I have said for many years now the difference between a 223 and a 5.56 chamber is about 1000 rounds worth of throat erosion out of the 223. Tests has proved this out as well.

Seems there is NOT a pressure problem using 5.56 in a 223 chamber whatsoever. Better science than Fauci junk science. Just saying
