The 7mm has an advantage over 30 cal, comparable BC's with lighter bullets. Both the 280 Rem and the 30-06 will work well on elk. just use a good bullet and put it where it needs to go.
Since you are reloading, consider the 280 AI. Great cartridge that steps on the heels of the 7mm Rem Mag with less powder burned. I get 3000 fps with a 160 gr AB out of a 24" barrel 280 AI and it is more than enough to cleanly take elk at 600 yds. You can also shoot factory 280 Rem in the 280 AI.
