Thread: My Dumb Q - Making a drop chart

Hi all
My dumb question for the week:-
I am planning to go to the Auckland gong shoot but need to set up a drop chart and figure out how to then dial up the needed height on the scope for the longer shots.
I have used the JBM online site, confirmed the sighted in distance is 245yds and the drops after that. BUT to use an example, how do I convert the drop of 61.9" or 10.9MOA at 540yds into an amount to dial into the scope. Surely it can't be 10.9MOA. Would I use 2.7MOA ie 1/4 of the drop as you would use when working out a mid height rise when shooting?

Thanks
Stu
