Yeah, I would think medium round(.260,7mm-08,.308). If it comes down to either a .270 or 30.30 , I doubt if the guys in the coal regions would have ever heard of the .270 with out a certain gun writer pushing it. The .270 is O.K., but it is hardly the wonder round it is supposed to be. Somebody said about not needing a 30.30 lever action for a follow up shot. There are a lot of .270 pumps out there.
