I have an older version of this scope and actually like it a lot. I use it on a 25-06.
Trick is not to get caught up in how many MOA the lines are, because they are not calibrated like that. They are calibrated to reflect the basic ballistic profile of a magnum type rifle with a mid weight bullet. The whole reason for the reticle is TO NOT need to reference MOA tables or ballistic apps! Just use the numbers aside the reticle hash marks and use the mark that references the distance.
Now, you can also use the zoom of the scope to calibrate the reticle to the ballistic profile of your particular load. There used to be a Zeiss app for this and may still be. But you can also visit their website for a ballistic program that will allow you to do this.
When you actually shoot the solution though, don't be surprised if it doesn't exactly line up.
You can refine the zoom that fits the bullets ballistic profile by shooting at 300 yards with the solution of the program. Then, if the bullet hits low, turn the zoom down 1/8 turn until the bullet is on target. If the bullet is hitting high, turn the zoom up until the bullet is on target. I have shot with mine out to 600 yards with good accuracy once I tuned the zoom to my load.
