The FFP I have (Monstrum Tactical) tracks quite well between magnification settings. I have checked it using chairgun and both give the same aimpoints. Using chairgun, I select the 10x mildot reticle, which is what my FFP is calibrated to.Since the mil dots change with magnification, I only have to make one range card using the 10x setting on chairgun.
I think there's some mix up here...with FFP your holdovers will be the same at ANY magnification. If there's a 5-20x magnification scope say at 75 yds you have a 3 mil dot holdover on 5x you bump up the magnification to 20x and it's still a 3 mil dot holdover. On SFP this is not true and your holdovers will change with changing the magnification. For FFP scopes all you do is pick whatever magnification you want to set up on Chairgun and once that's setup that reticle will work at any power.

My next scope is going to be ffp because of the ease of aim points and range cards no matter of the magnification.

With an ffp scope, if you aren't on a specific setting then your holdover points aren't gonig to work. I get that they will work well for range estimation, because reticle & target remain the same size throughout the zoom spectrum, & that at lower magnifications the reticles look very fine. But other than those points, is there really any other advantage of FFP over SFP?
