    I get confused with point of aim and point of impact.

    If my rifle's point of impact is shooting to the right of point of aim, I crank my windage to the left, to move my point of aim onto point of impact.
    The opposite applies if I adjust by using the front sight.

    In a similar way, if my point of impact is below the point of aim, I crank my elevation up.

    Or am I backwards?

    If the carbine shoots 6 inches to the left at 50 yards, the front sight needs to move to the left a touch, OR the rear sight moves a touch to the right?

    I'm confuzed and appologise for offering backasswards info, help me out here!

    I used to be very keen with this stuff, but exclusive use of optical sights in the military has made me rusty, at the range you will often see me drawing a quick sketch on a target or pantomiming a notch and post with my fingers and observing practice adjustments before applying adjustment to the rifle.

    Some definitions quickly.

    Point of aim - The place on the target where the sights have been aligned by the shooter.

    Point of impact - The place where the bullet strikes, which we want to be in the same place as the Point of aim.

    Speaking strictly to windage:

    In this exercise we are always attempting to regulate the sights to the bore, treat the bore as the fixed part of this process. If the bore were used as a sighting tube, and perfectly sighted on the bulls eye, the sights above should too be sighted on the bulls eye.

    If the sight windage is off, the bullet strikes off the target we will say the to the right of the point of aim.

    We have two options to make a correction in a perfect world, move the front sight, or move the rear sight.

    If we move the front sight, it should move to the direction of the impact, in this case we should shift it to the right until the bullet hole and the sights align. This is also correct for optical sights.

    If we move the rear sight, it should move away the direction of impact, in this case the rear sight should be shifted left until the bullet hole and the sights align.

    Does that help? been awhile since I did my Weapons Coaching courses so I may not have explained it as clearly as I had hoped.
