150gr bullets in both yeah maybe close to the same. But I totally disagree if you drop a 130 in a 270 then a 150 in a 30-06 then you have a whole different class of tragectory. One is built for speed the other built for variety. It all depends on what kind of shooter you are and what kind of shots you will take. Long range I'd opt for the 270win, wanting to shoot a variety of bullets and maybe load heavy bullets I'd opt for the 30-06.
