Dialing in a Leupold scope
My son-in-law was at the range last week.His buddy had a Leupold scope on his rifle.His buddy would adjust the scope and it would not stay dialed in. One of the range workers said you had to tap on the adjusting screw to keep it from moving after making an adjustment to the scope.Has anyone ever heard of this?

Yep.
Usually when someone is adjusting a Tasco or Bushnell low-end scope, someone will invariably suggest tapping, beating or knocking the scope around to make it work.
Most scopes over $100 don't take well to this sort of treatment, and may "adjust" themselves so well that you can no longer find the reticle.
Simply lock the scope/rifle combination into a semi-rigid apparatus and make sure the knobs are pointing to zero (assuming it will already hit paper). Fire a shot.
Try 14 clicks up and fire a shot.
Try 14 clicks left and fire a shot.
Go 14 clicks down and shoot.
go 14 clicks right and make another hole that should be right next to your first shot.
You should have 4 holes in a sorta square with a flyer next to the first shot.
The size of the square at 100 yds. (assuming 1/4" clicks)should be 3 1/2 inches.
If you have a ragged hole about 1" diameter; you've set your target at the 40 yd. line (or you have a bad scope).
One other thing could be the number of shots fired in between his adjustments; maybe the barrel heated?

he needs to leave it alone and shoot for groups. If the shots wander all over the paper, the scope will not maintain zero and needs to go back for repair.
Tapping on the adjustment turrets has some merit. IF a shooter takes a scope and dials it all the way up/down or left/right, sometimes the spring will compress against one side of the main tube, and not want to release as the adjustments are being dialed back the opposite way. Smacking the turret can sometimes pop the spring back to where it provides the pressure against the erector tube and the turrets will again track correctly. It is not one of the better things that a cheap scope can have done to it,....the much higher end scopes (tactical style) are made to take impacts and not lose zero,..but they are well into the $1000 and up price range.
if you find the review of the nightforce NXS scopes on snipercountry.com you will see where the author took one of these,..and actually drove a nail with it,..then re-mounted it, and it still maintianed zero. get what ya pay for.
why chase the game when the bullet can get em from here?....

check your bases and mounts. i bet they have a higher chance of being loose than the leupold being defective. you do not need to tap any leupold. if it is defective they will repair or replace regardless 0 -
I can understand tapping on the adjustment turrets with a cheaper scope, but not a Leupold. What JustC is talking about is known as backlash and it is common with cheaper scope. Leupold scopes usually dont have this problem, and I would take a clost look at the scope mounts or the bedding of the rifle. Make sure all the screws are tight and sealed with semi-permanent loctite. If that doesnt cure it, then look at the scope itself.

One should only ever have to tap on a turret on a scope which is worth the price of a dinner out. Anything in the more acceptable quality range should not need it. It is funny this topic came up,..just 2 weeks ago I was tapping on a pards Aetec because on the savage 10ml it was on, it was shooting POORLY. After a few good raps on the turrets,..voila it held a group. Luck didn't hold very long as it soon crapped out for good and is now in the proper hands to replace whatever went south.
I do not condone wacking the turret on a high end scope. If they go haywire,..simply send them back as they are now broken and need no further injury.

read your scope dials to make sure you understand how to adjust it , if its a Leupold Rifleman they are NOT click adjustments and they move your point of impact 2 " per mark at 100 yards ,,,, so a little bit goes a long ways on the target 0 -

I think I would check EVERYTHING else first. The rest, mounts, rings, breathing, trigger pull, etc.
