Ordering a .223 barrel soon for a build to launch some heavy 22 bullets. Is there any benefit to having a wylde chamber rather than a standard 223 on a bolt gun?
Any real benefit for a wylde chamber?

Wylde for heavier (75+ grains) bullets loaded long - and 1:7 - 1:7.5 twist.
My most recent build is chambered for 5.56 NATO. I'm still tinkering with load development, but so far the longer throat is providing better velocities at lower pressure (as indicated by primer flattening and ejector marks) with 77gr SMKs and 75gr ELD-Ms than my now-sold Tikka T3X Varmint .223. 80gr SMKs up next just because I have a few to try.
I have a 1:8 Bartlein barrel on this one because Bugholes had the length and contour I wanted in stock. I would have preferred a bit faster twist, but so far the 1:8 has done just fine. It won't stabilize the really long, really heavy for caliber bullets (like Berger 90s), but the 75gr ELD-M will get me to 1000 still comfortably supersonic without crazy-hot loading, so I'm good.

How heavy are you going for? I have a Criterion 223 match, it has a .09x throat. It work well with 80s.
Incorrect. I, and several other knowledgeable riflemen I know, shot factory 5.56x45 mk262 77s out of our long-throated (for a standard .223 chamber) rifles for years - understanding the caveat that a standard .223 chamber would cause dangerous pressure spikes.
But there is absolutely no problem shooting .223 Rem in a 5.56mm NATO rifle. Here's the SAAMI FAQ on it.
Well... my .223 with a regular .223 barrel shot the same groups with the same ammo as my friends snaz-nuts .223 Wylde barreled rifle.
That is until I put anything more than 70 gr. through it. But that's more of twist rate kabob than anything.
What's the root of the question here? Is the Wylde barrel more expensive? The Wylde chambering is effectively the best of the 5.56 and 223 smooshed together into a wonderous mix of potential. So... just get it and move on with life. Ideally in stainless, because that's cool.

You are absolutely correct. You can shoot a .223 out of a rifle chambered in 5.56. Shooting a 5.56 in a .223 chamber will create a high pressure situation. Do I understand correctly?
The Wylde or longer. If you google search there have been some pretty good discussions here on 223 throating for different bullets. I had a Wylde chamber cut for mine. It put the 75 a man about .02 off the lands @ 2.47 OAL. My AI 223 mags will hold 2.52 or a little more. I know some people said they liked their freebore closer to .100 for the 80g+ stuff.
