RE: Gettin my first deer rifle.
You can' t go wrong with either the 7mm-08 or the 270. I' d pick either of these two over the 243 simply because they give you some more options down the road. I don' t think you' ll notice much of a performance difference in either at your ranges as well. I like the 7mm-08 simply because it is a short action, but that is simply personal preferance. You won' t be sorry with either. In fact, all from the 6mms to the 8mms will not be all that different on deer within 200 yards. Find something you can shoot & they' ll all kill deer effectively.
