My reason for wanting to be able to shoot at long distance is for those times when I can't get closer. I'm not going to deliberately shoot at long ranges just to do it if I can get closer, but I do want myself and my rifle to be capable of it if the situation calls for it. The important thing as I see it is to have an accurate view of your capabilities and stay within them. If I don't have the scope magnification necessary for a long shot then I won't take it; if my scope doesn't have the field of view for a close running shot, then I won't take that either. Find a sighting system that you are comfortable with, can use well, works for the majority, if not all, of the conditions you expect to encounter, and then stay within your capabilities.
What works for me may or may not work for you. Reading through this thread I see a lot of good discussion about the pros and cons of different systems, with lots of good information to guide the choices of those still trying to figure out what works for them.
