Re: Ian... is an author...for Nikon???
Welcome back. You picked a fine scope, am confident that it will give you good service. The prototype tactical scope parallax turret had yardage numbers on it but in reality they are not that accuate, they are just estimations. I suggested they switch to the dots with increasing size, to indicate close and farther out, because that is all we need to know to focus the scope. We have to use a laser, simple as that for distance determination. If the batteries in the laser go dead, then we can use the mildots IF we know how to make them work.
Have looked at parallax knobs of many current brands of scopes, simple fact is that the the numbers are not close enough for shooting use. Have had best focus at 100 yds when the numbers read 200 for instance. Might as well just use increasing size dots.
