Sayfayı YazdırUse a virtual cross point for wind correction and bullet
drop
As an alternative, you can use a virtual cross point
formed by horizontal and vertical hash mark to holdover for
both wind correction and bullet drop.
Example
Use 3 mil to compensate a 54 inch bullet drop for a target at 500 yards,
2 mil wind correction for 15 mph wind from right to left.

Hold lead correction for a moving target
Distance to your target, moving speed of your target, bullet flying time,
wind direction are the key factors that determine how much holdover
you need to hold for a moving target. As a rule of thumb, you always
hold the lead for the net distance of your target moved ( add or substract
holdover for wind correction) during the time span your bullet travelled.
Example
2 mil lead holdover for a moving target travelling at 2 mph from left to
right at 500 yards. Bullet flight time is 1 second during which the target
travelled 2.94 feet. No wind.
