I'm aware that .223 Wylde is supposedly the goldilocks chambering that preserves both the accuracy of .223 and tolerates the sometimes higher pressure of 5.56 NATO. However, is this actually a noticeable difference for average shooters or only a minor improvement that only competitive shooters would bother with?

Depends on the application. .223 wylde is a great chamber BUT it's a little tighter and therefore theoretically a little less tolerant of slightly out of spec ammo than 5.56 is.

For a match rifle, .223 wylde all thr way.

For a general purpose field rifle, 5.56.

I'm building out multiple rifles right now. I have not built a .223 wylde rifle yet.

My Rainer Arms Mountain Series 5.56 18" government profile chrome lined barrel shoots about 1-1.25 MOA with 77gr Razorcore (IMI's match grade ammo product). With Federal (old lot from 2008) XM193 it shoots a bit over 2 MOA. Ammo quality is more important than chamber for most applications.

A .223 wylde chamber will gain a very small amount on the 5.56 chamber. If you're using the gun within 200 yards the difference may not be noticeable for practical purposes.

Let the task drive the gear.

Thanks, that's exactly the type of information I was looking for.
