While I'm a 7mm Mag owner, I always recommend the .270 win. Ballistics are pretty close to that of the 7mm mag. Between a .30-06 and 7mm mag there isn't a ton of difference. 7 mag will generally be flatter but you can shoot a bigger bullet with the '06. They'll both kill anything you hit well and they kick about the same in my experience. I just ordered a VX3i 3.5-10 last night (thanks to everyone on the forum!). I don't see a big reason to have a scope that goes to 14x I've shot at 12x and it seems a bit too twitchy and the field of view is tiny. I suppose if you're shooting something past 400 yards it could be nice.
