I noticed on proof’s website that they changed all 223 Wydle barrels to 5/8x24 muzzle thread. I have several of their barrels with 1/2x28 threads and while I understand the extra meat can be a benefit…is this change really necessary? All my barrels with 1/2x28 shoot really well. Did they announce this or just roll it out?

SOLGW is doing the same. This is the reason they list..."By incorporating more material surrounding the bore, the design minimizes constriction at the crown, improving accuracy"
Button rifled barrels open up with a 1/2x28 muzzle. Hammer forged barrels sometimes get tighter.
5/8x24 should have been the standard long ago.

Someone once shared this. I found it fascinating.
I think the one downside to this is that some suppressor companies like Surefire, make 1/2-28 muzzle devices that only work with 556 cans. With their system, a 556 suppressor physically will not mount to a 5/8-24 muzzle device.
I saw that video as well. I remember running across a torque spec, some time ago, for muzzle devices. I suppose that most use crush washers for muzzle devices, so it wasn't a common question or a big issue. Since silencers have become so much more common, I'm starting to see the question of muzzle device torque pop up more often. If I recall, the spec calls for 20-30 ft-lbs regardless of thread size, which I found odd. You would think that the larger thread would take more torque.
Anyway, surefire needs to get with the times and get into some HUB compatibility.
