guys.. 75 or 77 grain bullets loaded to 2.25” in factory 556 to feed in ARs ain’t going to “jam into the lands” of a 223 chamber.
That said, I did have heavier bolt lift with some 556 ammo in my tikka factory 223 barrel. Nothing big but it was there. I promise the pressures were lower than what is needed to get the velocities touted in Sherman mag cartridges though
