RE: 270 Winchester Accuracy?
if you are talking about consistency, hitting the same spot over and over, the 270, 7mm, and 308 are going to all be effectively the same with similar rounds. If you are talking about flat bullet trajectory, the 7mm will be flattest on average (depending on the round used,), followed closely by the 270 and then the 308.One (that I know of-Hornady light mag 140 gr)270 roundis actually as flat as some same weight 7mm rounds, and about the same in energy. The 270 will also offer less recoil than the 7 or the 308, and this can definitely add to accuracy from a shooter consistency standpoint.
