Every circle has a 360 degrees circumference, and every degree is divided into 60 minutes
360 x 60 = 21,600 minutes in every circle. You are shooting from the center of the circle
Every projectile, small or large, slow or fast, falls to the ground equally far in equal time,

How to turn your 1/8 MOA scope into a 1/16 MOA scope: Caution, this method
also reduces the range of the scope by at least 50%. This method is especially useful for
short inside shooting ranges for raising/lowering
Rotate the scope 45 Degrees clockwise.
The Left/Right adjustment becomes left=up and right=down.
The Up/Down turret becomes Up=Right and Down=Left.

Once lateral center has been established turrets must be moved equally to raise/lower on
the vertical axis.

The diameter of our circle is 6875..477463712758 inches.
The radius, our shooting range, is 3437.738731856739 inches, muzzle to target.
Our shooting range muzzle to target is 286.4782276546982 feet .
We will determine the minute of angle adjustment left and right first.
Zero in on the center of a wide cardboard target. Mark the first shot with marker pen.
adjust all the way to left or right limit and shoot at the previously marked hole. Next,
adjust the scope to the opposite limit and shoot at the first marked hole. Measure the
distance in inches = Total M.O.A. adjustment - Lateral.
Loosen the scope in the rings and re-position the scope 90 degrees, zero in the scope,
and find the M.O.A. range of the vertical turret. Then reposition the scope.
Total minutes of angle can only  be determined by shooting laterally or by adjusting the
