ya kniw theres practically no difference if you ask me, i use a .30-06 just for that little extra punch. i have a browning bar, so recoil isnt that great since its a semi auto, but once you get to the bolts, theres more kick than a .270. a .30-06 is great for everything since you can get grain weights from i think 50 up to 220, so you can take anything from coyotes to bears.
