If I'm reading this right, the .22-250 bolt is compatible with the .308-based calibers?

Looks like the boltface on the .223 is a little smaller, but the only thing I need to replace to change calibers on my .22-250 is a properly headspaced barrel chambered for .243, .260, 7mm-08 or .308, since they're all on the same case. Is that correct? Is the detachable box the same too?
