So I'm looking at the Zeiss 4-14 with the Rapid-Z800 and trying to figure out how closely it will line up, so I went on to the Zeiss website and used their calculator for a few approximations of my loads, and things didn't seem to link up well.

Heres and example of one

Ok so thats at max power of 14x and as you can see the 300yard bar is a little short, the 400 a bit shorter, and so on and so on. So I was wondering how far off impact would be if say I was taking a shot at a target known to be at 400 or 500 yards assuming that I do my part and the wind is calm.

So I opened up a ballistics calculator and put in the same values, and got this

Now I'm not sure that I fully understand all of this but It would appear that if I take that shoot at 400 yard target on the 400 yard mark that it will hit zero at 372yard and then drop another 6 or so inches, so if I was on center of a 4" dot at 400 that the impact will be 4" outside of the bottom of the dot?

Likewise a 500 yard shot zeroing at 460 yards and then dropping 10.5 inches or likely completely off the target?

Am I looking at this correctly?

Note I know it will recalculate a better magnification, in this case its 10-11x I'm just wondering if I am actually understanding what I'm looking at, and how far off it will be at maximum power.

Thanks
