Faced with the same basic decision to make, I chose the 7mm Rem Mag, because it shoots as flat as the .270 and hits as hard as the 30.06. Its recoil is comparable to the 30.06. I use 140-150 grain bullets for whitetails, and plan to use it this fall for caribou in Quebec, and then for moose in Ontario and elk out west in years to come. But that's just me, and we all know you can't have too many guns
