to the target and divide by 1,000.
This is the observer-target (OT)
factor. If the OT distance is 1,000
meters or greater, the OT factor is
expressed to the nearest whole number.
If the OT distance is less than 1,000
meters, the OT factor is expressed to
the nearest 1/10th. For example, 800 =
0.8. Multiplying the OT factor by the
deviation measured in mils produces
deviation corrections in meters.
When the first range
spotting is observed, make a range
correction that would result in a
range spotting in the opposite
direction. For example, if the first
round is short, add enough to get an
over on the next round. This is
called successive bracketing (figure

the impact of the initial round. The
target is 2100 meters away. Since
the round is beyond the target, you
must drop. You estimate that the

meters to start successive
bracketing procedures. The round
