Scope mounting question

I recently picked up a 10-22 and removed the scope to clean the rifle.
When I removed the scope from the rail, two shims fell out.
When I put the scope back on, I tried it without the shims and found that the rings did not fully tighten up on the rail. I am not sure if it is the rail or the rings.
I tried to find the answer myself and thought originally that it was for the hump issue, but now I believe the shims were on the side.
The scope is a Bushnell trophy xlt I believe, not sure about the rings( I can see no markings on the underside).
Hoping someone can tell me where my issue lies.
Should I try different rings?
Thanks
I've included a pic to show the rail and rings

Your rings look like Weaver Quad-Lock rings?
I've used them in the past with great results.
Are you trying to "clamp" the rings onto the upper centre section of the scope rail or the full outer edge of the rail?

Wham-o: They are fully seated in the slots on the rail and gripping the outer edge of the rail. Both of the rings don't fully lock. I put the rifle in my lap and I can put thumbs on both screws and slide it easily back and forth on the rail. Both screws are tightened as far as they will go.
Perhaps a better quality rail? I have not removed it to see if there are any manufacturer's markings on it.
 
That's an OEM Ruger 10/22 rail you have there Wired.
You don't hear of to many problems with those either???
Can you measure the FULL width of your rail and post your findings?
I will compare with some OEM rails I have to see if it's a width problem.
If not, it may be the rings?
 
I think I've seen this before. It was the case that the tip-off riser was holding the rings too far above the weaver rail below it making it impossible to mount. The solution was to replace the rail with something that's not trying to be a 2in1.
 
A few more showing how she sits.
The scope rings seem to fit fine onto the rail. It just seems as if the rail is not wide enough.
Looks like the rings were meant for that rail... Im not sure what to make of it.
I measured the thickness of the shim and it was 0.2mm

Wired....my OEM rail measured out at .830"
It looks like maybe the rings are sitting up slightly high due to the dove tail running down the center?
Do the cross bars not sit down in the slots of the rail, preventing it from sliding back and forth????
Maybe try another rail before you try some other rings.

It looks like your rings are using a "pass-through" nut... I can't figure out how it is possible to not be able to tighten down fully, since the rings are fully engaging the rail??? Weird... do the rings "ride-up" when you tighten them down??? Are you tightening the nuts with a flathead screw driver??? If so try to "carefully" torque them with a vise grip on the outside of the knob... your screwdriver may be bottomed out and not allowing the screw to fully seat in the nut... something to try anyway.
 
The bolts that run through do sit down in the channel. Sorry Wham-o I should have been more specific about the sliding back and forth. It only moves the amount of the excess space in the channel for the bolt(maybe 1mm). My point was that it moved freely.
Its movement is very minimal, but certainly enough to render a perfectly good scope completely useless mounted in such a manner.
The rings appear to engage the rail perfectly and the bolts are fixed and there is no play in them whatsoever.
hoytcanon: I am just using my hands to tighten the nuts, but I am confident that I am applying sufficient force to secure the nuts. Any more and I would cause damage. The nut and clamp bottoms out against the flat spot on the static part of the ring from where the bolt protrudes.
So...ultimately I will try a new rail..I'm guessing the weaver rail for the 10/22??

Here are a few more pics of the underside of the rings...(nut is not fully tightened in last pic)

Yep that's exactly the problem.

I said as much in my post before all these pictures. Trust me, it's the problem. The rings would engage properly if they could go low enough. The rings and rail are not compatible.

Get a proper rail/bases or rings with higher clearance.

You've had the answer since this morning.
 
Alberta Boy: I was no dismissing what you said. I just wanted to show as much detail to get all the facts so to speak. I thought everyone liked pics??

In any event, I am going to replace the rail with a proper weaver rail as suggested.

I'll will update the thread after I replace the rail...with a pic of course
 
Pics are good Wired. They speak a thousand words.
90% of the time you only get 1/2 of the information required to even start to assist someone.
.....and then the poster gets pissed because nobody wants to chime in to help them out. :rolleyes:

You did fine. Good luck with the new rail. :cheers:
