I currently own a Remington 700 XCR in 270 win that shoots very nicely. It has a Bell and Carlson stock on it and the factory X Mark Pro trigger in it. I am thinking of making some changes but am torn between keeping the current rifle,changing the stock and upgrading the trigger and scope. The other plan would be to sell the 270.get a 7-08 place it in an upgraded stock,trigger and upgraded optics. I want to be able to use this rig on deer sized game out to 600 yards so accuracy is a must. If you were looking at building a rifle to fit this bill wich of the above two cartridge choices would you pick? This rifle will also be used on elk, but all of my elk have been killed withing 300 yards and most in dark timber so I dont need a long range elk rifle.
