I'm hoping this hasn't been asked to death. I'm going to be buying my first long range rifle shortly and I want to get a Remington 700. I just don't know what I want it in. I talked to my father and was thinking about .308 or 30-06 and he said not to bother with them and that I wanted a flatter shooting round like the 7mm. However, the 7mm is twice the price and lacks the reloading options of the other two. Is there any truth to what he said?
