Its .007" away from a 7mm-08...
And so is the .270 and 280.I don't see the point here.
Personally I would like to see a .270-08. IMO it would make an even better whitetail cartridge than the 7mm-08.
They should've called the .270win the .277win in the first place.
It's called a .270 because that is the bore diameter of the barrels before the rifling is cut. The groove diameter (groove togroove)is .277 inches as is the bullet diameter.
Same with any 300 mag, 30-06, 280 Remington, .330 Dakotaetc... etc...
