I'd def use a 5.56 chamber instead of a Wylde.
Noted, but why?
It's a looser chamber with a sharper rifling lead. Looser chambers are more reliable with a variety of ammo in a variety of conditions. I don't think you'll ever shoot single load bullets in it (80SRA, etc) and I believe the sharper angle leads are a tiny bit more wear resistant.
A neighborhood manufacturer swears there's not enough difference in accuracy between a Wylde and a 5.56 to comment about when using mag length ammo with jump-tolerant bullets. All the reports I've seen on their barrels (Wilson kinda barrels chambered by them) indicate they shoot very well, right around MOA and possibly less, if you can believe anyone on the web.
