I had heard that some of the big bore calibers used the same bolt but came up short in my searchAre there others? I'm not aware of any. A lot of other calibers use the same carrier but require a bolt swap.

I think the case head diameter would need to be the same, which doesn't seem like it would be for large bore.I had heard that some of the big bore calibers used the same bolt but came up short in my search
6 mm ARC, 224 Valkyrie
Can't speak to 224V but 6mmARC has a larger boltface than 5.566 mm ARC, 224 Valkyrie

350 legend is basically a straight walled .223. AFAIK same bolt as a .223 AR. Aside from hunting, I see ZERO point in this cartridge but it does exist.
Yes this is my understanding. The 224V is a necked down 6.8 rem. 6mm arc is a necked down 6.5 grendel, which is derived from .300 russian
both require larger bolt face but the 6.8 rem / 224V dont push the limits of an AR bolt nearly as much as the 6arc or 6.5 grendel. the latter cartridges leave very little steel for bolt lug support. They all seem like interesting ideas until I compare them to a 69 or 77 gr 223 rem and the juice isn’t worth the squeeze (speaking just for my purposes).
