Scope sighting in question

[News Shooter]

I got a Gamo Whisperer to get rid of the squirrels on my deck. It's quite a gun.
I shoot from inside the living room to the deck railing which is 20 feet. I have dialed the scope down as far as it will go and it is still shooting 10 inches low.

Is there anything else I can do? Is it because 20 feet is just too close?

Thanks

Turn the scope 90 degrees in the mounts and try that. Jack.

I took a look at some pictures of the gun.

High velocity and what appears to be a high mounted scope.

Could be too much scope for such a close range.

If the scope mount is a see-thru type, you might be better served using the irons for up close and leave the scope sighted in for longer ranges.

I have the same problem, the scope is dead on at 50 feet but for close range shooting, I take it off and use the iron sights. Let me know how turning the scope works out for you. I have always thought that the iron sights would be much better than the scope because of where the barrel "breaks".

Some air rifles need adjustable scope mounts to correct for "barrel droop". Here's a good one from a reputable dealer. http://www.straightshooters.com/beeman/bm50391pieceadjustablemount.html

At that close of a target it might be more fun to take the scope off and use the open sights. Of course I'm assuming that the open sights will adjust well enough.

The open sights are deadly accurate at 20-30 feet. I just checked out in my back yard with a shoot-n-see and I hit the bull every time.

Thanks everyone..I'm going to give the suggestions a try tonight

We've had customers bring those back to The Lodge for that very reason. Generally, if they've mounted them on their own, they are not seated properly, or the rings are not turned down properly. I generally unmount everything, start from scratch, boresight for 30-yards and send them on their way. It works 99% of the time...

I just received this response from Gamo Customer Service.
I'll have to decipher this when I get home

Hello,

It does sound like you may have run out of adjustments. To
learn a
trick to reset the crosshairs internally, you must first unmount the
scope.

1) Turn the turret adjustment knob to "point 1 extreme" or until it can
not
turn any further.

2) While holding the turret in place; rotate the scope. Counting each
360
degree rotation it takes for your scope to reach "point 2 extreme" or
the
opposite point that the scope will not longer rotate.

3) Divide the number of scope rotations by 2. Then rotate the scope to
that
point. You should do this to both turrets as it will set both crosshair
axis' to point 0'0'.

4) Remount and rezero your scope. If you have any additional questions
or
are experiencing the same problem please contact our service center as
you
may need to send you scope in under warranty.

Please do not hesitate to contact us by phone 954-581-2144
or via e-mail response.


Thank you,

What they're trying to get into youis that they want you to crank your scope adjustment to it's center. Ex. if you crank it all the way 'til it stops and then count the clicks 'til it stops in the other direction, then go back 1/2 way.

It isn't gonna fix your problem, me thinks. I've heard of people trying reversing the scope mount or shimming at the rings with film negatives or small strips of aluminum(good way to bend/break the scope). You'd need to shim the rear ring to raise your POI. That's why they make the adjustable scope mount I mentioned in the earlier post above. With the adjustable mount, you can put your scope at the mechanical midpoint and adjust the mount 'til you're about dead on. Then you'd have almost all the adjustment left to play with on your scope turrets.

20'...use the open sights.
