The maximum COL is limited by the magazine. There may be no benifit from a Wylde chamber, unless single loading.
The original M16A1 carbine, made by Colt, has a longer chamber then AR15s , measured head to datum. The chamber specs may be different on your "test gun"
Freebore Length- The Wylde may allow more bullet jump to the rifling? Reducing pressure? It may also except longer then normal bullets, longer COL.
I would be sure to check for correct head clearance when fitting the new barrel.
Just how i see it.
Not an expert on M16s. I only checked head clearance before sell, to know it was safe.

The barrel extension & bolt automatically set head clearance (headspace). Hopefully. Best if barrel and bolt are of the same manufacture. Mismatched parts may lead to excessive head clearance or to little .

maybe likes firearms a little bit…
I imagine it’s going to resemble a 5.56 chamber in short order anyway…
Or rather the throat will. The chamber will remain the same and identical to the 5.56 already.
The longer, larger diameter throat and shallower lead into the rifling reduces pressure, that is then replaced by loading the case to “5.56 NATO”.
So, if the bulk of what one will be shooting is NATO type ammunition, I would get a 5.56 throat. A shorter steeper throat may increase pressures, in an otherwise already intense loading.
This extra pressure will cause the rifle to cycle more quickly too, perhaps causing unnecessary wear.
The Wylde chamber was to bridge from the NATO Safe 5.56 to the accurate commercial .223. Yes, no one wants an inaccurate rifle, but that’s not part of the argument with a machine gun. That also doesn’t mean there aren’t very accurate 5.56 chambered barrels.
If I was handloading to feed a hungry flame thrower as cheaply as I could. And also seeing some pretty scary bulk ammunition results that I wouldn’t want through my registered lower, I would purchase what ever chambering was available for the barrel I wanted and load for it. Knowing it will soon have a much worn throat, lead, and gas port, and still be having more fun than human being should be allowed to have!
Since I cannot afford the fun of a full auto, even with handloading, and don’t have one, and envy you greatly for it, you hardworking lucky bum, I can’t speak from true experience.
In that light, could I ask for maybe a build thread or a range report?
The closest I have is a binary AR I use with a dedicated rimfire upper. And while fun, a lot, it’s not the same. Hopefully when I retire there will still be some M-11s around for me.(Sigh.)

What are you testing for?
That would make the difference on what equipment I choose to test with.

I'm a firm believer, based on experience out to 300yds, there's nothing a Wyld chamber will do for you that a 5.56 won't.
It doesn't really matter. What feeds and works in semi auto will do so with full auto as well. You'll probably fry the barrel and chamber throat in short order if you lean into it for a while with selector set forward, but I assume you already know that and don't mind doing so.
Have fun!

Chrome bores and chambers last longer on full auto.
If you search here https://discover.dtic.mil/ the Gov has done most all the testing needed on the M16 & M4. Like this-
