You can' t go wrong with either one. I think the 7mm has a little more flat shooting but the ' 06 has more bullet choices and a higher sec. density usually. If you never plan to shoot past 200 yards ( that is a long shot no matter what anyone says or writes in a magazine) the 30-06 might be better. However, out West, where I hunt and live, there is a lot of open sage-brush country with Elk (like where I shot
mine last fall) and the 7mm would be better for longer ranges.
I would shop on finding a gun you like first then see if they have it in both calibers and go from there. BTW, I use a 7mm and have never felt using a 30-06 would have been any better on any of the game I' ve shot.
