is there a difference between 223 and 5.56 dies

Not on the outside. The inside is a different size. Your dies are fine.

And I think 5.56 has a longer throat.

There are 7 or 8 different drawings for 223-556.

95% chance your gun has a 223 Wilde chamber if it's a modern AR your speaking for

Yup. 223 Wylde chamber

The 223 can be fired in both the 5.56 and the 223 chamber. So, 223 dies would be the safe way to go--if it really would matter. Just use 223 data from your load book.

There have been a number of articles written regarding the differences, but the bottom line is: 223 is safe in a 5.56, and 5.56 may not be safe in a .223--unless the 223 has a chamber, such as the Rock River Arms' Wylde chamber or the Ruger Mini14, which are designed to handle both.
