Gamo Whisper 3-9X40 Scope

[RJMcElwain]

This the normal combo scope. I got mine last fall, and it was doing fine until recently. Suddenly, it would move six inches off bulls-eye. I'd adjust it back and then, after a few shots, have to un-adjust it back the other direction. Then it would settle down for awhile. Has anyone else run into this? And should I chalk it up as a cheap lesson and buy a good scope?

The scope that comes with the Whisper plain sucks.  After only about 100 shots (a few days with the rifle), my original scope wouldn't go past 4x.  Looking through the scope, it appeared that something had been jarred loose inside.  Gamo sent me a replacement without any trouble, and so far it has worked OK, though it has only been a few months and about 800 shots, so we'll see how long it lasts.

I plan to eventually get a Leapers or CenterPoint.  You might want to consider the same.

Most of the "Package deals" come with a cheap scope and maybe even a cheap mount.  So don't worry.....they can fail in a few shots or up to 1000s of shots.  All my "package" scopes have lasted past 1500 shots....some are still going strong.  If it's still under warranty....send the scope back and hope to get a better one....
The cheapy scope that came with my Crosman Sierra Pro died after 1000+ shots.....and it had the same problem as you described.....shots would randomly move....a few good groups here and than the POI would change.....a dozen excellent shots and then the POI would change again.  Pain in the you know what.....

The cheapy mounts have been solid for me so far......knock on wood.

Co Airgunner,

It sounds like you dealt directly with Gamo? I think I need to try that. This is actually my second Whisper. With the first one, the scope died within a few hundred shots and Cabela's replaced the whole thing. However, since I've put several hundred pellets through this one, I'd prefer to replace just the scope if I can. I think I'll try calling Gamo.

And it sounds like everyone has had the same problem. If Gamo can't help, I guess I can call it a cheap lesson and buy a better scope.

Robert what you've described is the exact same thing that happened to mine. In my case it wasn't the scope at all, but I'm not going to rule that out because they don't put the best scopes on them. What ended up being wrong was the pin in the bottom of the 1 piece scope mount was digging into the scope mounting rail due to the recoil. I didn't think to check the screws but things were moving.
I searched everywhere for a tougher mounting rail but the only thing I came up with was the stock replacement directly from Gamo.
I would check to confirm that nothing is moving, if not then you know that it's your scope. Replacing the scope is not a bad idea anyway, I went with a Leapers and a new 1 piece Accushot mount. It seems to be working well so far. Good luck.

Echoing the crowd, here.  My Hunter Elite has new glass and a new mount, both from Hawke Optics.  Everything is solid, as it should be.  The Gamo setup has been relegated to intermittent duty on my (much) lower powered springer for plinking.

On mine (bought in Febuary), the pin in the scope mount rail  didn't leave so much as a burr on the edge of the hole. I had made sure the mount and spacer rail  screws were very tight and lock-tite-ed when I got it.

The problem is that it's such a cheap scope that comes with the gun. I'm not fond of 'package guns' because a cheap scope is usually all that's used, but I couldn't get the gun without the scope. I'd just as soon they didn't bother including a scope. I'd rather put whatever Gamo spends on that scope toward a good one.

Even if I could be sure a replacement scope would hold up, since the plasic lenses are so distorted, I'm not sure it's worth the trouble of getting another from Gamo.  I don't like scopes that make it look like there's 'heat mirage' outdoors when it's only 30 degrees.

To get the scope closer to bore center line, and also have one less thing to worry about, I took that silly spacer rail off.  

Since the one-piece scope mount  is made rather well, I used that  when I put the old Tasco on. I don't know about earlier ones, but this  one-piece scope mount also has a pin that fit  into a hole in the spacer rail. Turned end-for-end and with the pin threaded up into the mount a bit more so it wouldn't catch on the piston, it lined up with the hole in the gun right where I needed it to. Since that worked out so well, I can't understand why Gamo would use that spacer ?

Anyway, it works great now !!!

The trashy 3x9x40 scope on the Gamo is only exceeded in "junk factor" by their absolutely worthless trigger.  Do yourself a favor and get rid of the Gamo scope before you find yourself going insane.  While you're at it, save your pennies and when you can spare 32 bucks, get a GRT-III trigger.

Dan, what is your opinion of the Hawke scope.  I just used my last Centerpoint and only have one Leapers left.  I wanted to pick up a couple of more scopes and have read some good things about Hawke.  Just wondering what your take on them is....

[RJMcElwain]

Thanks a lot for all the great information and confirmation of my suspicions. I'm pretty certain the mount hasn't moved because I snugged it down pretty tight and used Lock-tite on all the screws. And, the way it goes off zero just doesn't match with what I'd expect from scope creep. I think I'll call Gamo and see what they have to say. It that doesn't satisfy, I'll be getting a new scope with a different brand.

OTOH, when the scope was on target it was a great tree rat getter and tack driver.

Hi Robert,
                 Bearing in mind that I have only had the scope on the Gamo for a few weeks, I am very happy with it.  I did use it on a much milder springer that I own for a few months without any trouble.  The spring slam from my Hunter Elite is viscious, so I can't say how well the scope will hold up in the long term, but so far, all is roses.  FYI, I have the HD version in 3-9X40 and the 1-piece medium mount.
Hope this is useful.

[RJMcElwain]

FYI All,

I just talked to Gamo (I think I was talking to someone in India)  and all they will do is replace what I've got with another one just like it. Since I've  got a couple of gift certificates from Cabela's, it looks like I'll be making a trip to their store shortly.

Thanks RJ,
That's what I figured Gamo would say. Probaly cost me more to ship it back than the scope is worth.

Oh well, at least now, with a better scope and one of Charle's triggers in it, I can see what to hit, and it hits what I see.

Paul.

These gamo scopes are, without a doubt, the biggest peices of trash made.  I wouldnt mount a gamo scope to a blow gun.

Wasted many a pellet trying to sight one of these paper weights in.

Save your frustration and get a nice center point or leapers.
