Benefit of a wilde vs the others? A 5.56 will take both 5.56 and .223, right? How does a wilde improve on that?
I'm not trying to be dumb, just want to know answers.

I read this on the RRA website: "The .223 Wylde chamber was designed as a match chambering for semi-automatic rifles. It will accomodate both .223 Rem and 5.56mm NATO ammunition. It is relieved in the case body to aid in extraction and features a shorter throat for improved accuracy."

So, can I assume that it is mainly supposed to be more accurate because of these features than simply a 5.56, since the 5.56 can shoot both chambers, anyway.
AND, if the wylde is better, why not make EVERY ar15 that way?
