Are you kidding me? You people have your heads buried in the sand so far you can't see? I don't keep up with a lot of current events but even I see the blatant, in your face, sanctimonious discrimination. What I like to call "ballistic intolerance".
5.56X45 HAS to mate with a 5.56x45 chamber? That is walking on the rights of 5.56s everywhere! If I want to stick my 5.56 in a .223 hole (that readily accepts me without being too tight about the situation) who is this manufacturer to tell me I can't?!? And Lord help us if I hook up with a .223 Wylde!
I have a friend whose parents labeled him a 5.56. Right on his head, mind you! He has always known he was really a .223. But today's climate prevents him from being what he truly is. So he must continue throwing himself into 5.56 chambers. I just feel for him because he is so limited about his self expression.
