Skywalker, as Koshkin mentioned, don't try to zero your scope with the boresighter; its only job is to get you on paper for final sight-in.  You cannot accurately establish how far above the point of aim you wish your sight-in to be during bore sighting, because there are too many variables affecting actual POI.

Remember, in order to move your POI on target UP, your reticle has to be moved DOWN.  If you turn the elevation knob toward the "up" direction and watch your reticle move, it is actually moving downward.  The same applies to your windage adjustment.  When you move the knob in either direction, the reticle is actually being compensated in the opposite direction than you would initially think.

We still have not got to the real problem, your turret adjustment is maxed out????
That can indicate a problem with your mounts or rifle. You should be able to get your crosshair and laser beam to the exact same point at about 25 yds with plenty of play in your turret adjustments (both up and down).
If you have been using a very short distance say 1 yds, then this may account why you are maxed out.

Ron is right.  That laser beam is coming out of the barrel in a perfectly straight line, while the bullet will fly along a curved path (due to gravity pulling the bullet down).  Hence actual bullet impact will always be lower than the laser beam.  Either way, laser bore sighter is only useful to get the initial shot on paper.  Final sighting in can only be done at the range.  Sight the scope in an inch or two below the laser beam and go shoot it.

I think I got it now.   THANKS!
 
No, you have it wrong. You need to have the crosshairs BELOW the projected laser dot if you wish the bullet to HIT above the POINT of aim (target center) when you actually go to shoot the rifle.

I see guys do this all the time- they boresight to a target or a laser beam and think that they are going to hit low when the crosshairs are below the beam, when in fact the opposite is true.
 Just double-checking...
Here it is...
At that angle I cannot tell, but is that objective lens cover touching the barrel???  Looks close...

So if I want to sight in 1" high at 100 yrds then I need the laser to be below the cross hair 1" with my laser?  Haven't used my laser bore sighter much at all, so still learning.

Skywalker, could you post a closeup pic showing your scope, mounts and receiver?  That might give us an idea of what the problem may be.

I finally got my Kahles KX 3X9X42 mounted on my TC Encore mounted with medium rings.  When I went to sight it in, I bore sighted it with a laser bore sighter and I have an issue.  I have turned the turret UP as far as it will go and it is still low.  What to do, what to do?  I have no clue.
