Thread: Question on Ranger 3-9x40

I think the Ranger is a second focal plane, meaning the distance between the lines changes relative to real world measurements as you rotate the zoom ring.

Real world again, for a SFP scope the lines in the reticle are useful at one power on the zoom ring otherwise you have to do a heap of mental arithmetic to work it out and for most humans it's too hard.

If you want to work this out to something that's meaningful, mark up a piece of plywood or the like with lines at 100mm spacing so you can see them in the scope and set it up at 100m. Then you can work out exactly what distance means what in the scope at what power.

If this is useful for your rifle also depends on the caliber of the rifle and the trajectory of your load (bullet weight and ballistic coefficient with muzzle velocity) but for most calibers 1' up at 100 is still "point blank" at 200m i.e. aim with the crosshairs on what you want to hit and the bullet will be close.
