Don't think the extra recoil and ammo availability gives any edge to the 7mm vs. the -06. 06 ammo is relatively cheap, easy to find even in the smallest hardware store in Nowheresville, and will take any game in N. America. Ballistic charts really don't show glaring advantages of the 7mm either, but to each his own.
For that matter, the .270 will take even the largest elk. Been there, seen that.
