This long range stuff has been going on for far more than 50 years.. I doubt it goes away, with improvements in scopes, range finders, etc... I would guess it will only continue to grow..
Long range 10 years ago was 4-500 yards with a hunting rifle. Not 800 with a 10+ lb sniper wanna be rig. It's about as ridiculous as the tactic oil guys that show up to the range looking like delta force albeit 8lbs too heavy.
