The 5.56 NATO chamber isn't the most accurate while the Wylde chamber is but takes the pressure levels of the 5.56. Typically, a good Wylde chambered 1:8 barrel will produce 0.5MOA groups with match ammo while a good NATO chambered barrel 1:8 or 1:7 barrel will produce 1.0 - 1.5MOA groups with match ammo.
There are some potentially tangible benefts to a Wylde chamber over a .223 & 5.56 chamber, but from my reading, it's mostly when shooting .223 Match ammo in the Wylde vs a 5.56 chamber. Since almost all my ammo will be either plinking with 5.56 milsurp and using that brass to handload ammo both for 3-Gun practice or hunting applications, I can tailor my handloads to this rifle, regardless of its chamber. So many choices:
If, I were interested in NRA Hi-Power, yes, the Wylde chamber would be prime interest, but i would've had a indeterminate wait for my upper, plus would have spent ½ again as I did on the upper. As it sits, I'm under $1700 for the whole rifle, including a match grade trigger, making slightly more'n half of which is in my scope & mount...
Other'n just five rounds of handloaded ammo the other 9 rounds were M193 milsurp. And they're what produced the .356" 3-shot group. Yet, I'm still only optimistic for the rifle's full potential. Yesterday's shoooting was off my Windham Weaponry lower, with its less than solid collapsible buttstock. I'm for for thhe Pacific Northwer and then back to TX by the end of next week. The supplier has shipped my fixed buffer tube, (somehow omitted from the package), so I can actually finish assembly of how I envision its final form.
If it has any issues with accuracy, I'm sure they're more "me" than the rifle! I guess what I'm saying is that I went with price and availability, and will have to live with the consequences!

MrMurphy,
Yes, it's
weighty alright! But out of the same can of Federal M193 ammo, my 16" Windham Weaponry SRC produced 2953fps over 5 shots; my son's Colt Commpetition 20" averaged 3053fps; and this 24" got 3163fps. All shots with the chronograph set about 10' from the muzzle.
