5.56 and .223 are both GTG correct??

Any issues with stuck cases due to it being a tighter chamber??

Thanks

As a practical matter, the chambers are the same size and only vary by a few 1/1000ths in a couple of dimensions.  The major difference is in the throat.  The answer to your question is yes.  .223 and 5.56 are gtg.

It doesn't have a tighter chamber, the throat is in between the 556 and 223 Remington. This is the best way to get top accuracy and be able to shoot the 556 or 223 Remington safetly in your rifle.

A common issue is that lots of people think the three chambers are actually different, they are not.  In fact the chambers are actually identical.  The only difference is the throat length.  The .223 Rem has a relatively short throat/free bore before the bullet contacts the lands in the barrel.  The military 5.56 NATO chamber has a very long throat to help reduce chamber pressures associated with mil spec ammo.  The Wylde chamber is a "Happy Medium" between the two extremes.
