Most individuals will find that four hundred yards or slightly more will be the absolute maximum that they can maintain lethal accuracy. • After determining your maximum lethal range shoot a group at that distance - three or five shots will suffice. • Mark the center of the group with a large X using your felt marking pen. • Go back to the firing position and align your scope on the aiming point and note where the X is relative to the accuracy circles. Do not be concerned if the group is not in a particular circle. • Vary the power setting on the scope to move the closest circle to the center of the group. You might prefer to use the center, top or bottom of an accuracy circle, your choice. You now have a 100-yard zero and a maximum down-range zero.
