After initially asking questions about the MilDot system, I was introduced to the Horus system. after some reading I believe it appears to be an expansion on the MilDot system. Please correct me if I am wrong ! Three questions come to mind. Firstly, according to one Oz website, this system is restricted to military and law enforcement in Oz and New Zealand. Any ideas if this is the case? Secondly, the reticles seem very cluttered (maybe busy would be a better description). Does this make the target animal hard to distinguish ? Finally, quite a lot of scopes shift off target when zoomed despite what the manufacturer may claim. It seems the real top of the range scopes appear to hold their centres. How do the scopes manufactured with the Horus system behave ? (The ones I found were makes I did not recognise.) Cheers, Pete.
