Thread: shimming scope rings confusion

I need to put shims in the rings for a tactical scope I'm fitting because I can't wind the drop any further. I'm confused! It's shooting 0.6" high of the bull's eye. Do I put a shim in the front or rear ring?

Where is your scope adjusted to, for the .6 high impact.

Is it at full up adjustment ?

Full down adjustment ?

Centred for adjustment ?

Aah full adjustment up. So Any adjustment will make it shoot higher on the target

Shim the rear

Have you tried lapping the rings ?

Theres a forum Lapping Kit somewhere ..

I Shimmed a scope ring once on advice from someone on the the forum .... I used a sliver of coke can .... worked a treat ...

Still a bit confused. Is your elevation wound fully down and you are still high or something else?

If you want to raise your point of impact shim the rear to lower shim the front

Yeah I've tried everything. Same rings work fine with a different scope. this scope is a Leupold VXII 6-18 w tactical turrets. I've even sent it to Leupold for new mildot reticle and servicing so it should all be sweet. Shimming seems the only option left and I think it should work fine.

I've cut shims from a V can and aralditing them in but thought I'd still lap.

No it must be full adjustment down. The arrows on the turret are bloody confusing. Anti-clockwise as far as it will go which has brought the poi down until it can go no further but still .6" high

Whatever you do, DON'T glue them in ... you dont need to .. they stay in just fine by themselves !!! If you glue them in you can get them out !!

Shim the front then and yes don't glue the shim in - it wont go anywhere

Tried swapping front ring to rear and rear to front? Maybe different hights.

Shldnt that be shim the back ?? If he cant "move the shot up" any more it means the horizontal reticle bar is fully down ...

That being the case, he needs to lift up the rear of the scope to alleviate the problem ...

I might be wrong , maybe I'm the one whos got it arse about ...

in any case, its now dinner time ...

Pretty sure I can't VC. I've shimmed up the front now cheers guys. I'll have sighting in on Friday hopefully. Fingers crossed.
