I'm looking at your chart, if I'm reading it correctly, you have a 20yrd zero and by 75yds it's dropped over 5 inches, with the ballistic calculator I use, it only drops about 2 inchs at that distance, maybe I input the info wrong. I'm still fairly new to this, but a 5 inch rise by moving the target 25 yrd just seems excessive to me, am I wrong or is that really plausible? I'm using factory ammo hornady american white 165grn with a 16 inch barrel, not sure about the actual velocity but I'm inputting 2500fps into the calculator.
