223 Wylde?

Theoretical Pros which will have such a minute effect on accuracy compared to the 100's of other variables I doubt any one of us would be able to tell the difference. It is supposed to have some extra relief in the case body to help with extraction. I have a 223 wylde and have never had problems from it. Works great. I've also never had problems with the 556 chamber. I would certainly be fine with either chamber. It's way down low on the list of reasons why I would or would not buy a particular barrel. Either one is GTG IMHO
