MOUNTING

impact of your weapon. If you are not hitting your
aiming point (the center of the target), follow the
instructions listed in Step 4 to make the windage or
elevation adjustment needed. The below table
shows the proper amount of adjustment necessary
depending upon the range at which you are
shooting.
