I was shooting a 270 Winchester for deer and elk back in the '80s, but I convinced myself I "needed" a 30-06 - because with the 30-06's greater variety of bullet weights, it would be more versatile. So I traded my 270 off and got myself a 30-06. The flip side is I never used anything but 165gr bullets in my 30-06 - for everything from rock chucks to coyotes to mule deer to elk. As a matter of fact, 165gr bullets are all I use in my 308 Norma Magnum. Yep, my 30 caliber rifles are sure a lot more versatile than my old 270 was.
