I see no difference between the 30-06 the 308 or the 270 as far as recoil or a big difference or trajectory out to 250 yards I do know the 30-06 has the authority as far as knock down power up close over the other 2
I've owned 270's and 30-06's in identical M700's (even made the same year) and in tang safety M77's. The 06 definitely has more recoil........
