The 30-06 is a Remington Pump which I prefer over all other actions. I have hunted elk with the 260 and 6.5x55 as well as the 270 and several other rifles including the 280 which is sort of my current favorite. I have hunted with all the Magnums from 264 to 338 as well. I also had a 416 Rem mag for about five years or so. HOWEVER, I can see no real difference in elk hit with the 270 or the 300 Weatherby or any of the rifles I have used for elk that fall in between. The 270 has shown me plenty of power to take elk cleanly and put them down fast. I change rifles like many people change socks. I am a GUN NUT. Therefore I have tried a big share of them and realize that Elk just like deer or bear go down pretty quick when hit right and only when hit right.
