It is good that Arken post the product manual on FB, which I really appreciuated. TwoYoutuber start posting their EP8, but none really talk about details of the scope and more like advertising... Dear Arken, I know your KL Box might be design by "expert" but does the proportion of dots make sense for you at all? I understand the center is 50/200 zero. your fisrt dot is 400 and 2nd dot is 500....etc. The bullet drop height cannot line up between 200 to 400. Supportly somewhere in the "middle" is your 300 yard. BUT, the bullet drop between 400 to 500 if you multiple by 2 still smaller than between 200 to 400 yards down. More I wait, the more I am worry about this scope to be honest.... YOUR BULLET DROPS DOTS ARE WAY OFF. IT IS A SIMPLE MATH!
