180 gr 270 Win??? All I can picture in my mind is a great big Carcano with that LOOOOONG bouit sticking out of it. I know it has to be seated deep to clear the lands but that is what popped into my mind. I will never forget the 1st time I saw the 6.5 Carcano round. I was maybe 15 and even then I could not see how that bullet didn't tumble once it left the barrel. Wierd round.
