About half of the streets in downtown Atlanta will give you well over 500 yards.Unfortunately a lot of us live in urban environments, so yes, concealment will be of great advantage to many. Show me consistent 3-500 yard unobstructed urban areas of potential conflict, and I'd gladly choose a rifle instead.
When you're shopping for the rifle keep in mind that the little extra weight of an HBAR increases accuracy dramatically and is well worth it.
