[QUOTE="Loner, post: 592795, member: 24560"] Back in the 80's we had what we called "the broken bolt club". The ar's with 223 chambers were the most common to fail. What was finally determined is the higher pressure 5.56 rounds would stretch the neck into the shorter tighter throat of the 223 chamber and pinch the bullet, upping the pressures. Winchester used to have a good article on it years ago. The Wylde chamber is the best of both worlds imho. New and trimmed cases are probably never going to cause a problem, but that's a guess.
