x45 cartridge is dimensionally similar to a .223 Remington. However, the two are not the same. A 5.56 chamber can safely fire .223 rounds, but a dedicated .223 chamber can't necessarily fire 5.56 cartridges safely, given the different angle of the cartridge neck, and the higher chamber pressures generated by the 5.56 cartridge over the commercial .223 round.
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.
yes, except 556 is written as 5.56 caliber (223) Actually, no, it isn't. Although the dimensions match, the military 5.56 cartridge differs from the civilian .223 in several aspects, such as the neck angle, casing thickness, and chamber pressure. A general rule of thumb is that .223 Remington can be fired in a 5.56 chamber, but 5.56 ammo should not be fired in a dedicated .223 chamber.
.223 Remington ammo can be safely cycled through a 5.56x45 chamber - 5.56x45 ammo should not be cycled through a .223 Remington chamber. Both types may be cycled through a .223 Wylde chamber, but .223 Wylde may only be cycled through a .223 Wylde chamber.
No. They're dimensionally similar, but vary in several aspects, and may not always be interchangeable. Generally speaking, most 5.56 chambers will do just fine firing .223 ammo, but it's not recommended to use 5.56 ammo in a .223 chamber. The one exception to this would be the 80 grain .223 Wylde - a round which specifically requires a .223 Wylde chamber.
Yes, you can. General rule of thumb is that .223 is perfectly suitable for a 5.56 chamber, but 5.56 ammo isn't suitable for a dedicated .223 chamber. The one exception to this rule is the .223 Wylde cartridge, which requires a specific .223 Wylde chamber.
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.
Yes, it was. Go to the Ruger website for more information. The military round is the 5.56x45 - while dimensionally similar to the .223 Remington, it is not entirely the same. The standard and Ranch models of the Mini 14 have a 5.56x45 chamber, which can accept both 5.56 and .223 Remington ammo. The Target models, however, have a dedicated .223 Remington chamber, and were not designed to use 5.56x45 military ammo.
The 5.56 cartridge has a different neck angle from the .223 Remington, generates higher chamber pressures, and has different weight projectiles available. .223 Remington can be safely cycled through a rifle with a 5.56 chamber, but it is not recommended to use 5.56 ammo in a rifle with a .223 chamber.
If it has a dedicated .223 Remington chamber, you should not run 5.56x45 through it.
