I have an Armalite HB Match Stainless barrel in .223 & several Colt 5.56mm barrels that shoot the same match ammo -well, about the same.
That same Armalite barrel has seen quite a bit of 5.56 as well, with no issue.
For me, I'd say it's a wash -I wouldn't put more stock into a barrel with a Wylde chamber, but I wouldn't turn my nose up at it either.
