Q:

Somethings out of whack..lol..

I changed scopes again..this one had the mil dots which are very useful now on my extra close shots,but.. I zeroed my gun at 20 yards..dead on..
I then shot it at 30 yards, it was 1 inch high and 1 inch to the right..?? 😕
the 1 inch high I can under stand, but the 1 inch to the right..?? so I then shot it at 10 yards..even more puzzling..1 inch low..which is ok..that equals 3 dots down..but this time it was 1 inch to the left.. 😕 why dead on @ 20… shoots to the right @ 30,and to the left @ 10?? thanks!

The solution to this problem is easy, and you don’t need to bother shimming, optically centering your scope or what not. If you have a laser mounted, all you do is focus your scope to the distance you’re shooting at, then when you find the laser’s dot is not aligned vertically all you do is click your scope’s windage knob to bring back the dot to the center of the reticle’s vertical line. Problem solved … hopefully.

That leaves him with the exact problem he has now! Of course he can click the windage but it will only be good for one range. Fine for shooting paper at that one rnage but not if your target will be at multiple ranges and not cooperative or patient enough for laser windage adjustments! The scope needs to be aligned with the barrel.

How can it be a problem when all he has to do is click the windage to align the laser’s dot to the vertical line of the crosshair? That is what the laser is for – it is a reference. It gives him an idea as to the direction his barrel is pointing at at the distance he is shooting. All he has to do is turn the laser on at the distance he is shooting at then if he finds that the laser is not centered while looking through his scope, all he does is click the windage to get it back centered.

he wants it so all he has to do is use his mil dots not having to adjust scope every shot say crow at 15 yards hits it the other flys and lands at 80 first at 80 he wont see laser anyway an wont have tim e to adjust id prefer a strait scope for this just use a mildot for elevaton not worrying about side to side scope adjustments

I think we should invent a tork screw driver and allen wrench set.

Done! 😆

A long scope is very easy to get shifted during instalation, I don’t know how many times I reinstalled one scope to get it right, I think we should invent a tork screw driver and allen wrench set.

Agreed, so would a yawing pellet not be an inaccurate pellet? Don’t use ’em! 😆

Yes adjustable mounts would be required for the optical centering to make a difference. Like you said there would be no point in optical centering a scope if adjustable mounts are not used after centering because after re-zeroing the scope will not be centered anymore.

Ok, now you’re contradicting what you said earlier… one of us is going crazy.

I experienced the same problem before. It’s easy to resolve and even discover the problem with a laser (I use the Air Force model) mounted to the front part of the rifle’s frame – the top part of where the front barrel screw hole is ideal. Now, when you have zeroed your laser to your scope’s zero distance you will notice that if you focus your scope at a shorter distance – before your zero point – the laser’s dot will not be lined up with the reticle, say it might be low and off to the left or right of the reticle’s vertical line. Assuming the dot is on the left, when you focus your scope to a distance farther from your zero point, the dot will be high and off to the right and of the verticle line of the scope’s reticle. When you’ve discovered such a problem, it simply means that your scope is not pointing at exactly the same direction as your barrel (which hopefully, the laser is giving reference to).

Do you have your rings set up so that they tighten to the rail from the same side? If not, make it so.

Here’s an easy way to mimic why I said I think your scope is pointing left of center: Hold your left arm (gun barrel) out straight and point at something (your 20 yard zero) on the screen. Take your right arm and point at the same spot. Now, the extended lines from your fingertips cross at the “20 yard zero.” If you shoot an imaginary pellet from your left arm at a target closer than the screen…I mean 20 yard target, it will hit to the left of the line extending from your right arm, I mean scope! If you shot at a more distant target the pellet would hit to the right of where your right arm is pointing.

Take a look at the scope and see if you can detect it not being aligned perfectly with the barrel. This could be a really simple fix like getting rings with better bases or just adding a shim to get the scope lined up.

Yes adjustable mounts would be required for the optical centering to make a difference. Like you said there would be no point in optical centering a scope if adjustable mounts are not used after centering because after re-zeroing the scope will not be centered anymore.

Your problem is going to be due to scope cant. Level the gun, step back and take a look through the scope from directly behind it. I’ll bet you 2 pennies that it isn’t level… and you’re shooting as though it is… holding the gun crooked.

It’s not an issue with optically centering. Optically centering is used when you have adjustment in the barrel of the gun or adjustable bases/mounts, etc. It allows you to get close without using all of your scopes adjustment one direction or the other.

Yes everything you said about optical centering is correct but if you have to use the scope adjustments to align the scope with the barrel it can cause your groups to be left or right at one range and the opposite at a different range. I am not sure this is the fix to problem he is having but it couldn’t hurt optically centering anyways. I have had this problem before and optically centering fixed it.

I fail to see how this is true. If you optically center the scope without adjusting the mounts/barrel; would the adjustment not go directly back to where it was when re-zeroing? Explain please.

Some pellets will spirial in there path from left to right . I know it happens to me . On one rifle I have at 15 yards I hit 1 inch to the right at about 25 yards its dead on and at 40 its about 1 inch to the left . It ihappens with powper burners as well .Marvin

I thought this at one time also and I was shown to be wrong. My problem was scope cant.
