Bet it's been covered already. But here I go.

Looking at the list of bolt head sizes via a link here, I see that the .308 bolt head is listed a .001" larger than a 22/250 bolt head. Will a .308 bolt head work with a 22/250 case should I decide to go for such a barrel swap.
Just removed my first barrel so I can send it to SSS for a time and true. I am thinking get a new barrel in the meantime and need advise.

Thanks
