After thinking on this some time and to try to get the thread back to the OP. I am gonna say , the Accurate Laser range finder is the biggest development in the last 50 years. Making longer shots has improved the guns, Bullets, scopes , bipods, field rests,and to a certain extent the shooters. More time is taken to practice making better shooters, who in return demand better equipment, not just what the gun writers of the day are writing about.
Think about JOC and Elmer in 1965, sitting on a hillside staring at a sheep 600 yds away. How many shots between them would it have taken to kill it....... Nowadays with the stuff available and to know the precise range and practice it is a cake shot.
