the 270 still isn't the total long range answer, the berger bullets out in .277 still aren't that high a BC, berger admitted they held back a bit on the profile of the bullet. the .284 and .264 bores still have a sizeable advantage IMO for really long range I am talking beyond 500 yards. if you wanna wack something way out there try a 140 berger from a 264 win mag at 3200 fps, thatall getter done.
