No doubt, and a RF has become something I don't want to leave home without. Very seldom need it for our woods hunting, but we usually are watching fields during the last hours. Some of which stretch to 400 plus a little. At distance, most that know what they are doing usually get a decent rest, they are shooting at stationary animals and ranging, dialing, etc are part of doing it right.
Addition: I'm no LR shooter, however watching those that are makes it obvious they make the time to get it as correct as possible. If they can't do it, they pass....
