Use 

a virtual 

cross point 

for wind correction 

and bullet 

drop

 

As an alternative, you can use a v

irtual

 cross point 

formed by horizontal and vertical hash mark to holdover for 

both wind correction and bullet drop.

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. 

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. 

Example

Use 3 mil 

to compensate a 5

4 inch bullet drop for 

target at 500 yards, 

2 mil wind correction for 15 mph wind

 from right to left.
