Why buy .223?

[OutRider]

...I think this is the rite forum for this...

...why would anyone buy a .223 instead of 5.56x45 chamber...???...

...does the same situation of "the same but not" exist between the.308 and the 7.62x51...???...

Maybe to match throat length to a particular bullet they desire to use?
