so if one were to swap barrels from same make and model from 22-250 to 308 you would be good to go?
As others have said, it's not exactly based on the 308, however, they do both share the important dimensions concerned with a swap, the bolt face and same general length (short action).
So a swap from 308 to 22-250 (or vice versa) is a very straightforward job. The only issue in "swapping" another barrel on to your action is to check headspace. Otherwise, it's pretty much a plug and play operation.
