What are the benefits of .223 Wylde vs 5.56?

[Ebola]

If 5.56 chambers and fires .223 just fine, what advantage does .223 Wylde have over 5.56 to make it a relevant chambering?

Supposedly the Wylde is more precise--5.56 main chamber married to a .223 Rem freebore, so you get the best of both worlds. At least, that's the theory...

From the Wilson Combat website:

The .223 Wylde is a hybrid .223/5.56 chamber designed by Bill Wylde to yield the accuracy advantages of the match .223 Remington commercial chambering, but without pressure or reliability failures when using high velocity 5.56 NATO spec ammunition. The .223 Wylde achieves better accuracy by having a chamber throat that is tighter than 5.56, but will still function reliably with military 5.56 ammunition because the case dimensions are the same. These facts lead to the .223 Wylde having superior target and varmint accuracy, a compatibility with all .223 and 5.56 NATO ammunitions, and being a top choice for competition shooters.

Has anyone put the accuracy claim to a definitive test?

It looks like the Wk180c is having issues with this chambering. A couple of threads on it now. Glad I held off on buying one until it is sorted out. Protruded primers, squibs, separations and fte. I don't know if this is a chambering issue specific to the 180, but I've been following its development closely with interest in the wylde design.

I doubt that has anything to do with the Wylde chamber, I've owned numerous 223's with a Wylde chamber and never had an issue. If it is the chamber it would be that it was cut incorrectly.
I haven't read any of those reports on the 180C, I'll have to look into it as I have been thinking of giving one a try due to all the happy new owners reports I've read so far.

Only way to do that would be to take two identical barrel blanks and cut the two chambers and profile them exactly the same then mount them in two identical rifles with the same optics and then run a full ammo test on them and document it all. Not exactly practical and not a fair test unless all other elements of the test rifles was identical. You can't take a factory cheapo barrel with a 223 chamber in an XCR or something similar and compare it to my McGowan barreled ACR with a Wylde chamber, apples to oranges and the test is flawed.

if you want to buy me some spare barrels I am more then willing to I chambered my AR in wylde because I wanted to sling heavier projectiles like a 5.56, but I wanted the better accuracy. I have no way to tell if my barrel would be more accurate if it was chambered in 223 rem or 5.56, but I can tell you it is sub MOA, and I can put rounds in to the head of a figure 11 target at 600 meters with little effort if the wind co-operates.
