I have only SFP scopes but that is false. maybe they are talking about things like the B&C reticle from Leupold and the Rapid Z reticles from Zeiss because those can be calibrated with magnification settings, but more accurate at long range it is not.
I have a 4.5-14x40mm LR Leupold on my 7mm, its a great scope for it. Has the Boone and Crockett Reticle so I can use that out to 550 yards or I can dial.
