There really isn't a nickels worth of difference in these 3 rounds (or any other 3 similar standard calibers) when you get down to it...
Lets face it, most of us don't shoot past 300 yards...and within that range there is no usable difference between them.
Even at 400 yards...the 30-06 and 270 will both be around 16" low if you're using a bullet with a decent BC...the 270 may be a couple inches flatter shooting (literally...2 inches), but its just not enough to matter...
The only "REAL" difference is RECOIL...and whether or not that matters depends on the person doing the shooting.
