[?]are the Heads on a Rem 770 bolt the same for the 7mm Mag and the 300 win mag[?] I know the 30-06 bolt will fit several calibers. [:X]Thank you.

  The belted magnums should all be the same

  partsman,
  
  Standard belted magnums will be the same size, 0.532" rim plus some wiggle room.
  
  There are belted magnums like the .378 Weatherby and family which are larger in diameter, although I don't think that the M770 is available for such cartridges in the larger size.
  
  Best.
