That isn't true.
On a First Focal Plane scope,the mil dots measurement value remains the same through out the entire magnification range.
And,you can use several different magnifications on most Second Focal Plane scopes if you are good at math,or make range cards with the particular measurement spec for the mil dots at a given magnification.
I can use 6/8/10/12/16/18/20/22 or 24 power to range with my Sightron SIII scopes,but each power uses a different measurement between the mil dots.
The main thing about choosing a mil dot style scope is you need to match the Turrets with the Reticle. You need either a Mil/Mil or MOA/MOA turret/reticle scope to really use the scope for ranging.
Most lower tier scopes don't offer a matched turret/reticle set-up,they have MOA turret marks,and use a Milliradian reticle.
That makes it harder to calculate the distance/scope adjustments for long range shots.
