the .270 is a very good round, it has a very flat trajectory and I know several people that hunt with it. My uncle has been hunting with that caliber longer than I can remember, prob. longer than i have been alive. Takes several deer per year with it and I know that he has taken many beyond 200 yards and even approaching 300 yards.
I am a big fan of the real flat shooting rounds. and not to change the subject but I think for myself I have decided on the .300 win mag., real flat shot with great punching power, gotta be willing to take the extra kick though.
