I have a Leupold 6.5-20x40 long range scope, I had a windage problem and sent it back to the factory for repair, the original problem was no adjustment to the right. I got it back, hung it on the gun and put a boresighter on, with the scope dialed all the way to the left it has 3-1/2 minutes of lash before it starts to move right. When its all the way right, movement is from the first click left and is constant. Should I send it back? Do you know why take-up is so far one way and solid the other way? Thanks, Ron Tilley
 
May not apply...but...

I had the same symptom with a Weaver T6 scope several years ago. When I substituted another scope and had the same problem, I decided to check further. What I discovered was that I was tightening the back scope ring to tight. I always had the habit of really boring down on those scope ring screws. When I loosened the back ring to a reasonable tension, the scope adjustments traveled throughout their full adjustments.

Just a thought,

It is also affected by the elevation adjustment if it is at one ''end'' of the adjustment.

You also have to realize this is a problem with all scopes that reply on a spring to push in one direction as you back a screw out... a lot of shooters will back the adjustment out farther than required and then tap the turret with a small wood block and then adjust the screw inwards.

There is no scope made that is perfect that I am aware of, but it is not really a problem if you understand how it works and how it may not work.
 
lash

I was taught to adjust a scope by always adjusting to click clockwise ( tighten against spring pressure to the final click position) ie.. when adjusting for elevation rotate pass your click upward and then tighten down to click position. Then bump the turret gently to set it. :D
Basically always remove the lash even in a scope.
