That's really got nothing to do with the scope... rather review Horus's reticle datasheet.
The Horus H59 has a central vertical crosshair of 0.055 Mil.
At 2000yds 1 Mil is 72", which makes the reticle 3.96" wide.
At 1500yds 1 Mil is 54", which makes the reticle 2.97" wide.
... and that will be the same in any scope that contains a H59 reticle.
Would have to be a pretty skinny man sized steel target to hide behind that.
