.223/5.56 difference ?

[bashmaster]

This just might be a stupid question but,

What is the real difference between the .223 and 5.56 at this point it is my understanding that the only difference is that the 5.56 is loaded to a higher pressure.

Help for the rookie?
thanks in advance

Basically this (AFAIK):
5.56 more pressure
5.56 can't fit in .223 chamber, but .223 cartridge can fit in 5.56 chamber (or maybe they fit, but the 5.56 in a .223 chamber is dangerous)
the neck on the 5.56 is angled differently giving slightly different size, hence the chamber differences.

And Leon, yes, anybody with a pulse and at least 1 month's experience on the interweb's many forums knows you must use the SEARCH button. While I didn't harsh the new guy's gig, I do wish he'd have searched and spent a day or two first before starting a thread...as many prudent newcomers should on any new board they come across.

He had more, a thread we had where it had 20000+ posts on it, got deleted

We have a life thank you, so do some other members with even higher post counts, like some of the mods and some members currently deployed to Iraq...

I have fired some 5.56 in a .223 rem T/C contender but I think I may not do this again. I wonder if I can fire steel cased ammo in that gun?
