As much as I love my 280 I can't honestly say that there is enough difference between it and a 270 that anyone would ever notice.

If you want more energy at longer ranges with similar recoil , you need to increase the caliber and weight of the bullet. For instance, a 338-06 shoots a 200gr bullet at similar velocity and tragectory as a 30-06 shoots a 180gr bullet and with simliar recoil but the 338 bullet will hit harder when it gets there.
