I have been looking into get a bushnell elite tactical 10x40. The adjustment knobs are 1/10th mil. I not sure I completely understand how the whole thing works. This what I understand... Say your target is 1000 yards your bullet drop is 25.3 moa. You would divid 25.3 by 3.43 and get 7.4 mil. With the the scope on zero you would turn the knob until you are 7 then go .4 mils pass that and you should be dead on. If of corse your Zeroed right. That's how I understood it, please let me know if I'm right or wrong any help would be great. Thanks
